I have a 93 civic sedan with 18 inch Racing Hart Z5000 with 205/35 tires. I have a problem because only one person can sit in the back without the tires rubbing. Also large bumps and hole in the road casue bottoming out. I know 18s are really too big but the car has the stock engine right now so speed is not going to be increased enough just by putting smaller rims on. My question is what exactly do i need to do in order to stop this? I am pretty sure that just putting stiffer shocks than the factories on it no would stop it. What shocks does anybody recommend, and what shocks could i use from other hondas/acuras that would just bolt up?
