ive bidded on two of them and lost,but offered me one for 140 quid, i emailed them before i purchased asking about the power rating of it, and they replied 'our clutches are rated up to 200bhp' you will need a paddle clutch with my spec,

ive got their organic stage one clutch in at the mo, and slips in 4th when warm, so be carefull!

might try one though as they are 100 quid cheaper on ebay than their website!
