Review & Installation Video

Hey, guys. Justin here. As you can see, actually working on my own car for once. It's a nice little change of pace. You guys always see me working on the project cars and the Bolt-on build-ups and all that stuff. Well, I wanted to let you in on what I'm working on with my own Mustang. I have mentioned my 1927 Ford a few times. I've been working on that at home of course, but I figured this was a great time to show you my main ride. Recently upgraded to the 2014 Mustang GT, track pack, some other little bells and whistles. Had to get the Recaro Seats, of course, which were a must. But anyway, we're doing some mods. Spring's just about here. So, it's finally time to start working on this thing. Concentrating on the suspension today, I'll show you guys a little bit more about that in a minute, but I had to get rid of that stock ride height. It was absolutely hideous. So, Ryan and I are working on that. But of course, I did take care of a few of the basic mods so far, so I got the C&L intake along with the Bama tune. C&L, just a great intake and if I can be a little cheesy here, the blue couplers do go nicely with those Boss coil covers if I may say. Also, I know it's a little silly, but had to get the hood struts in place. Just a nice mod to have especially when you're wrenching under the hood like Ryan's doing all the work right now. Just clears out a little extra space, so definitely a must have mod and then, of course, we did the exhaust. I actually am going with the quad-tip Magnaflow street series. They're already installed. I did the rear valance along with it which I had to cut the bumper up a little bit. You guys will see that of course, but I got a good game plan for this car. It's going to be a little aggressive, but I definitely want to go GT500 inspired, but I'm just going to have fun with it, see how it comes together. Now, we're actually going to concentrate again on suspension today and show you guys what we're working on. So, check it out. All right, guys. Definitely tackling some of the performance and suspension basics here today. For instance, we're installing the Koni STR.T shocks and struts along with the SR Performance lowering springs. Now, you guys hear me talk about those SR springs all the time. We use them on a lot of our project cars and I'm even trusting them on my own car because they're a great product. They give you one and a half inch drop on all four corners which I think is just right amount. It's not totally slammed, but again it takes care of some of that wheel gap and the STR.T's are great as well. The adjustables are nice, the Koni yellows, but for the basic use of just lowering the car, handling the lowering spring, giving you a little bit more of a sporty ride, the STR.T's are a way to go. The STR.T's are nice because you can use them with your factory top-hat or your strut mount and you don't have to use an 2005 to 2010 GT500 strut mount, but my case, I just really like to be able to dial in everything, so I'm going with the J&M caster camber plates up top here, which would really set off this package. All right, guys. Ryan and I just finished up the front. We've got the shocks in the rear, the springs in place. Now, we're moving onto the SR Performance Panhard Bar which we have installed already, but we're going to be making some adjustments and that's the important part with these adjustable panhard bars. SR does a great job, they offer double adjustability here because when you think about it, you lower the car with a standard length panhard bar and basically the rear axle wants to shift to the driver's side pushing the tire out further over there which is not a good thing. So, the adjustable bar gives you the ability to basically center the rear axle under the car which is huge in lowering of course, gives you the best performance and to do so you pretty much just got to rig up a crude little plumb-bob just to make your measurements. Load up the suspension. Make your measurements, make some small adjustments if you need to and then get this puppy centered underneath the car, so we're going to make our final adjustments and see how we look. All right, guys, so that's going to do it for today. Obviously we kept things pretty simple. Just took care of the caster/camber plates, spring, shocks, struts, and the panhard bar, but the car's finally looking good. Ride height wise, we got rid of that ugly factory wheel gap and I'm very happy with how the car's sitting now. I do have some wheels in mind for the car of course, but it is still a little nasty up here in the northeast. There's still a lot of salt on the road, so in the meantime I'm sticking with the Brembo wheels. Do have a little bit of appearance stuff coming up. You can kind of see where that GT500 theme's coming from and of course definitely going to dive into the engine bay and take care of some parts there. So, thanks for checking out my 2014 Mustang GT guys and stay tuned for more.

Perfect Alignment for Street or Strip. Whether you spend your time on the track or the street, you need a good alignment. The adjustability that these J&M caster camber plates offer will make lining things up easy and worry-free. These are the only plates on the market that have an offset design allowing for you to install them in the street orientation or a race orientation, allowing for the most camber adjustment available.

Ideal for Lowered Mustangs. If you have lowered your Mustang, you may not be able to get your suspension back in spec, resulting in accelerated tire wear or less-than-ideal handling. Get the adjustability you need to fix these issues with a set of J&M Caster Camber Plates.

Double Adjustable. J&M caster camber plates let you adjust camber without affecting caster. These J&M plates provide over 2.5 degrees of camber adjustment and 0.7 degrees of range of caster adjustment. That means you (or your shop) can adjust the variables that control how fast your tires wear and improve your stability while cornering.

