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.

SPEC BMW E82 E90 N54 N55 SPEC-Design Clutches for 135i, 335i and 335d

Upgrade your BMW N54 or N55 clutch with a proven SPEC-Design performance clutch kit. Ideal for BMW 135i and BMW 335i, and listed for 335d applications, these SPEC clutches deliver higher clamp load, faster revs and confident power delivery for fast road and track use. We have used these kits ourselves on Nforcd builds, and feedback from our customers has been excellent for drivability and reliability.

Why choose a SPEC-Design clutch for your BMW N54 N55

  • Non-SAC mechanism pressure plate for consistent pedal feel, stronger clamping force and improved engagement
  • Lighter rotating assembly for quicker throttle response and higher rpm capability
  • Designed to work with SPEC’s billet rebuildable flywheel for long-term serviceability
  • Billet aluminium flywheel option at 14 lbs, or billet steel flywheel at 22 lbs
  • Multiple stages to match your build, from fast road to high power performance

Important fitment note: these SPEC-Design clutches require a billet rebuildable flywheel and cannot be fitted to an OEM design flywheel. If you need an OEM-fit solution, contact us and we will advise the correct kit.

Pairing recommendation: we recommend the SPEC BMW billet rebuildable flywheel when installing this clutch kit.
