Question: why? Do you have a problem with the rear brakes as they are?
Yes i want to be able to brake later and stop in a shorter distance!!
I have upped performance to 204 bhp and around 320 lb torque and feel like i could do with some extra stopping power
I am a track day addict and dont like being outbraked, decided im going to take the car on track now ive quit racing and sold my race bike.
Soon to upgrade fronts to brembo 4 pots with 323mm discs ... makes sense to also upgrade the rears
My car is only going to get faster as time goes on ..... and turbo sizes increase
The standard rear discs look about the size of a rich tea biscuit and are only just bigger than my alloy wheel centre caps
I think they are all valid reasons for me to upgrade
