Was thinking of submitting a request to the CRB but wanted to poll this group first. Double-dipping in STL is great, but everyone has read the rules and knows a Spec Miata is not competitive in STL, especially at big races. Not that it would be at the tippy-top of a big T4 field either, but I would think this would be an opportunity for the club to draw more participants toward double-dipping if they knew they had a fighting chance in a 2nd class.
The issues I could see the CRB bringing up are:
1. The T4 camber limit of 3.5 degrees would have to be disregarded if cars are in SM trim. Racers will not compromise SM competitiveness for T4 compliance. The ride height rule shouldn't be a problem.
2. Our minor cylinder head work is technically not T4 compliant. I would think the restrictors cover this gain to bring the benefit to near net zero.
3. The T4 spec weight is 2450. Not too far off what we are now, but it the club would have more success allowing us in complete SM trim rather than requiring double-dippers to swap weight around between every session. T4 cars are allowed programmed ECUs and a cold-air intake.
All this being said, a purpose-built T4 NB should still be more competitive than an NB SM. I think this would still be the case at any track.
What do you all think?
