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 sharper steering and front-end precision for your BMW roadster or Toyota coupe with this premium Dinan upper chassis brace set. Designed for the G29 platform and also suitable for A9x GR Supra, this front shock tower bar upgrade delivers a noticeable increase in stiffness, more confident turn-in and a cleaner, more purposeful engine bay.

Our workshop has installed these on customer G29 Z4 sDrive30i and M40i builds, as well as A90 and A91 projects, and the feedback is consistently positive. Expect tighter response, improved consistency through fast direction changes and a more connected feel on B-roads and track days alike. It also replaces the unsightly flattened factory cross tubes with a beautifully finished solution that looks as good as it performs.

  • Engineered rigidity: minimises strut tower deflection to help maintain geometry under load
  • More direct steering feel: crisper initial response and predictable front-end grip
  • Beautiful finish: black anodised billet aluminium for strength, low weight and an OEM-plus look
  • Intake friendly: compatible with the standard airbox and most performance intakes that retain OE clearances
  • Quick, clean fit: direct bolt-on with no cutting; Z4 applications re-use factory fasteners
