To answer all your questions. I do have new aftermarket struts by Tockiko(I know it's spelled wrong). I just had an alignment after I put on the coilovers and struts which was like a month and a half ago. And all my tires are new with the correct tire pressure. I always check my tire pressure before I head out to street races on Fridays. I don't know if it is an oversteer/understeer problem. My rear end just likes to get loose and I want something to tighen up the chassis. I have a front upper strut bar and I feel the difference. DEL SOLs(not del slo) have a small wheelbase and they are very loose because of the removeable top. It just seems like I need something to keep the back in check. Someone recommended a spoiler or wing but for some reason I don't want one.
