Product Details

The Brembo Gran Turismo (GT) 4-Piston Big Brake Kit is engineered specifically for the 1987-1991 BMW E30 M3, delivering exceptional stopping power for both daily driving and high-performance street and track applications. This comprehensive front brake upgrade features 330x28mm 1-piece drilled and vented rotors paired with Brembo's proven 4-piston fixed aluminum calipers in a black finish.

Complete Brake System Package Includes:

  • 4-piston fixed aluminum calipers in black finish
  • 330mm x 28mm 1-piece drilled and vented brake rotors
  • High-performance brake pads
  • Stainless steel braided brake lines
  • Aircraft-quality mounting brackets and hardware

Key Features:

  • Direct bolt-on installation using original suspension mounting points
  • Fully compatible with stock brake master cylinder and ABS systems
  • Cross-drilled rotors feature bi-angle chamfering to reduce stress cracking under high-temperature operation
  • Corrosion-resistant rotor coating eliminates rust and provides aggressive appearance through wheel spokes
  • Fixed caliper design ensures consistent pad wear and superior modulation
  • Significantly larger rotor diameter increases thermal capacity and braking torque

This front brake system dramatically improves braking performance over the factory setup while maintaining excellent pedal feel and ABS functionality. The drilled rotor surface helps dissipate heat and gases during aggressive braking, while the corrosion-resistant coating keeps the rotors looking great between the spokes of your wheels.

Important Installation Notes:

  • Requires minor modification for installation
  • Wheel clearance verification is critical—measure your wheels before ordering to ensure proper fitment with the larger calipers and rotors
  • Professional installation recommended

Brembo Gran Turismo systems represent the perfect balance of performance, reliability, and value for enthusiasts seeking track-capable braking without the complexity of full racing brake systems.

<br><br>Borgeson 000940<br><br>I found Autoplicity during a price search on the Borgeson steering shaft for my truck. I had never heard of them, and was a bit skepticle. But after doing some research, found that Autoplicity has a good reputation on a Jeep forum I visit.<br><br>I decided to order, and I am impresed. Extremely fast shipping, I placed my order on Saturday, and its now Monday before noon. I am holding the new part!

excellent service, i had to wait a few days for the order to be processesed, but only because i ordered on Friday afternoon, but love the site!

Great prices and fast shipping. What more are you looking for?

This was my first purchase from Autoplicity, and it was an excellent experience. They had the Motive brake bleeder adapter I needed at the best price I could find on the web. Shipping was prompt and the transaction was super smooth. Thanks!

Shipped out fast. Prices are very competitive. Couldn't ask for more.

good so far

SO HAPPY! I have to admit, I was hesitant because I had never heard of autoplicity and there wasn't item a picture up for the Thule T2 rack I bought, but wow am I happy. Autopliicity had it for $100 less than other sites and the shipper was Amazon prime fast!!! Definitely a happy customer!!!!
