I've had these arms and R-Joint axle bearings on my car for a little over a month and have street driven and raced them considerably already. The improvement in smoother articulation with zero bind is VERY noticeable.
The car now keeps the inside rear tire planted and the free on corner exit issue that has plagued this car forever is now gone.
Check out the Gs it holds in big sweepers now...
Nice product Ridetech!!!
