Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Protect your BMW investment with a proven crankshaft bolt locking solution that prevents timing drift and safeguards your engine from costly damage.

This MMX Performance bolt capture plate is a precision locking plate that clamps over the factory fastener head on the front of the crank. By physically preventing rotation of the OE fastener, it stops loosening under torsional vibration and pulsing loads, helping to eliminate timing movement and the associated risk of catastrophic failure. The elongated mounting slots make alignment straightforward for a consistent, secure installation every time. Designed to work with the MMX one-piece hub or the original hub, it is the ideal reliability upgrade for both road and track cars.

At MJ Modifications we have installed this upgrade on customer cars and our own builds. Feedback has been excellent, with owners praising the peace of mind, the straightforward fitment, and the confidence to drive hard without worrying about crank fastener movement.
