About Alcon

Alcon for Porsche

Alcon was founded precisely because brakes are not just brakes. As well as being the primary active safety system on any car, the best brakes inspire confidence, augment the joy of driving and reduce lap times far more effectively and affordably than by adding power.And the best brakes are what we make, alongside clutch and pedal box systems for some of the most demanding and discerning Porsche clients on earth

A Quick Look at Alcon

Alcon information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Alcon is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

  • Typical reasons people replace these parts include reducing brake fade on fast-road or track use, and improving pedal feel with stronger, more consistent stopping.
  • Common symptoms include brake fade, cracked or heat-spotted discs, inconsistent pedal feel, and repeated pad glazing.
  • Practical checks/tips: Wheel clearance is critical for brake upgrades—confirm before purchase.
  • Practical checks/tips: Match pads and fluid and bed in correctly, as hardware alone won’t fix fade.

Browse by Category
