Perfect For Street And Track. The Whiteline Watts Link Rear Suspension allows the axle to move up and down in a true vertical plane keeping it centered under the car, so that your roll center behaves exactly the same in a left hand turn as it does in a right hand turn. This allows for predictable and tune-able handling, perfect for street and track cars. Adjustable. Whiteline designed their Watts Link Rear Suspension Kit to be ride height adjustable so you can precisely dial in your optimum settings through the differential cover and 4130 Chromoly adjustable arms.

Synthetic Elastomer Bushing. This Whiteline Performance Watts Link Rear Suspension Kit uses Synthetic Elastomer bushings which reduce noise, vibration and rigidity to the rear end without the harshness of commonly used rubber bushings.

Bolt-on Design. Unlike other Watts Linkage kits on the market the Whiteline Performance kit is a true 100% bolt on with no welding required for installation.

Application. Designed to fit all 2005 to 2014 Mustang coupes, including the V6, GT, Bullitt and Shelby GT500 models, the Whiteline Performance Complete Watts Link Rear Suspension requires removal of the factory panhard bar and rear brace.

    Outstanding product, great ride improvement

    March 10, 2013

    First, the pros: Great looks and clean packaging under the car. Compatible with my Ford Racing sway bar. Very nice to have additional fill and drain plugs on the differential cover. The lower drain plug has a magnet as well to capture metal shards. I couldn't believe how much this helped the ride and handling. Simply driving down the highway I can feel how much more settled down the rear end of the car feels. Others have describe it as better damped, and I would agree. The rear end "wiggle" that accompanied bumps before the install is nearly completely gone. Other users aren't lying when they say it feels more like an IRS setup: bumps on one side of the car have much less effect on upsetting the car overall. After two weeks, the Whiteline bushings are living up to their hype of no NVH added. All parts of the watts link appear top notch and very solid. After two weeks of daily driving on some bad local roads and nothing appears to be in danger of coming loose. The cons: Expensive, even when you ignore that other watts link products cost more (but worth it). Adjustments are more complex than an adjustable panhard bar. The upper right control arm is difficult to reach in order to make adjustments. The car needs to be jacked up and the rear axle allowed to hang. Even then, the jam nut on the upper right control arm is hidden by the passenger side sheet metal that it attaches to (where the panhard bar brace used to attach to). Getting a wrench in there is a pain. I had some issues with incorrect torque values in the directions. Whiteline has updated their online directions and they replaced all broken hardware that resulted, but it was a major headache. I highly recommend that you reference the factory torque values for all factory bolts that you reuse. They should now match Whiteline's directions, but it'll keep you safe. Neutral issues: Only two ride height adjustments (Steeda and Fays offer a lot more). I call this a neutral issue because I don't track my car and probably will never notice the difference. My Ford Racing rear sway bar is compatible, but it does contact the watts link if I raise the vehicle and let the rear axle hang. I can either let it do this, or disconnect the sway bar. Not a deal breaker, but another added step when working on the car.

White line will be the rest of my suspension parts they seem to have it figured out. I dive my car daily an I'm always smiling in turns. Going a lot faster then posted. Thanks White line look forward to buying the rest of your parts.

    Whiteline Watts

    September 26, 2014

    I installed this Watts Link as the last handling mod. It should have been my first. Install took about 4 hours including jacking the car. No portion of the install is difficult but you will need 2 qts of rear gear oil. I recommend Royal Purple (75w-140). You can tape string and a couple of heavy washers as plumb bobs to the rear fenders after install and adjust the links until both rear wheel lips measure flush with the plumb bobs to ensure the equal adjustment of the rear wheels post install. The Watts Link cleaned up the sometimes twitchy rear end during corner exit and allowed me to use the supercharger's boost earlier on the corner exit. The rear is more stable mid corner over bumps. Unlike some handling modifications, this one is totally silent over bumps. Additionally, it allows you to run 11 and 12 inch wide wheels without concerns related to contact with the inner fender well like the panhard bar does. It was a good addition. I know it is expensive but it truly is a quality piece of art.

    Whiteline Watts link

    October 24, 2013

    The unit came well boxed and undamaged, the unit was in excellent condition. The instructions could be a bit clearer, installation was relatively straight forward as long as you have all the necessary tools, installation took me about 6 hours. The handling improvement however was huge, I love the way it handles out on curvy country roads, the axle hop is all but gone, and in its place is nothing but confidence. I highly recommend it, sure it's a bit pricey, but if you detest the mid corner jitters of the solid rear axle then this is the upgrade you need.

    Best mod I have ever made

    July 30, 2013

    My mustang has always been an odd one to my friends simply because Im so suspension crazy. This mod is by far the best thing I have ever done. Coupled with my sway bars and coilovers my mustang handles like a beast now. My suspension is not the limiting factor in my handling anymore, i actually need stickier tires to keep up with the rest. The install did take all day and I seriously mean all day. The instructions are eh and some of their torque numbers are wrong. That and they tell you to torque certain items after you have bolted other sections in and the spare tire well makes it impossible. So you have to think ahead of the instructions a bit. Otherwise the fitment was amazing. I have the eibach sway bars and ground down part of the new panhard brace that could have come into contact with my endlinks but the unit didnt, even when not under load which was awesome. TL;DR this is the best money I have ever spent on my mustang. If you like going on twisty roads and you are sick of getting lip from your import friends, get this

    It was what this car was missing!

    May 02, 2014

    This watts link was pretty straight forward to install as long as you took your time. The fit and finish are incredible and the adjustability is easy. The ride is so much more controlled now. Still waiting for the next track day thou to see how well it handles in race day conditions.
