740 is cheapest et but its still a lot of money for a set of brakes!
its not... trust me it really is'nt for proper brakes.
My audi brakes are ~£2500 to buy
Brembo 2-piece GT kit using the same GT junior calipers is >£2500 also.
My
ibiza AP's are £1200
what price do you put on proper brakes?
now, if you want some pimprovement, consider grooved disks and performance pads, and high temp brake fluid.. as an intermediate option.
eg: Badger5 grooved 280mm brembo disks, DS2500 brake pads, Motul RBF600 brake fluid.
You can then drive em to this extreme and not have any clue inside the car how hard they're actually working... perfect pedal and stopping still!!!
