My conversion uses the Dave Mac shafts and a custom lightweight flywheel mated with a helix 6 paddle single plate clutch. It cost me around £1300 including the purchase of the box and cables etc.

It sounds alot and is....but I know that it won't break. You could try and make your own shafts, cut and weld them etc but would you be replacing them after a short time of abuse?I don't know but can't afford to find out.

Speak to Luca, Simon at Sitech Racing etc. They have run cars with this conversion done for a long time and other than Luca's box casing break there hasn't been a failure of the cluych, flywheel or shafts(if I'm wrong let me know!)
