Front Brake Upgrade Kit for 78-86 Cars


this part is Pikes Peak tested

Application : Porsche® 928 78-81 Base Model and 928 S-types from 1982-86. This kit will upgrade these cars to S4 brakes.

Background: Some of the first feedback about the Porsche® 928 was that it was under-braked for a car of its weight and performance characteristics. Porsche® ultimately corrected this when they developed the S4 brake system with their 4-piston, large-rotor setup in 1987.

The difference in braking performance and stopping distances between the early setup and the S4 brakes is AMAZING.

What is Included: Optional Used Parts that you will need:
  • A pair of used front brake calipers from a 928 S4 or GT
  • If you have a 928 "S", you will also need to find a pair of used front spindles from a 1978-1980 non-S car.

The Bonus: Every brake upgrade kit we sell comes with a complete replacement set of front and rear stainless steel braided brake lines. Braided stainless brake lines will give you the firmest brake pedal you have ever felt - and the piece-of-mind that your flexible brake lines are new, and abrasion and cut resistant.

Fitment Notes:
  1. If you are not sure whether this kit fits your 928, call us, we can help.
  2. These are bigger brakes and rotors. Some (not all) early "phone dial" wheels will not fit over the new calipers without a small wheel spacer. If needed, the spacer can be purchased from us here.
