the best coilovers out there are either Ohlins or Moton
take your pick
they run in the area of $12,000 - $15,000 for the set
and they are the shit
if your just looking to slam your CRX to the ground then you do not need the best coilovers
hell you dont even need good coilovers
i already know you arent planning to corner balance the car and properly tune your suspension... and even if you did, with the car slammed to yhe ground like that your suspension geometry will be so fucked up regardless of what coilovers you got best or worst your car is still going to ride and handle like shit
you might as well cut the springs
if you want your car sitting on the ground then i agree with nick, just get air bags and be done with it... at least then youll be able to make it over speed bumps and shit
