I'm in the UK, let me know if you decide to sell the big reds/discs.

Not sure what you're planning to use but we had good experience with PFC pads as a recommendation. However they are aggressive and do throw a bit of dust which you want to wash off rather than leave.

Im running 996T calipers front and rear, 996T front rotors, 993T rears.
fully admit appearance was part of the appeal. I have all the relative caliper piston and rotor sizes at home and will post later.
my car is an 86 951, so had to upgrade the MC to a 951S unit. Still too much pedal movement for my taste. Car stops fine.

Northern Porker,
Here is the data I have. Apologies but I don't know what the stock brake setup on a 968 is, but I believe you use the same MC as the 88 951S and the 89 951. That means if you go to big, you may have the same issue I do - too much pedal travel. This might a bigger deal for you on the track.
86 turbo brake specs. front calipers 38/36mm, rears are 30/28 front rotors are 298 x 28, rear rotors are 299 x 24
87 turbo brake specs: front calipers 40/36, rears are 30/28 front rotors are 298 x 28, rear rotors are 299 x 24
88-91 turbo (s) details: front calipers 44/36, rears are 30/28 front rotors are 304 x 32, rear rotors are 299 x 24
996T details: front calipers 44/38, rears are 40/36 front rotors are 330 x 34, rear rotors are 322 x 28
The 87 turbos had a bigger MC than the 86s, even for a relatively small increase in front caliper bore size. then the turbo S / late turbos had an even bigger MC than the previous models.

We ran Big Reds on the road/track car for quite a while and they were fine. Once the car started getting a bit too fast (ie racecar with 500hp+ and downforce) we upgraded. I'd say you'll be on the edge depending on certain factors. Ventilation, pads, fluid, duration on track, how many really heavy braking zones on your local track/s.

I am running the 996 TTs in front with the standard 951 calipers in back for the last 12 years. They are a good combination. The car is presently running a 3.1 liter 8v motor, 425 rwhp 450 ft lbs torque at 17 psi. Most of your stopping power is in the front the 951' will still lock up the 315s I am running in back. You will need an adapter for the caliper to fit. If you are running a built 3.0 liter you are pushing at least 400 hp. Heat and fade created by the heat is your big enemy.

Since Porsche changed the caliper between the 993tt and the 996tt I would assume that they made improvements to the caliper. You will definitely require 18-inch rims to run the bigger 996tt calipers.

Isn't the 996tt a monoblock caliper? Pretty sure the 993tt was more or less the same as Big Reds.

Negative, ghost rider. It depends on the adaptor you use, but i am running 996T front caliper under a 17" wheel. It is a tight fit, and I can't put weights on the interior flat part of the wheel. And depending on wheel style, a small spacer is needed. For example, I need a 2mm spacer so my aftermarket cupII wheel spokes dont contact the caliper.
