The M3 sedan and its coupe sibling, the M4, continue the tradition of M by offering blistering performance and unparalleled driver feel in a slick, hi-tech, modern package. For serious drivers of the M3 or M4 who want to go beyond what BMW offers out of the box, Sparta Evolution presents their big brake system for the F8x M3 and M4.

While the factory brakes are quite adequate, they are not exactly ideal for race track. Sparta Evolution’s Triton braking system addresses these issues to create a set of brakes that not only feel better, but are also able to withstand the conditions of hard track driving.
Sparta Evolution starts with lightweight forged aluminum calipers and American made Pegasus brake rotors for durability. The calipers are held together by a set of ARP aircraft grade hardware, a first for the industry, and feature a clever quick-release pin for fast and speedy pad changes. Sparta Evolution’s Triton caliper design utilizes a standard FMSI pad shape so pad choices are not restricted.
In addition, the Triton caliper can be offered in different caliper and piston sizes, ranging from the small 4 ventilated pistons to the larger 6 ventilated pistons for added stopping torque and brake fade resistance. For added durability, the calipers are also finished in an anodized coating that is not only more durable, but also weighs less than a traditional powder coat.
Sparta Evolution Pegasus rotors come standard in a free floating two-piece design, front and rear. All rotor hats are and are anodized in a standard black and machined from forged billet aluminum to ensure strength and lightness. Sparta Evolution’s Pegasus rotors feature a unique s-groove pattern that provide a constant leading edge and assist in developing initial bite of the pad, their ability to channel away off gassing vapors provides more consistent control of brake torque at a variety of temperatures.
Included in the kit is a set of Goodridge brake lines, which in conjunction with the new cooling capability of the rotor and caliper makes for stellar brake feel and highly consistent braking, even under extreme conditions.
Brakes shown on the Black Sapphire M3 are a set of Sparta Evolution Triton TS260X 6 piston calipers in Machine Silver with 380mm Pegasus rotors for the front. The rears receive the Triton TS240X 4 piston calipers also in Machine Silver with 380mm Pegasus rotors.
The Austin Yellow M4 features Stealth Gray Sparta Evolution Triton TS260X 6 piston calipers with 380mm Pegasus rotors up front.
For its rear, it gets the Triton TS240X 4 piston calipers also in Stealth Gray with 380mm Pegasus rotors.
