Michael P - In answer to your question, I pre-traded my 2000 RT/10 in for the SRT. The dealer sold my car in less than a week, so until the new car comes in I am Viperless.
Steve F - The Porsches I spoke about were the club sport editions of the 911 - not the factory race cars like the GT3. These are ordered through the regular dealer network, not through the factory.
Mike Brunton et al. I assume that the two hoops behind the seats are already intended to be roll bars. I just wish that they had made them high enough that they would actually protect me in a roll over crash. If those are not intended to provide protection in a roll over I wish they were not there at all.
As far as asking for a full competition roll cage in the street car, no - I don't believe anyone here has asked for that. I don't get most of the enjoyment from a car like the Viper by driving on the street. Prior to owning a Viper, I enjoyed the MCSCC solo 1 events held at Blackhawk Farms & Gingerman more that any other events I attended, More that autocrosses, and more than track day events with continuous lapping. When I got the Viper, because of the high performance potential, that club required the RT/10 to run with the hardtop in place, and with a 5 point harness installed. Before I had time to modify the interior to allow the harness, I found out about the SRT and because I knew I wanted to trade the RT/10 for it, I didn't want to modify the interior. Because of that I was unable to run those solo 1 events.
What I would hope for in the SRT at this point, as the factory hoops do not appear to be adequate to provide what most independent organizers consider to be sufficient protection, is that a competent aftermarket roll bar manufacturer provide a setup that would be considered sufficient for an otherwise stock Viper be able to run independent organizers solo one and track day events. Although I do enjoy events with Vipers only, I also enjoy running events where a variety of cars can compete together. I just find it more interesting. I do wish that more Vipers would attend this type of event, but locally very few do so.
I apologize in advance if you find my desire for a roll bar that would allow the car to run non wheel to wheel track events without modification to be ridiculous, but I don't understand how a more substantial roll bar would have made the car more difficult to certify in crash testing - had one been planned from the start. Mercedes Benz certainly has considered roll over protection in previous cars such as the SL 500 which had a hydraulic (or electric) pop up roll bar which was tall enough to pass the broomstick test.
