The Brembo kit with a special color is just over $3K ($3300 IIRC). I had these on my car and loved them. The nice thing is that a) they are floating rotors with the Mclaren buttons so no noise b) the brake caliper with pad and rotor is almost 10 lbs less a side than the current Big Red setup on the front.
The preferred method of brake upgrading to go to at least the RS rear caliper for better brake balance. I had this setup and it was AWESOME. You can also get these painted at the same time as the fronts so they will match perfectly
Jim Morton had a nice write up on this not too long ago.

At $3300 and 10lbs less each corner, looks like a decent deal. I am really trying to resist, I am not convinced about the upside of bigger rotors for my needs, but I do like the unsprung weight savings upside.

Quote for Q45/911: (I don't know how to do real quotes):
"Sorry, I should have realized how tight your budget was WHEN YOU BOUGHT A RUF WHILE YOU STILL HAD A TT!!!"
1). Errrr.... it was an accident.
2). The devil made me do it.
3). I lapsed into lunacy... have not yet returned.
4). Thank gawd for big lines of credit.
5). Actually only had the two of them in my garage for less than a week.
6). My kids don't need no college education.

Up the power and heat and transfer more power to the front (which can only turn or apply power at the same time) and you do not have an optimal situation....
I don't think the TT is the type of car that you try to turn and power up at the same time; its much more of a point and shoot car; like most high torque cars.
Yes? No?
And, I have to agree that the only reason more race cars don't have AWD is because it has been shown to be a huge advantage (Audi showed that about 15 years ago) so it not allowed.
I'm not convinced the 2wd conversion is such a hot idea...

After doing it Pete, and having numerous customers I can tell you it is. The Porsche drive system is not an intelligent system. As you make more power, it just sends more power forward. The whole vehicle dynamics thing comes into place with the turning wheels trying to also be drive wheels. It doesn't work. The push (as in front wheel drive car as you may be sending 100+Hp up front) just gets worse. You can not just balalnce it out with tires and suspension settings.

I'd have to drive a 2wd car before it makes sense to me. Given that the system is supposed only transfer 5% of the torque to the fronts under normal traction conditions, I don't see why adding over 500HP should make such a big difference. The only time more power should be going to the fronts is when the rears are loosing traction. How can it be a bad think for the power to transfer to the fronts in that condition. Why is anyone turning the wheel in that condition? Turn-in shouldn't be under a lot of throttle?!
Is it simply that it is more fun to slide the rear around in corners? I can understand that. But to achieve fastest possible lap times, even with 600HP it should still be better to have AWD.
Still doesn't make sense to me...

The Quaifes made a huge difference in traction, but the car has some pretty wicked torque steer at times due to the front tires really working to pull the car forward. The grip out of corners is astounding now and the car goes exactly where I point it with no understeer. The toughest tihng to adjust has been the driving, it just seems surreal how much power I can put down mid-corner.
Maybe we should look to get something like this for our 993's rather than giving up on AWD?
