Right ive reasearced clutches and asked questions for ages, not only am i not 100% sure which one i need im also having trouble finding these clutches in uk, ive found a place in the uk that does exedy for an ok price. I have selected 2, the exedy single plate organic race clutch or, Exedy Single Plate Cerametallic Race Clutch sprung 3 puck. Im running a b18c4 stock at the moment and will be turboing with a full race stage 1 in the future. if i get the organic im worried it will not be up to the job in the future and if i get the cerametallic im worried it will be too harsh on the gearbox etc. any advice and info on the exedy cerametallic would be great thanks
