this,
the 312mm non racing brake upgrade is awesome value, it uses the bigger calipers off the leon.
the 312 porsche upgrade uses 4 pot beasty brakes from a carrera and is beast
the 343mm R32 brake upgrade uses mk4 R32 brakes, (robbies got a set cheap atm)
the 323mm LCR brembo upgrade is what i have on mine, and is probably the best brake setup for a boc, i can plant my foot wherever and it will stop. not cheap but so worth it.
all of them are a HUGE upgrade over stock, the 288s are pony, not worth using, just upgrade to any of the above you will not regret it.
