I was the owner of the silver 2004 NSX in the photos in the original post. I was one of the first users of this setup, I drove it extensively on the track. The performance of the brakes are incredible, very reliable, and cosmetically - they look fantastic. I was a HUGE fan because they had the show quality, yet still had the functionality I demanded.
The parking brake being offered now is a "version 2". The version 1 I was initially testing for Brandon didn't quite meet the muster and had a much larger profile. Brandon worked extensively with WP Pro to come up with the new design which is now offered on the kit. I eventually scrapped the version 1 design and installed the version 2. Installation is very easy, the brake is very reliable. However, of course - you should never lock a parking brake in place on a hot caliper, this holds true with any brake system including factory. So, if you're at the track, don't use it.
Brandon is a top notch vendor. Plenty of communication, very trustworthy, etc. I have pretty high expectations of people, Brandon meets that and the WP Pro system also exceeds my expectations.
Here's a comparison of the WP Pro compared to a "typical" BBK:

Yes, those are the exact wheels I had on my NSX (pictured in the photo). If you purchase wheels with StopTech clearance, you will clear WPPro just fine.
