Up until 2003, all cars where required to use drum brakes from the 1200cc or 1300cc VW. From 2003 onwards, disk brakes of any make are allowed, provided that they utilise single piston callipers, non cross drilled and non ventilated rotors, and comply with the minimum weight per assembly. Any brake pad compound is permitted. Most new cars are built with disk brakes, and some older cars have been upgraded to disk brakes at a cost of approximately $1500 depending on the brakes used, however there is very little performance difference between disk brakes and drum brakes, and cars with both can race competitively together.
