The test was called, “Tire rapid deflation”. In a nut shell you drive the vehicle going 60 mph over some really large spikes that are welded to a big plate that is bolted to the track surface (see photo). Preference is to do the right side as the spikes pass under the drives seat. You spike the tires and bring the vehicle to a controlled stop. Had run this test about 3 times but we needed to do it one more time, as we released a new tire construction. The test was conducted at our Michigan Proving Grounds (MPG), Jeff Walsh was the driver. Well Jeff hit the spikes with the right front tire, but the spikes were bigger that what we used before (all previous testing was done at our APG Yuca track). The spikes went through the tire through the right front rim and proceeded to rip the plate out of the track. The plate kicked up under the car and propelled the car skyward. The car came down hard and upright but it hurt the right front pretty bad not to mention the bottom of the car is banged up. Dennis Breitenbach would know the extent of the damage as this was his baby for the entire life of the program. My Ride and Handling engineers gave Dennis a detail model of CP4 at the end of the program for all his work on her. That being said, CP4 was THE Ride and Handling car for the program. It was the first GT to get to 200 mph (Jeff Walsh @ MPG). It is a very significant car from the program and I hope someone from the forum gets it and has it repaired. I just want to make sure that everyone on the GT Forum knows what they are getting before they bid. Would love to see it back on the track as this car is tied in my book with CP15. Being a CP it is not a street legal vehicle.
