        5 Top Rated Questions

        Can this support be used along with the MM panhard bar? and if so if there any added gain by using both?

        • These two parts occupy the same space, so you'd have to choose which would best benefit your goals.

        Would this or the Maximum Motorsports Panhard Bar for the 99-04 GT be a better purchase for a handling focused car?

        • Panhard bars are generally to help keep the rear axle aligned when lowering the vehicle. I would recommend this rear support kit.

        Helpful (1)

        Would this or the mm torque bar be better for road course work

        • The Swarr Automotive 8.8 in. Rear Support is designed to stabilize the axle tubes in relation to the differential housing. The Maximum Motorsports Torque arm will replace your upper control arms with a torque arm, and a panhard bar to help center the rear axle and combat wheel hop, axle shift, and increase traction. For Road course, the Torque arm will give much more noticeable gains.

        Will it fit on a 94-98 V6?

        • This rear support is not meant for use on a 7.5" rear so it won't fit any V6 Mustang unfortunately.

            Good product but won’t fit with maximum motor sports panhard bar. Tried to modify it but clearance issues. Pity but has to trash it. $200 wasted , my fault as I should have just returned it.

            Weird packaging but works well

            Kind of weird when I opened the box to find all the bolts, washers, and lock nuts in a zip lock bag. Plates where also wrapped in magazine pages. There was a little damage to the paint job also. I was thinking this was a return or something. Either way wanted to test it out. Easy to install, just had to move my rear brake lines over, install, then move them back. Rear end is a lot tighter, wheels hook up quick, no loud peeling out of tires, Just a smooth takeoff like my 2017 GT. Also installed the eibach rear sway bar at the same time.

            nice improvement

            Reading previous reviews, I was skeptical as to how big of a seat of your pants difference this could really make. I must admit, it's a very big improvement. I installed this with a BandM diff cover and under throttle, you really can feel how much tighter the whole rear end is. Good product!

            Good traction and rear handling enhancement

            Took few hours to installed them at home and once it's done, test drive met and exceeded my expectations. I already have eibach sway and JM lower control arm and this was the final piece to m rear traction mods. Car hooks like a tuna and it also enhances handling around turns. Very pleased customer!

            Swarr Bar satisfaction

            Material appearance and quality met expectations were met with a simple 1 hour installalation. Benefits gained are hard to determine as I installed lower and upper control arms and Swarr Bar at same time. The trio of mods has provided improved performance out of the hole as expected but feel each contributed individual or combined benefits that were greatly needed for my 96 Cobra

            Amazing Improvment

            There was a noticeable, amount of grip I gained when launching. I just lost a "street engagement" with a 650i a week before I put this on. I did a glorified burnout as he zipped away. So I actually got the Swarr Bar, hoping it would help and it did. I can still smoke my tires if I try but it is much better now. The only issue is that it doesn't fit great. It is a bit too long, the driver's side half circle clamp actually impedes into the path of spring travel on the rear driver spring. Not a huge deal as I don't think my springs will ever be fully compressed, but it makes it hard to tighten one of the bolts.

            Hook and Book

            I installed this without a lift just using floor jacks in about 30 minutes. Pretty straightforward design. If you have a 9/16 open end wrench and a 9/16 1/2" drive socket, a good cordless drill and a 25/64 drill bit you have all you need to do this yourself. I put this on my Kenne Bell 2.1 L equipped '96 Cobra which also has 3.73's and Nitto 05R's out back. I wasn't really having any issues with my car just added this for a bit of piece of mind and to strengthen the rear a bit. Its well made and looks like its gonna help, I'll find out at the track near the end of the month!

            Strengthend The Rear! Better Grip!

            The install was straightforward and easy. I did notice a faster launch and a little less spin on the first test drive! The rear end feels more solid. Also a noticeable gain in the corners as well. I was skeptical but now I'm very happy I purchased the Swarr Bar. Honestly the price is great and the gains are worth it!

            This is a good product if you're looking to stiffen up your rear end. Handling improved, but ride quality suffers a little bit. Worth the price for sure.

            Install was quick, longest part was tightening all the bolts. Launch performance is fantastic, stiffer axle and faster launching. I can still chirp my tires into 3d, not into 4th anymore with the swarr.

            Would hate to bend or spin an axle tube so I figured at this price I could not pass up this axle brace , the swarr bar was easy to install is well made and if you did not know it was an aftermarket part you would think it came from the factory this way . Thanks again American Muscle !

            Great Prduct

            I really like this product. Installation was easy, the only issue I had was when I was drilling my holes I broke two drill bits. Opererator error on that one. As soon as I installed it I took it for a test drive and I could tell a difference as soon as I stepped into it. I still let the tires loose so it didn't hook up as much as I expected but it was better then before. I recommend this product.

            The Swarr Bar is a very nice piece,with quality welds,and finsh.Very simple to install,took roughly 30 minutes or so to install.I have not yet seen if there is any benefits from it yet.Stang is parked for the winter.But from what i read,it should help out those axle tubes in the long run,and that's what i was looking for.

            Swarr Bar for 8.8in Rear

            Great product. Very high quality parts with easy installation. I welded the tubes before installing the bar for extra support. Metal on the rear axle is not hard. Drilling the holes was easier than I expected. Can't take the car out until the snow melts but you can tell it's going to make a big difference in holding things together. This is not a sway bar. Thank you American Muscle for supplying another great product.

            Swarr Bar

            If you want to put more horsepower to the ground, and make your stang benefit more from all the bolt on mods you have then you need this swarr bar, it kick ass, eliminates the flexing of the axles, and makes your car launch straight and puts alot more horsepower to the ground, huge difference. It will make your car faster, installation was very easy, took about 1 hour
