Quote:Not a step, but the area inside the bolt holes will only contain 160mm disc (180mm disc is too big w/o drilling new bolt holes). I think it may be raised up 0.13mm when new. But at least with A12 flywheels they are resurfaced flat with no issues

1000 flywheel



Another possibility is since flywheel O.D. is same as the 1200 flywheel, it will fit too. Just would need to make sure a 1200 cover will fit in the transmission case (there are different A12 cover designs some bulkier than others). The A12 flywheel is 3mm thicker so check the clutch action before reinstalling in car (might need to machine the release bearing sleeve down a bit). Or maybe have the A12 flywheel shaved down 2mm?
