Hi Guys, i am at looking to get someone to test brake pad product in a 911 Porsche, am i right in assuming that the 997 GT3 would be the best option to take to a test day?
I am wanting someone to test our RC6E (endurance) compound.
This pad is also very similar to the 996 GT2/GT3 cup pad from my dimension chart.

Team Parker racing have a gt3 cup in the series might be worth asking them

We will be running a number of track days with a decent cross section of drivers in our 997 GT3 Cup........
