Wheel Hop?

What can I buy to get rid of the very annoying wheel hop on my 2011 GT. Also does anyone know of a company that offers a black interior swap. I bought my GT with the tan interior and I would prefer the black leather.

I installed BMR upper and lower controls arms and it eliminated the wheel hop. the trade off is more interior noise due to the harder bushing, but the wheel hop is gone. As for the interior, maybe you can have it dyed.
 
Roush upper is a quiet, simple way to eliminate the WH. Axle seems connected to the throttle and getting on the gas doesn't seem like it's gonna leave the rear end on the road, American Grafitti style.
 
I will be installing a Spohn Del-sphere UCA in a few days by itself and will report back.

Axle windup (main cause of wheel hop) is controlled by the upper and lower control arms. Since there is only one UCA vs two lowers, it's reasonable to say that the upper will have a bigger effect.

Avoid the temptation to put upper or lower arms on with poly bushings on both ends. The arms need to twist as the suspension articulates. Poly bushings do not allow this and will bind.
 
Based on the fact that I driven the car for over a year sine I had them installed and nothing is binding. Or at least not that I can feel. The upper has a poly bushing on the body end and use the factory bushing in the differential end. The lowers use poly bushing at both ends.
 
Or at least not that I can feel.

That is my point. It's not a knock against you, but just because you don't feel it, doesn't mean it isn't happening.

Leaving rubber on one side of the upper arm is probably good enough to allow for it to articulate, but the lowers are causing bind. Basically, as the car's body rolls, the bind raises the wheel rate unpredictably and reduces grip. This can fatigue the chassis mounts over time too.
 
OK if you says so. I can't see not noticing something like you described. All I know is that axle hop has been completely eliminated, the cars pulls better out of the hole and the rear feels more stable , less twitchy during hard corning. The arms I bought have spherical bearings surrounded by a polyurethane bushing at the axle end so maybe that is why I feel no binding.
 
Hahaha, well yeah! :D

I was talking about having arms that use poly on both ends. Having either a spherical bearing, or similar is plenty to allow good articulation.

I just installed a Spohn adjustable poly / del-sphere panhard bar today. I'm happy to say that I haven't noticed any increase in NVH from the change.

It's also worth mentioning that when I installed it, it was set to the factory length, but I did have to clock the del-sphere joint. With the mounting bolts torqued down and the car at rode height, the del-sphere joint was near one side of its range. A quick tweak with a wrench and it was right in the middle.

I had wondered whether it was necessary to include an articulating joint in the panhard bar. But after seeing some misalignment between axle and chassis side brackets and then factoring in axle wrap, it makes a lot of sense to do so.
 
UPR upper & J&M lowers

Sweet. I just installed the UPR UCA & mount on my car this weekend. I can feel the difference!
