From the beginning there’s been a number of conversations on how good is this system compared to others and I don’t know. If it doesn’t compare exactly as a 996, I would like to know why. Understand a Porsche 996 is a beautiful engineered piece of machinery and can’t be compared to a Pantera of any year. Only way to compare brake systems is place them on a brake dyno. I live in Southern California and StopTech has three brake dynos. Chief engineer there (if he’s still there) used to be a Pantera owner. I’ll look into settings up a test if someone with a different system shares the same interest. Note: Testing to failure normally sacrifices test items.
It's interesting to hear you mention StopTech because I'm using their calipers on my Pantera. Before Wilwood manufactured street versions of their calipers, the main reason to use Porsche, Brembo, Baer, StopTech, etc. calipers was, they had the "DOT required" dust and dirt seals around the pistons, so you could drive the car through a big puddle of muddy, salty water and after years of doing so, the calipers would stand up to it. Now that Wilwood makes weatherproof, "street" calipers, there isn't as much of a benefit to the more expensive Brembo style calipers. That being said, I've never heard of a failure of a Wilwood racing caliper, without dust and dirt seals, even after decades of them being used on daily driven Panteras.
Unfortunately, even with 996TT calipers and rotors, a Pantera won't stop as well as a 996TT. The reasons are: lack of ABS and lack of anti-dive geometry in the front suspension. When you brake hard in a Pantera, the nose drops and the rear rises, which induces weight transfer and reduces traction (and braking potential) at the rear. This effect can be minimized through the careful selection of coil spring rates and shock absorber tuning, but it's nearly impossible to match the Porsche without some anti-dive in the suspension. Then there's the ABS...
