haha DO IT, you can be the guinea pig. I'm gonna get some BFG's for my steelies and share them with the SER and civic, luckily they are both 4X100 bolt pattern.

I know when i had my 17" monsoons on there with nitrous i raced my friend's spec v and would pull him about 3. I put my steelies back on and it jumped to a consistent 6 every time. The rotational mass/weight of the 17's just kills our cars. You can get a 205 wide 15" wheel and still have the grip.
