996 GT2 Brakes
Anyone
For our racer 951 Turbo S, we can get a complete (well) 996 GT2 brake system, at a price of course; the system consists of discs, calipers etc. Just wanted to know if anyone has any experience with this conversion - we know that plenty of brackets will have to be made, but what is the feeling: is this a worthwhile conversion? I tried our friend's 951 racer (which has big reds), and I was not that impressed with the improvement over our own standard brakes. Our standard setup is well-ventilated, has Pagid Orange brake pads, and has sofar performed ok - we are looking at a 100bhp increase soon, so braking will become more important.

Would you not also have to have custom rotors made? Seems like it would be a pain to have that done everytime you need to replace them, plus I cant imagine needing GT2 brakes over Big Reds- just seems overkill to me, and not worth the hastle.

That's what I thought too, but the Big Reds disappointed me, and the GT2 system (with 350mm discs) is as expensive as a four-corner bog red upgrade (in other words, twice as expensive, you'd probably want only the front upgraded to big reds..). so it is attarctive...

There is no such thing as too much braking. I went to 6 titanium piston AP calipers on 14.25 inch rotors on my Rx7. When you have a car that can go 150+ quickly, you want to be able to get down from there as quickly as possible. Whether you're on the street or the track more brake is always good.

It's not the braking power you are paying for, it's the ability to resist fading lap after lap whereas the brake pedal on a stock 86 951 would have gone to the floor long ago.
I think since the stock brakes can lock up the wheels easy at 200kph it's obvious the stock brakes are big enough - the only problem is that they FADE too quickly.
Plus big reds just LOOK cooler!

The brackets should not be any different than Big Red for the calipers, the custom part will be the rotor hats, you'll need to measure to get them custom made and position the rotor at precisely the right offset for the calipers. Go for it - if the parts were available to me I would.

Are you talking about PCCB? don't do it. They crumble under real hard work. Ask on GT2/GT3, you'll se many of them have converted their pccb to the normal steel rotors. The don't stand well at the track, and once you destroy them, the $20,000+ to replace them WONT be fun either. Big reds is plenty. Ask on the GT board though.

Rich,
I think the biggest benefits are not just the lack of fade over time, but the ability to stop without locking up. Bigger brakes and calipers let you brake as hard as smaller brakes without getting close to locking up. Most, if not all, brakes will lock up. The weaker (smaller rotors and calipers) brakes will lock up faster (ie, become useless) than bigger brakes. And, while generally, bigger means better, it is also the quality of the calipers and pistons and master cylinder that effect this. Again, its not just fade that is reduced, but lockup occurs later for any given amount of braking force.

Gordon, lockup occurs when the tire's grip limit is exceeded. Whether the force applied comes from a small brake or big brake, lockup is the same and occurs at the same limit.

No, it is not the PCCB stuff - guess it's the big yellows, so probably the biggest 'conventional' type brakes - they are not that much more expensive than the big reds, that's why I am tempted to get these; just wanted to know if anyone had gone for a similar upgrade before.

It has been done, you need to contact Ian, he is around here (ask on the big board he doesnt come here much). It can certainly be done, he and I talked about it for some time and then he went and did it. The best part of the upgrade is the fact that the calipers are monoblock.
FWIW - it did require custom rotors.

As for the disappointment with the Big Red upgrade, you may want to look at a master cylinder upgrade. My understanding is that the M030 951 includes a larger diameter master cylinder which should increase your perception of brake power.
