Clutch Application Notes
Fits 11, 12 B & B Diaph
12 LS1 Diaph with 100mm Bolts

Use of a stock-style clutch disk with a performance flywheel will often result in insufficient operating clearance between the disc hub and flywheel bolts. Performance and SFI-approved flywheels must be matched with performance clutch discs only. Low head flywheel cap screws are required for all high-performance and racing applications.
