Dude, for $400 they should include a 3-some with 2 bi-lesbo chicks and a VIP pass to your local Strip Club with everything paid for you and 2 of your friends.... >>

I paid $100 for the installation and I got a car wash with it. >>

Im sure you got a friend somewhere that can take you to a cheaper place.

call a performance auto shop that specilizies in one area, like a performance shop that works only on suspensions for japanese imports, theres crap loads of them around virginia and they charge almost half of what normal shops would. Example national chain charge something lame like $1000 to swap out all four rotors, performance shop charges only $160

Yes you SHOULD use a spring compressor why would you take that chance?

Secondly, as far as I know its like $50 a spring to change.
