Parts spotlight: Miata timing wheel

By

Mazda Motorsports has a new stainless steel timing wheel approved for Spec Miata by both SCCA and NASA that offers several improvements over the previous version, not the least of which are bolt slots cut on the radius, laser-etched timing marks and removing its influence on the harmonic balancer.

“The new product is of much higher quality than the older one,” explains Josh Smith, Mazda Motorsports’ specialist for technical development. “We took a blank-sheet-of-paper approach and really looked at what needed improving. The new one is laser etched. The slotted adjustment holes are all radiused correctly around the center pivot point of the timing wheel, whereas the previous ones were cut diagonally. That was causing fatigue and pressure points on the hardware.”
