Yes they fit. Have seen some cars here in St. Louis with them. There is a Monte Carlo w/ 21" wheels here also and they fit perfect. It's all about the offset and the condition of your suspension. IMO if you can afford them and you find a wheel you like go for it. I would. I'm tired of seeing cars look exactly the same with the same drag stars, etc, etc. And wtf about our cars being performance cars....you cant have big rims... that doesnt make sense. Most performance cars nowadays come with big rims. the only thing you have to take into acct is the condition of the roads where you live. If there are alot of pot holes and rough roads i would stick with 18's. Dont' let all these old timers [who are set in there ways] scare you off...the key is the look of the rim. I've seen alot of ugly 20's but then again i've seen alot of ugly 15s, 16s, 17s, 18s,......... Just my .02