Bolt-on Installation. J&M caster camber plates are the only kit that comes "complete and ready" to bolt-in right out of the box with no need to swap anything over from the factory mount or any extra drilling or cutting required.

Application. These J&M 4-Bolt Caster Camber Plates are specifically designed for use on 2011 to 2014 V6, GT and BOSS Mustangs, excludes Shelby GT500 models.Protected under US Patent Numbers 8,820,759 and 9,073,577.

Can these be used with camber caster bolts or do I need to remove and put open bolts back in?

    Amazingly easy to install and adjust

    Bought these plates when I was installing new shocks/ lowering springs and I'm glad I did. There SR springs said they would lower it about 1.5" and the new plates droped it another .5-.75" as well. These plates allow me to still run a factory alignment and have eliminated any excess camber. once the wheels are off the ground and the bolts are loosened its extremely easy to adjust the shocks to the appropriate setting. I wish they had notches or marks on the top though, so you could do a quick adjustment for the track without having to guess.

    My setup has these CC plates with the eibach sportline kit, (shocks struts springs front and rear sway bar) hotchkis double adjustable panhard bar, RTR sway bar links. I wasted three months battling BBK on their garbage after trying to install their CC. made noise, and was terrible to align. Also that stupid top cap made my strut tower brace bow out my hood. Saw that this kit was complete, a feature which should not be ignored, and went with them. Install was a breeze. Design and construction was spot on. Im only dropped .8 up front so I went with the race setup on these as instructed to keep factory specs. Alignment was dead on. I mean straight green Ford specs. No noise. No worries. No tire wear. Driving this thing is amazing. Finally on a rail as it should be and sitting where it should be. Dont waste your time on a piecemeal kit. Dont reuse parts. Don't overspend. Don't waste your time and money on inferior kits. Just buy these already. Its AM so you know they have your back.

    J M caster camber plates

    Install was simple but there was not enough adjustment for the camber. Alignment shop had to slot the koni struts to put the alignment back to factory settings. I have the notch in the street setting. I used the s/r lowering spring and koni shocks and struts to lower the car. The suspension works well on the track, i run on road course tracks, and daily driving was not compromised. I also had to modify my strut tower brace, no hole for the caster bolt. Drilled and slotted brace for adjustment.

    Pretty good...

    Bought these after putting lowering springs on and not being able to adjust camber enough to align the vehicle properly. Aligns just fine after installing these plates. Probably took about two hours to install both sides on my own. One of the plates had come apart in the box. I just put the bearings back in place without issue. Nothing fancy. They just do what they're supposed to do. Good product.

    Easy install and adjustability.

    Instructions provided detailed steps and install was simple. Adjustability was simple as well. It's only been a few weeks since I installed it but haven't experienced any noise. It drops the front end about 3/4" so you should keep that in mind when selecting springs and/or looking for a certain ride height. My setup consists of Koni Sports and Steeda Ultralite springs (1.25 drop) and it's perfect.

    Diving straight

    A real no brainer. I needed these to ensure that my alignment was correct so I wouldn't blow out another set of tires prematurely. I don't notice if I have better handling or not because I replaced the threadbare tires at the same time. Still a good purchase because it gives piece of mind that everything is working like it should.

    I am very pleased with the J and M Adjustable Caster Camber Plates that I installed on my 2013 GT. They are a much better choice than the camber bolts. In combination with the Koni STR.T struts, my GT handles much better and there are no tire wear issues.

    Good looking, everything you need

    I ended up getting this after already purchasing the GT 500 strut mounts and realizing that they do not work with '11 Struts. They were easy to install. They came with a couple sets of nuts for different threaded struts. I installed them with some Koni Yellows and the S&R springs. When I got the alignment done it mechanic said it was only a little out line.

    Don't mess with camber bolts!

    This is a must for any lowering to your vehicle, especially if you plan on tracking the car. It would have cost me almost nothing to have installed when my suspension was being done, and I would have saved a second alignment, so the old "save a nickel, save a dime, it will cost you a quarter every time" holds true. Between my Eibach suspension and Hotchkis subframe connectors I was actually experiencing understeer in turns. After the camber plates and a -2.25 setup, I spun the car out at my next track session. With some minor adjustments to my front sway bar and tire pressures the car is now perfectly neutral and flies around turns. BTW, -2.25 camber is the max they could achieve, despite J&M's claim of -2.5, but way better than camber bolts at only -1.6.

    Great product

    Extremely happy with these caster camber plates. Had my mechanic install them, he was pleasantly surprised with the setup and fitment. Installation was a breeze and adjusting the caster camber was quite easy. I will say that my front end did drop 3/4" after installation. It would seem that the spring mount isn't as large or thick as the factory unit? Can't say for sure but the car looks and handles great regardless. Highly recommend this product you won't be dissapointed!

