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.

Transform the back end of your BMW 1 Series M135i F20 F21 with this stealthy matte black rear aero fin kit. Designed specifically for 2011 to 2015 models, these lower bumper blades deliver a sharper, more aggressive look with an instant motorsport vibe. Quick styling upgrade, big visual payoff, zero hassle.

Each fin hooks neatly over the inner edge of the factory lower valance, so there is no need to remove the original part. High-tack double-sided adhesive comes pre-applied for a clean, straightforward install. If you want belt-and-braces security, the fins can also be mechanically fixed after positioning.

  • Vehicle specific for BMW M135i F20 and F21 2011-2015
  • Set of four rear aero blades for the lower bumper area
  • Matte black finish for an OEM-plus appearance
  • Pre-applied strong adhesive for a quick, tidy fit
  • Hook-over design adds extra support on the inner edge
  • No removal of the standard rear valance required
  • Optional drilling possible for added reinforcement

We have fitted these on customer cars and the feedback is consistently positive: fast to install, subtle yet purposeful, and a great way to elevate the rear profile without replacing the whole lower section.

What you get: four fins with high-strength adhesive pre-installed, ready to mount.
