They come in 18" and 20". Will they fit on '94 STS. What about the ride quality with 18"? 20"?

Thanks.

According to the ad, they'll fit. Ride quality is going to suffer. Anytime you shorten the sidewall and increase the wheel height, you're going to have a crappier ride. In my humble opinion, if you want a sports car, buy a sports car. But if it's for the "bling" then I guess you have no choice. Right?

you are going to need to upgrade your breaks too to stop those big things if your getting the 20's
