I had originally decided on not doing any modifications to the suspension but here I am lol. Ideally, I am looking for coil-over kit that is high quality and durability for regular street use as it is daily driven (I drive around 20K + a year). I understand high quality = more $$ but would rather do it right the first time which is why I have decided to do coilovers vs springs. RS*R coilovers seems to be a popular choice with the 3IS and am also considering them as well but curious to hear members feedback who are running the RR Racing coilover setup.

 

whatever you decide on, make sure the coilovers you choose are rebuildable. metal top mounts are notorious for failing and clunking within ~20-30k miles.
