Re: Brakes (Mov\'it)?
The Desert Venom Race Team has been running the brake system from Mov'it since 1998. It's also known as the Porsche "Big Red" system. We have had great experience with the system and highly recommend it (btw, we are not sponsored by Mov'it, nor do we receive endorsement fess, favors, or anything else like it)!
This is the same brake rotor and caliper that comes on the Porsche Twin Turbo. It features 13" rotors and 4-piston calipers in both front and rear. These fit easily under John Purner's 17" or 18" race wheels. You can also get the more current brake system that Porsche puts on their GT3 car. I believe you need 18" wheels for that application because the rotors are 14".
The system we use (not the GT3 system) comes with specially machined caliper mounting brackets that provide for direct bolt-on to your existing knuckles. It does require that one of the "ears" on each knuckle be removed (cut off). This is a sim-ple process that takes less than 5 minutes with a decent cutting wheel.
The front rotors come with removable hats that are replaced on every 3rd rotor change. The replacement cost is $225 per hat (two in total). The front rotors can be purchased from any Porsche dealer and cost about $210 each. The rear rotors are machined differently and come from Germany. The hats are "built-in" and do not require replacement. Each rear rotor cost about $250 including shipping. We replace the front rotors about once every 30 track days and the rear rotors about once every 60 track days. We have found this to be a very inexpensive operating system.
You do not need to change your brake master cylinder or your pedal assembly. You do not need a proportioning valve. The system is extremely well-balanced for the Viper.
We have found the Pagid race pads to provide an excellent balance of performance versus wear. We use black pads on the front and orange on the rear. It depends on the track, but normally we change front pads about once every 10 track days and rear pads about once every 20 track days. The front pads are about $210 per set ($105 per wheel), and the rear pads are about $170 per set.
The upfront cost of the complete system, which includes front rotors and hats, rear rotors, calipers, caliper mounting brackets, stainless lines, all mounting hardware, including emergency brake mouning brackets is about $5500.
This is an extremely effective system in terms of performance and cost. It also has several years of track proven experience on Vipers. This system is found on no less than 10 of the Viper Days wheel to wheel race Vipers.
One other important thing...this system does not create so much heat that it destroys other components inside the wheel well. For the first three years I ran this system with no brake ducts whatsoever. The little Porsche air deflectors which can be purchased for about $10 each from your Porsche dealer is all you really need.

My only disappointment is that they do not provide sponsorship dollars for the Viper Days series. Thanks to Stop Tech and other brake companies for their support of VCA racing!
