Lightweight, Long-lasting & Proven! The ULTRAdisc 2-piece rotors are the most proven, long-lasting and lightweight solution on the market. These are the same overall diameter as stock rotors (288mm). They work perfectly with your stock calipers, on and off the track. Back in 2005, Girodisc developed what has become the best 2-piece rotors available for your Lotus.
