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.

Unlock tighter rear-end control and confidence from your F-Series BMW with the MMX Billet Rear Subframe Bush Insert Kit. These precision-machined cradle inserts limit subframe movement at the factory mounting points to help keep camber and toe stable under load. Expect a more planted feel through fast bends, cleaner power delivery out of corners and a more connected chassis for fast-road and track-day driving.

  • Reduces rear cradle deflection to support the OE rubber bushes
  • Helps maintain rear-wheel alignment during cornering, braking and acceleration
  • Sharper turn-in, improved traction and predictable high-speed stability
  • Precision billet construction engineered for durability
  • Non-permanent upgrade that is fully reversible
  • Quick install with basic tools, typically completed in under an hour

Vehicle compatibility
BMW F-Series F2x and F3x platforms covering:
1 Series and 2 Series F20, F21, F22, F23
3 Series and 4 Series F30, F31, F32, F33, F34, F36

Nforcd knows this MMX upgrade well and it has proven popular with customers looking for a cost-effective suspension improvement without replacing every bush. It pairs brilliantly with performance tyres, coilovers and uprated anti-roll bars for a stronger, more consistent rear axle.
