I have a Helix organic clutch and matching single mass flywheel for sale. Removed from my car after 8.5k as it's quite heavy and I need my car for a lot of commuting now. Few heat spots but surfaces are completely smooth. £450 + delivery! Any questions just ask.
Just outside Nuneaton mate. The flywheel is a helix lightened steel sm. It all came in a matched kit. HF 9229 IIRC. Will check my paperwork when i get home this evening Fits r26 & r26r. Just make sure the slave cylinder is the new version with metal piping as the old plastic pipe one can't take the strain.
Paperwork just says "Helix Organic Clutch and S teel Lightweight Flywheel Kit" so no specifics but can email ED to check the exact version if you like? There's no markings on the flywheel either from what I can see. Friction plate is exactly 8mm thick No release bearing unfortunately
