I actually had the springs installed already last weekend. I got Neuspeed Sport Springs and now my car sits really really low. the front air flap is about 1 inch off the ground! I haven't put on the rims because i need to take my car into the dealer for some work and i also need to get my new set of stock tires mounted on my rears. If you're wondering why the HKS exhaust is sittin there too, i tried to install it last weekend and i broke one of the bolts the connects it to the cat. all 3 bolts came out crooked and when i tried to put them back in, i broke one of them. i need to get it rethreaded.

 

I have 18x7.5 and 18x8.5 racing hart c2's with 45mm offset for both front and back (I didn't pick offset, dealer did). I was worried about it for a while, but have not experienced any problems and haven't heard any rubbing, even under hard cornering. Check out the links shown on this post:

I ran across a couple of offset calculators on the web, one very simple, the other very comprehensive. If you enter the setup I have into these calculators, the 45mm offset looks fine.
