SPAX SUS KIT
honestly! trust me, ive driven my m8s identical car to mine on 35mm PIs and mine is MUCCCCCH better. his is even stiffer than mine but mine gives u less understeer as it still absorbs the lil bumps, whereas his just bounces over the bumps!
not saying ull regret it, but id advise gettin a FULL kit *£268 mine was
