ZSM S30Z Hub-centric Ring — Dealer Option Mag Wheels

If your S30Z is running the original Dealer Option Mag wheels and experiencing vibration, worn lug holes are likely the culprit. This is the ZSM hubcentric ring — CAD designed specifically to properly center the original Dealer Option Mag wheels on the S30Z front hub, eliminating vibration caused by worn or oversized lug holes.

This part came about because Taka at Kyusha House reached out on behalf of a customer whose S30Z was suffering from exactly this problem. ZSM designed the ring from scratch, prototyped it in collaboration with Enticed Motorsports (blue prototype) and finalized the production version with RevDev Labs (black). The print quality on the final product is spot on.
