would that mess up gas milage at all ? ya i really want to drop the car like an inch and half in the front and the same in the rear get new control arms, front and rear sway bars.. pretty get a good set up for both road racing 9 cuz its mad fun tearing up roads like spice wood springs and to be safe at the same time0 and something good for drag racing... i will prolly go with eibach sportlines ive heard some good things like that with tegs it doesnt do a extreme drop and if it turns out it does then the pro kit is more for me due to the speed bumps where i live i will get stuck on them
