lol setup for a v8 supercar is around the 12k mark, the 20k part would be the extra pads,as the brembo 12 spoters use 4 pads and are around $1000 a set. the soft pads dont last long at all,but fluck me they stop well from 300km/h.even with a lightcar{1125kg}and brembo 12spots,you can loose brakes through heat.
