Not the nannies. I drive with TC off and Martin is correct; that's all I have.

'99 aint got no nannies.. weird - those temps are high - min run well under 400

Yeah, but you don't use your brakes that much. You just let the wildlife slow you down

I have a theory, this is only a theory, I have no fact to support this besides experiencing unusually high rear pad wear rate on the '99 996 C2 that I've owned and also on the '99 996 C2 that my brother owned. My theory is this car does have some sort of electronic rear brake intervention built-in but has no switch on the dash to change the threshold of the intervention. I did noticed that when I put a biga$$ TPC front sway bar on which pretty much eliminated corner exit power induced oversteer the rear pad wear rate was significantly reduced.

One way to find out for sure, which I didn't try when I had the car and before putting the bars on, is to check the temp after a session by driving with a one-one thousand mental count before throttling for exit.

Interesting... i do have the "big ass bars" on mine so that could explain and support your theory. the other thing to consider is the rear pad compound. I tried some soft rear brake pads once and they ran much hotter. what compound are you using?

Back when my brother and I ran 996's we used Pagid Orange and then switched to Yellows.

I think that "IF" my theory holds water the type of pads used won't change the temp much if the rear brakes are electronically commanded to drag to reduce slip angle on exit. Which reminded me of a particular incident at which a racer that I know(no name) had his first experience driving an non-manual shifting race car practicing left-foot braking. By lightly resting his left foot on the brake pedal the rear brakes over heated and race pads got consumed in less than one session.

In this "IF" scenario, having an effective limited-slip diff would make a difference as well.

How you go about measuring temps matters greatly in the case of brakes. The temp changes are so fast that numbers don't tend to relate well unless methods are the same to high degree. There might be a big difference in temps but there might be a big difference in sampling methods too. Likely a bit of both.....

Get some data before making any changes. the numbers you see from an IR gun in the paddock isn't going to be very accurate. Use temperature paint on the rotors and the pad backing plate. That stuff can be quite expensive though. Another (much cheaper) option would be temp stickers on the calipers:

GT3 air deflectors that clip onto the lower suspension arm, same as the front ones, get more air in that area, if you want part numbers, let me know ��
