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.

BMW M5 F90 Suspension Upgrade for Road and Track

Take your F90 M5 to the next level with KW’s flagship Variant 4 tri-adjustable coilover system. This premium height and damping adjustable shock and spring set is engineered for drivers who demand precise chassis control, everyday comfort and repeatable track performance. Perfect for the M5, M5 Competition and M5 CS, it delivers a transformative handling upgrade with crisp steering response, improved traction and a planted, confidence-inspiring ride.

Why enthusiasts choose this kit

  • Three independent damping circuits for true tuning freedom
  • Separate control of rebound, low speed compression and high speed compression
  • Stainless steel struts for long term durability in all UK weather conditions
  • Lightweight aluminium hardware and, depending on vehicle specification, aluminium top mounts supplied by KW
  • Two factory base setups available from KW: Comfort or Performance
  • Proven motorsport-derived technology developed on the Nürburgring 24h
  • Part approval (§19.3) per manufacturer documentation

Fine tuning made simple

  • Rebound: 16 clicks to dial in support, stability and ride compliance
  • Low speed compression: 6 clicks to sharpen body control, turn in and traction
  • High speed compression: 14 clicks to tame bumps, broken surfaces and kerbs

Expect sharper responses, flatter cornering and a smoother, more controlled ride on British B-roads. Our customers consistently praise the balance and adjustability of this damper kit, and we run the same hardware on customer builds with outstanding feedback for fast road use and track days alike.

  • Drivers wanting a serious handling upgrade without sacrificing daily usability
