Fitment Notes

• Fits vehicles equipped with standard cast iron OE rear rotors only — does not fit vehicles equipped with factory Carbon Ceramic (CCB) brake packages
• Designed for use with Brembo rear calipers as originally equipped on these platforms
• Audi R8 MK1 V8 4.2L production ended after 2015 model year; V10 5.2L continued into MK2 (2016+) as the sole engine option
• Lamborghini Gallardo production ended in 2014; no further model years apply

Features

• Fully-floating 2-piece rotor design using EBC's patented SD-Drive stainless-steel bobbin system, allowing the outer friction ring to expand and contract freely by up to 3mm under extreme braking heat
• Outer friction rings cast from high-copper, high-carbon G3500 disc alloy for outstanding resistance to wear, cracking, and thermal fatigue under track conditions
• Aerospace-grade aluminium bell (hub) precision-machined and hard-anodised for corrosion resistance, visual appeal, and long-term durability
• All bobbins machined from a single piece of stainless steel — prevents corrosion and ensures smooth floating action throughout the rotor's service life
• Anti-rattle spring clips at each bobbin location eliminate off-brake disc rattle, making these rotors completely silent in normal street driving
• 48 curved vanes per disc — handed left and right — to maximize airflow and cooling efficiency in the correct rotational direction
• Swept-groove (slotted) friction surface continuously deglazes brake pad material for consistent, fade-resistant braking performance on road and track
• Significant unsprung rotational mass reduction versus equivalent solid cast iron rotors, improving steering turn-in response, tyre contact, fuel efficiency, and wheel-to-ground power delivery
• Replaceable outer ring design — when the cast iron friction ring wears out, only the ring needs replacing; the aluminium hub and stainless bobbins are reused, reducing long-term ownership costs
• Designed, manufactured, and run-out tested in the United Kingdom to strict dimensional tolerances

Specifications

• Position: Rear axle (left and right)
• Rotor Diameter: 356mm (14.02")

Product Description

The EBC SG2F018 is a pair of fully-floating 2-piece rear brake rotors engineered specifically for the Audi R8 (MK1 and MK2) and Lamborghini Gallardo — high-performance supercar platforms where braking demands are extreme and thermal management is critical. Unlike conventional solid cast iron discs, the SG2F018 uses EBC's patented SD-Drive bobbin system to mount a swept-groove cast iron friction ring onto a hard-anodised aerospace aluminium bell. This floating architecture allows the outer ring to expand radially by up to 3mm under the intense heat generated during aggressive driving or track sessions, eliminating the warping and cracking that plagues fixed one-piece designs. The result is a rotor that delivers consistent, linear braking performance lap after lap without the thermal distortion that causes pedal pulsation and uneven pad wear.

EBC's SG2F 2-piece rotors are designed either as a direct OE replacement for vehicles already equipped with factory 2-piece rotors, or as a bolt-on floating conversion for cars that originally came with solid cast iron discs — in either case, no vehicle modifications are required. The swept-groove slotted surface continuously wipes and deglazes pad material to maintain a consistent friction interface, while 48 curved directional vanes (handed left and right) draw heat away from the friction face efficiently at speed. Bobbins machined from single-piece billet stainless steel resist corrosion over years of wet-weather use, and anti-rattle spring clips at each bobbin location ensure the discs remain completely silent when the brakes are released — a critical consideration for a vehicle used on public roads as well as the track.

Beyond braking performance, the SG2F018 delivers a meaningful reduction in unsprung rotational mass compared to equivalent solid rotors, which translates directly to sharper steering response, improved tyre contact with the road surface, and more efficient power delivery to the wheels. For owners who track their R8 or Gallardo regularly, the replaceable outer ring design is a key long-term cost advantage: when the cast iron friction surface eventually wears out, only the ring is replaced — the precision aluminium hub and stainless bobbins are reused indefinitely. Every rotor in the SG2F series is designed, manufactured, and run-out tested in the UK to exacting dimensional tolerances before leaving the factory.
