Yeah, I'd have to say in my short time on this board I've learned a couple of things
A:Turbo buick owners on this board are some of the most one-sided opinionated people in the world
B:Some things you just don't talk about on this board(20" rims, blow off valves and racing your TR any other way than in a straight line for an 1/8th or 1/4 mile at a time)
Allthough, you did post this in a technical forum (not the lounge) and didn't ask for opinion just technical info.
I say do what you want and it's not like you can't go back if YOU don't like it. I have seen 20's on regals a lot and you didn't say whether or not your car is lowered or not or if thats in your future plans. You may wind up with a larger overall dia. tire and throw off your speedo, but that's all.
hope that helps,
