I did a search on the topic, but couldn't find an answer to this question. Are removable door bars permissible for Production cars? I'm itching to start building a turbodiesel powered '87 Mercedes 190D 2.5 Turbo to run at Bonneville. This is a 4-door "baby benz". It's been a lifelong dream for me (I'm about to turn 40 years old). I want to be realistic and try to get into the USFRA 130 club, then work towards the 150 club, then eventually into full scale SCTA racing (production supercharged class I believe).
I do not expect to break a record with this car (the existing record is well over 200 mph now), but I'd like to earn some diesel / biodiesel / veggie-oil powered braggin rights.
Anyway, as I look at the design of the car and the required cage, I can see that a removable door bar would be advantageous with the 4-door configuration. I believe it would be OK for the 130 and 150 clubs, but how about in the Big Leagues of SCTA? With the 4-door configuration, the main hoop would have to be behind the front door opening, as opposed to in-line with the door opening as on most 2-door cars. The smaller door opening makes for more difficulty with respect to entry and exit to the car, so the removable door bar would allow a little more ease of entry/exit.
Thanks for providing a great forum, and I look forward to my first Bonneville trip.
