hey all, does anyone have any experience of the underdrive pulley sets (Neuspeed and Unorthodox Racing). I'm doing a Mk2 Vr6 conversion and i heard somewhere that by using these pulley sets you don't need to dent the chassis leg, any truth?? any benefits? can you use them on a relatively standard engine (Induction kit, 6 branch + de-cat). any comments welcomed. Cheers, James
