ARP Mazda Miata Crank Pulley Bolts

A common problem with Spec Miata racecars is the crank pulleys coming loose because of the OEM 10mm bolts breaking as the engine is often bounding off the rev-limiter. These Properly sized bolts will replace the OEM bolts and are more suitable to the stresses of circuit racing or drifting where the rev limiter is often hit.
