handling..... light and responsive.
grip.............. far superior
lightness......feels light steering AND IM A MANUAL RACK
it does make some noise now that ive had it on for 6 months.
car handles better with 165/r/-15 than it did with stock suspension and 205 50-16---with camber
I have an UPR K member, MM Castor Camber MM coil over with bilstein shiocks.. My car is a 2003 Mach 1. I have 275/40/17 fronts and 315/35/17 on back. Oh yeah i have power steering, but i have solid rack bushings , front sway bar and bump steer.
I have to say that my car handles very well very tight in the turns, turning radius is better, but like most say there is a little noise. My car needs an alignment still, maybe that will help the noise.
Interested in hearing about your turn out and what system did you go with.
I went with the UPR only because it was lighter than the MM. It was /is the best bang for my buck. getting to my engine from under the car is excellent, accessing my headers etc awesome !
