Product Details

The Brembo Gran Turismo (GT) Brake Kit delivers unmatched performance technology for high-performance street and track applications. This comprehensive upgrade system increases thermal capacity and brake torque through larger calipers and rotors, providing superior stopping power and fade resistance under extreme conditions.

Two-Piece Rotor System Features:

  • High-performance multi-piston calipers (2, 4, 6, or 8 pistons depending on application) with sequentially sized pistons for balanced pressure distribution
  • Two-piece floating hat and rotor assemblies reduce unsprung and rotating weight while improving heat dissipation
  • Drilled or slotted two-piece rotors available up to 16 inches (405mm) for maximum cooling and performance
  • DOT/TÜV approved stainless steel braided brake lines for consistent pedal feel
  • High-performance brake pads engineered for aggressive stopping power
  • Floating anti-rattle disc hardware minimizes noise and vibration
  • Precision-machined billet aluminum caliper mounting brackets
  • Caliper finish options: red, black, or silver powder coat
  • TÜV certification included with most applications

One-Piece Rotor System Features:

  • Cost-effective performance upgrade with 2 or 4 piston calipers featuring sequentially sized pistons
  • Drilled or slotted one-piece rotors up to 14 inches (355mm)
  • DOT/TÜV approved stainless steel braided brake lines
  • High-performance brake pads included
  • Billet aluminum caliper mounting brackets
  • TÜV certification available for most applications
  • Caliper finish options: red, black, or silver powder coat

All Brembo Gran Turismo brake systems are fully compatible with ABS and traction control systems. Complete hardware is included for seamless installation. Proper wheel clearance measurement is critical for fitment—verify wheel dimensions before installation to ensure compatibility with the upgraded brake components.

Best price for the particular part I was ordering. Their staff/customer service is very helpful and polite, but unfortunately their shipping times are lacking. Before ordering on Monday, I called to verify the item was in stock, and asked what shipping method I would need to ensure it would arrive before Saturday. I was told 2nd Day Air. I ordered that same day (around 1pm). The package wasn't shipped until Wednesday evening, AFTER I called and inquired a to why it hasn't moved. What really upset me though was that the package ended up being shipped UPS Ground anyways, to arrive here the very next day. Long story short, I shouldn't have had to pay the extra $20+.

Very fast shipping, lowest prices on the web.

Best price no problem making order. Jesus is Gods gift to those who would believe

Easy to order!

Best price I could find for the brand new name brand product I ordered. Fast shipping as well.
