So i have some springs that will slam my car on it's nuts. but i am wondering if that will mess up my TEMS or would it be ok to put the springs on? or would it be better to shop around for better springs or even adjustable coil overs?
Springs have nothing to do with Tems. its dampening in the strut. With super low springs you bottom out your struts and likely ruin them in a very short amount of time. Get a QUALITY set of coilovers and be done and happy with it.
