A number of users had issues with roadmagnets initially which led them to try and make new springs. They ended up keeping the same design and shipping out rear isolators from the 8th gen si to make them work.
if you drop the car more than 2-3 inches it will throw it off and you might notice more tire wear than normal so you most likley need a camber kit .Im thinking about going with the Tein Street Advance coilovers as ive heard of issues from some of the other products mentioned. I was just wondering if anyone has gone with that setup yet?? I want the car to ride nice and be completely practicle for daily use. Having said that raises my next question, does tein offer a camber kit or will just about anyone work nomatter the kit I use? I dont wanna eat tires.
