Yes, the braking system is something that shouldn't be bodged or skimped on, but on the flip side I really see a 1k kit as a horrendous waste of money.
It doesn't matter how big or powerful your brakes are, they will only slow the car down as much as the grip in the tyres will permit. Stamp on the pedal at 60-70 on stock disks and pads and you will lock the wheels up. A large braking kit will not slow the car down any faster with exactly the same road and tyre conditions until slower speeds when the stock system has cooked itself. Larger brakes really come into the own at higher speeds when the stock setup cannot lock the wheels up. Larger brake kits are also more efficient, requiring less effort to do the same amount of work meaning they can be abused for far longer before showing any signs of fade.
So, what am I doing? I am planning getting 280mm stock disks and 4 pot calipers off an Nissan 200sx s14a. It'll cost me ~£250 for the disks and calipers and ~£100 for brackets to fit them. They will provide more than enough braking power in a car weighing 860 kilo's with 180 bhp, bearing in mind that the stock brakes on an s14a are sufficient for ~300bhp in a car weighing close to 1200 kilo's. The only concern is that the master cylinder won't have the capacity, which is unlikely given that these 1k kits run on the stock master cylinder. I'd also be as bold as to say that a 280mm flat disk is just as efficient as a 300mm grooved one.
So again, why waste 1k on a kit when £350 will do the same job, leaving more money to spend on other mods? :homer:
