Yes, they fit. They don't fit properly though, the front ones have to been turned upside down which is dangerous imo. Back ones fit fine, but aren't designed for the weight of the car! They'll lower a C around 60-70mm, and going that low on standard shocks will knacker them.
i was thinking of gettin B springs, but aftet the debate on here and chances of ****ing my shocks i think ill keep to apex, with 40mm is it still easy enough to fit the jack under the car etc? i know you have problems with b's?
