Twin-disc clutch dicscs 7 1/4" Clutch Masters
 

I swapped to a NASCAR box so I don't need these anymore. They should work with the standard off the shelf twin disc clutch setups: QM, Clutchmasters etc. 7 1/4" diameter. Mazda spline (was used with an FD RX-7 gearbox). Standard friction material (non-organic). These were supplied by Clutch masters but should work with others. Let me know if you need measurements.

Only used for one season of autocross. No measurable wear from new.
