Flywheel and flexplate bolts play an important role in the performance and safety of both street and race cars, which is why the fastener experts at ARP developed bolts far superior to OE hardware. Forged from aerospace alloy and heat-treated prior to thread rolling and machining, both series feature a flat 12-point head design and larger-than-stock shank for improved strength and flywheel register. The premium grade Pro Series has a 190,000 psi.
We strongly advice to use new flywheel bolts after refitting the Lotus flywheel
