you will break the stock plates with coil overs you will break aluminum c/c plates with coilovers remember that with coils the entire weight of the car is on the c/c plates, were as before the spring held up the lions share of the weight. the ONLY way to go is to call,run, or browse over to maximum motorsports and have them help you, they know their stuff weather you are goinf for a drag setup or a handling setup, there k members and plates and coilovers are the best in the biz, do not go cheap on this stuff or you will regret it
