Just installed them! The and fit, quality and performance is excellent!! I can't believe how well they hook and stick the rear end into ground when launching. I then installed a set of BFG drag radials and wow, the car launches and hooks excellent. The ride isnt bad at all, def firmer, I still have the back seats out from installing the upper and lower control arm reinforcements so I can't tell if they are noisy or not.
But the car feels completely different with both sets of reinforments installed and the lift bars. Feels tight. With the solid bushings in the lift bars I went with the reinforcements as well to prevent torque box damage. This complete set up is supplied by UMI Performance.
