Product Details

The Brembo 4K3.8039AX is a performance Gran Turismo (GT) Big Brake Kit engineered for drivers who demand superior stopping power and fade resistance beyond what factory brake systems can deliver. Brembo is the global leader in high-performance braking technology, supplying systems to Formula 1, MotoGP, and the world's most prestigious automotive manufacturers.

Key Features:

  • 4-Piston Monoblock Caliper Design: Provides consistent, even clamping force across the brake pad surface for improved modulation and feel
  • Axle Kit (AX): Includes components for a complete single-axle installation — calipers, rotors, and hardware
  • High-Carbon Slotted Rotors: Brembo GT rotors feature a high-carbon iron alloy for superior thermal capacity, reduced noise, and extended service life compared to standard cast iron
  • Direct Bolt-On Fitment: Engineered to fit specific vehicle applications with minimal modification for a clean, professional installation
  • Improved Fade Resistance: Designed for sustained high-temperature performance on the street and track
  • Caliper Color Options: Brembo GT calipers are available in iconic red, yellow, and other finishes for a distinctive appearance behind the wheel

Brembo GT Big Brake Kits are a benchmark upgrade for enthusiasts seeking a significant, measurable improvement in braking performance. Each kit is manufactured to OEM-grade tolerances and backed by Brembo's decades of motorsport-derived engineering expertise.

As always great experience. I have ordered from this place in the past and have never had a bad experience. Much appreciation to this company and the people who work there. Thanks again.

I'm waiting on my refund. I was not happy that I couldn't talk to a real person regarding my return and my repurchase of the correct prop that I needed. So , if I get my total refund without a huge restocking fee(since the prop is new in original packaging and I bought another prop that is the correct size) then I will be extremely satisfied.

It's the information I needed for my boat motor. The only issue I had with this maintenance manual was the way the manual was finished. I've worked the the graphic arts industry for 50 years and am well versed in print finishing. The book will no doubt stay together, however there is excessive glue on the spine as the cover wraps around the front/back that distracts from the overall appearance.

Fast

It would have been better if you listed the dimensions so hopefully it fits

Simple and seamless process. Great experience.
