does it really make that big a diffrence in speed and quarter mile times.?

going from stock 25 to 21 would that be a big difreence?

what about stock to sub zero 18s at 19 pnds?

I guess it depends alot on tire grip to?

people have ran some good times on 19s right?

 

The Imagine 18" are some 23 lbs, I would love to have 18" at 19 lbs. The lighter the better.

The best would be 17x8 235/45/17 at some 13.5 lbs like those centerlines
