today I changed the wheels on my CF, i have installed for a test 17" rim and higher tire to bring it to the normal, or close to normal position, what a diferent in the ride WAW, the car rides still like a sports car, but it "shaved" off all the little unplesant harsh jump over the little bumps on the road, and it makes the car much quiter.I love it. my dentures do not fall off any more....
