Product Description

The EBC RK1034 rear brake rotors are direct OE-style replacements designed for Lexus models including GS300, GS400, GS430 (1998-2005), IS300 (2001-2005), and SC430 (2002-2010). Made from high-grade G3000 grey iron and finished in Thermic/GEOMET™ silver-grey coating, these rotors resist corrosion and require no prep before installation.

Precision machined and balanced in the UK to strict ISO/QS standards, each rotor undergoes 100% run-out inspection to deliver smooth, vibration-free braking. Featuring factory-spec dimensions - 308 mm diameter, 64 mm height, 5x114.3 mm bolt pattern, and 62 mm bore - the RK1034 ensures exact fitment with stock calipers and FMSI D771 pads.

Ideal for daily commuting and luxury driving, the solid design restores original stopping performance and ride quality. Street-legal and backed by a 12-month/10,000-mile warranty. Replace both rear rotors together for optimal braking balance and longevity.
