i've heard the exact opposite. i have heard that they will lower your car and HELP your launch greatly. I've heard a lot of people say they run them all the way around and that they hook up almost as well as the eibach drag kit. we put 4cyl springs up front on my buddy's car (nicks 5.0) and his front end shot up like a rocket. we did have springs on the back too, but they are drag springs. in any event, i have heard nothing but good things about them. it seems like too many people run them for them to hurt your launch.
