Product Description

Upgrade your Audi or Lamborghini’s front braking system with the GiroDisc 380 mm Front Rotors. These premium two-piece floating rotors replace your factory units with a larger diameter rotor (380 mm vs the typical ~365 mm) to deliver increased braking capacity and improved cooling without resorting to an entirely new big-brake kit. Engineered for high performance street and track use, they maintain direct fitment with your OEM calipers while reducing unsprung weight for better suspension feel and sharper response.

Fitment Notes

  • Compatible models: Audi and Lamborghini vehicles which use front brake rotors around ~365 mm diameter and are listed under GiroDisc SKU A1-034 (Audi, Lamborghini 380mm Front Rotors incl spacers & bolts). 

  • Includes caliper spacers and bolts for correct fitment with OEM calipers. 

  • Direct replacement: bolts in to work with factory calipers—no major modification required. 

  • Note: Intended for performance street and track use; check wheel clearance and hub compatibility before ordering.

Included

  • Pair of GiroDisc 380 mm front rotor assemblies (left & right)

  • Caliper spacers and mounting bolts (as specified in the SKU)

  • Floating hat-to-disc hardware (drive pins, washers) integrated into assembly

  • Installation instructions

Product Specs

  • Rotor diameter: 380 mm

  • Material: Floating hat made from US-sourced 6061-T6 aluminum; disc ring made from GiroDisc proprietary high-carbon cast iron.

  • Two-piece floating design: Allows thermal expansion, helps heat dissipation and durability.

  • Approximate weight reduction: Example spec lists ~23.6 lbs vs ~34.5 lbs for stock in a comparable rotor size scenarion.

  • Sold and priced per pair.

Product Features

  • Large Diameter Upgrade: Moving from ~365 mm to 380 mm increases rotor surface area and thermal mass, giving stronger braking potential and better fade resistance.

  • Floating Two-Piece Design: The aluminum hat + iron ring design allows the rotor to manage heat more effectively, reducing warping and improving longevity under high load.

  • Weight & Unsprung Mass Reduction: By using lighter hat material and optimized construction, the system reduces rotational and unsprung weight — improving suspension responsiveness and steering feel.

  • Direct OEM Fitment: Works with existing calipers and uses supplied spacers, meaning minimal fitment hassle and retention of factory brake bias and ABS system calibration.

  • Track-Friendly Cooling: The rotor features curved vane geometry (acting like a centrifugal pump) to channel cooling air through the rotor under load, improving repeat braking performance.
