when i had a stock 91 mr2 n/a i was able to feel the difference in changing direction(slalom) when moving from the 16lb wheels to a dish bbs 11 lb wheel.. the stock wheel was flat and had more weight on the outside slowing down directional change .. the bbs wheel had less weight and it was moved more inboard because of the dish .. thats my experience

i went from stock ap2v1's to rpf1's on the s2k and didnt feel as much of a change though the car felt slightly lighter on its feet

i agree u can feel the suspension work easier/ respond quicker with the light wheels