    Design and concept good, quality of manufacture problematic

    The design concept behind these caster/camber plates seems sound, and I thought they'd work out well. However, two problems were immediately apparent: (1) The spherical center-bearing (where the shaft rides through) on one of the two units was not installed correctly by the manufacturer. It had to be re-pressed into framing, fit through installation, and then taken out and re-pressed in again. I'm still getting strange camber readings on the side this unit was installed on, which can be corrected only with the plate slid to the extreme outside. I may have to replace the unit with another. (2) While most of the hardware included with these units are first-rate, the eight top strut mounting and adjustment bolts are flimsy in materials composition and started to round out after three adjustments at 20 lbs. on a torque wrench. I replaced them with the flanged OEM bolts while keeping the washers that came with the c/c plates -- this combo worked well. Manufacturing defects and choices killed this for me. I don't mind the bad bolts overmuch, but issues with the spherical bearing may mean additional time and money in replacement, possibly with another product. I'd like to recommend the product, but at this point I can't.

    The best choice for a new suspension setup

    I recently installed these with Koni Sport Struts and H&R Super Sport springs and the finished setup is awesome. The body roll is eliminated and the drive is much firmer without feeling like a drag car. Like most of you out there I spent a long time trying to decide between camber bolts vs. J&M CC plates vs. MM CC plates. I quickly decided against camber bolts because of the inherent weakness of the stock strut mounts; I did not want them failing on me just to have to break down the entire front suspension to install the new ones in the future. I chose J&M over MM for three reasons: the price was about $80 cheaper, the camber adjustment on the J&M plates is larger and the J&M come with a complete setup meaning that you do not have to reuse any of your original strut mount parts. That is something that is not necessarily advertised about the MM CC plates: you still have to reuse half of the original strut mount. While I'm sure the original part will still work fine with the new plates I liked the idea of an entirely new setup better; the fact that J&M offers the entirely new setup for far cheaper than the alternative was icing on the cake. The new plates are of awesome construction and I am sure they will last for a very long time. If you are on the fence about CC plates pull the trigger on these; you will definitely not be upset.

    Cost effective and reliable way to get back into spec and offer customization.

    I didn't, and still don't, trust camber bolts for our cars; so I had in mind that CC plates was the way to go from the start. The J&M come ready to bolt-on right out of the box, with the ability to use either 05-10 or 11+ struts it made the choice easy and quick. The install was straight forward and Brian at J&M was available to answer questions and help with an issue when it arose. I would definitely consider J&M for other suspension needs just based on their customer service! The plates allowed my car to get perfectly and symmetrically back into spec when the alignment was done after dropping the car 1.75" in the front on BMR springs and the lower spring perch of the Koni Yellows (1.5" rear).

    Did the job perfectly!

    I bought this Plates because I bought some KONI yellow shocks for front and rear. "Unfortunately" I didn't bought the 2005-2009 front dampers but the 2011+ front dampers. So I could not use the GT500-Strut-Mounts and had to look after some different ones. All parts for the installation (in 2005+ and 2011+ Mustangs) are included, the installation manual is good and the product is well made. There were no problems during installation. I brought the car to a shop for measurement and adjustment after installation - what could I say? Everything perfect now! I can recommend this product!

    Nice upgrade for the price

    These are a direct replacement for the stock strut mounts, and they fit perfectly. I could tell they were well made as soon as I unpacked them. I lowered the car using Vogtland springs, about an inch and a half all the way around, and these were compatible. I'm assuming these would work with any lowering springs made for the car. The instructions were pretty straight forward. I can't hear any popping or noise. For the price I think these plates are a good bargain for people who want to lower their car without going with a full bore suspension replacement. Installation notes: 1. Pay close attention to torque specs. I was surprised how little some of the bolts needed to be torqued down. 2. I recommend using spring compressors. You can get by without them, but after doing it both ways, I can say I much prefer using the spring compressors. 3. You should already know this, but just to say it, make sure you get adjustable camber bolts, and an adjustable pan hard bar if you lower your car with springs.

      I'm glad you are happy with your new Caster Camber Plates. Just wanted to make one small clarification regarding your installation notes, number 3 specifically. You are correct in that you should be getting camber bolts or a set of caster camber plates such as these when lowering the car - but you wouldn't need both - just one or the other. Thanks for submitting your feedback on these J&M CC Plates!

    I was surprised at how easy the install was they provide great step by step directions. The only thing they left out was the torque specs of the top strut nut I found it on line though and a tip loosen that nut just a little bit before you take the whole assembly out. Other then that they fit and work great.
