My fd runs smooth on straight streets, but on a rough street it's like an earthquake, how can i fix this? It's lowered with rsr coilovers, and it has rims as you can see in my sig.

 

Ditch the coil-overs and aftermarket wheels and go back to a stock base/touring suspension. If the suspension bushings haven't been replaced in over 40k, they probably need replacing.

 

set the coilvers to the higest setting. ride should be better. also don't run a low profile tires.

 

just get springs, they are softer.

 

and how much would it cost me to get springs, and install em?

 

well, if you're going to go that route, you're going to need to put your old shocks back on, or buy some new ones.

shocks will costs you around $450/set (for Tokiko or Koni)
springs will cost you around $100/set

I have no idea how much the stock shocks go for.

You can install them yourself, otherwise it'll probably run about $150-200 for the install.

thx

 

If it's lowered with any coilovers, it's most likely going to be stiff. If you want it to be softer, go back to stock, or switch to tockico with softer springs
