I've read that the PUP doesn't change shocks or springs, just drops the car 1cm. Has anyone confirmed this as fact? I ask because I drove a RWD with 18's back-to-back with an AWD with 20's and the turn in was night and day different. The 18's were a lot squisher feeling. I expected the taller profile all-seasons to make a difference, but I'm left wondering whether some of it was the suspension as well.
