Background As we increase the horsepower and grip in the Lotus, we will eventually find the limit of the stock brake components. Fortunately, the 2-Eleven, Elise, and many of the Exiges are equipped with Lotus branded race quality 2 piston AP calipers. While there's nothing wrong with the calipers themselves, the pistons within the calipers are made from machined aluminum billet. Aluminum has an extremely high thermal conductivity when compared to materials used to manufacture traditional high performance or racing caliper pistons such as titanium and stainless steel. The aluminum pistons are a problem because high friction racing and track-day brake pads get extremely hot. The heat generated in the pad transfers to the steel backing plate of the pad and then to the aluminum pistons in the calipers. The brake fluid is in direct contact with the c
