Applications:

1999-2006 BMW M3 [E46]

Benefits:

Looks Awesome and Gives your M3 that ""SUPERCAR"" look

Balanced Brake Upgrades with optimum brake bias offer the shortest stopping distance with the best pedal feel

StopTech Brakes offer shorter stopping distances, better modulation, firmer pedal feel and less fade than competitors

StopTech's AeroRotors® offer the best airflow available, delivering better cooling, less fade and longer rotor and pad life than competitors

Featuring the STIFFEST Calipers on the market, StopTech's calipers offer superior clamping under hard braking than any other caliper on the market

The Benefits of a Big Brake Kit

A StopTech Big Brake Kit BMW E46 M3 give your vehicle that Supercar look and feel, and exceed stock performance in two areas - thermal transfer . First, larger rotors increase heat capacity. Second, stiffer calipers and stainless steel lines reduce unwanted flex in the brake system, resulting in superior pedal feel and performance.

The key, however, is to increase heat capacity and reduce compliance without upsetting the stock front to rear brake torque ratio. If the brake upgrade you select adds too much front torque (as many do), you reduce your car's ability to utilize the tractive capacity of all of the tires to the maximum practical extent (even on ABS equipped cars) and you therefore create performance sacrifices. In addition, too many pistons or pistons that are too large will make the brake pedal much more difficult to modulate, which limits a driver's control of brake input on the race track. That's why StopTech has taken great pains to develop a system that keeps the brake force balanced.

StopTech now offers an anti-corrosion gold zinc coating for all AeroRotors. The coating benefits customers who live in cold climates where snow and road salt are commonly encountered, and customers who would prefer to not have visible surface rust on the vanes and outer circumference of their rotors. Zinc coating does not have a negative environmental impact like other coatings. Gold zinc coating costs $70 per axle extra.
