I recently purchased a lowering kit from Eibach and I was wondering something. I know this might be a silly question, but do I also need to replace the shocks while I install the lowering kit? And if so, do I have to buy a special shock for a lowered vehicle or can I go OEM? BTW, the drop is 1.5" front and rear. Please let me know so I can make the proper preparations for lowering my car, thank you!
