zerothread?id=219919but you wont find anything about the suspension in there, plus its still not complete. soon tho you've already looked in the best place to find info on the M30, f31club. you will find all you need to know there because there is no direct replacement coilovers YOU have to make that shnit fit. the S series car weighs significantly less then the M so the suspension isnt designed for the M but the chasis is close enough to make it fit. this car is going to require custom modification, because it is not a tuner like a honda where you go to pep boys and buy parts of the shelf if your going to buy the car as a project you will have to make everything fit yourself or pay alot of money to to have someone do it. if you cant do custom work yourself then i suggest you buy a honda civic.
