can i put 20" rims on my 1991 3000gt vr4?

would it clear the suspension?

20's will fit with proper tire sizing but it looks like complete ass in my opinion. 20's belong on Caddy's and Lincolns, not sports cars.

the highest i would go is 18s maybe 19s but never 20s i heard that sometimes they had problems turning.

There will be no problems turning as long you use the proper aspect ratio tire.

But again, 20's are a no no on sports cars. ;)

Please, stick to 18's or you'll end up like this guy.

^ROFL, thats freaking great...

I agree though. Yea, they'll fit, but you'll lose all ride comfort and handling, not to mention looking like that guy above. 19s is the absolute max i would ever put on these cars, 18s is the perfect size IMO.

also, you'll probably end up denting them anyways the first time you hit a bump or pothole, since you're going top need extremely low profile tires. (expensive)
