MSA Roll Bar Q

[HorneyMX5]

I built my car to compete in sprints and hillclimbs and by keeping the interior and no wild body mods I assumed I could run in Road Going Series Production class as per the regs in the blue book (would need to remove the boot spoiler for events). Oh how wrong was I? The 2 events I wanted to do this year have supplementary regs to those in the blue book of:

Categories A & B. Road Going Series Production CarsStandard Cars are those as defined by Road Going Series Production in the MSA “Blue Book”, but restricted to 2wd cars using List 1a tyres.Cars are to be to manufacturers original specification, with modifications limited to safety items along with replacement wheels and aftermarket exhausts (not manifolds)No other modifications (body) brakes, suspension, transmission or engine etc will be permitted.

Cars must comply with regulations S.11.1.1 to 11.8.1

No chance of me complying to that. FI, aftermarket manifold, 6 speed box, coilovers, ARBs, Oil Cooler etc etc

This leaves me in Modified Production and that requires as a minimum a 4 point Roll Bar, Harnesses and Seat that are MSA complaint. All good on the Seat front, belts are easily solved but my Roll Bar is a Cusco and the tubing diameter is too small to be complaint. From an afternoon of searching the internet the only one I can find that seems to be compliant is the TR Lane Sprint.

Anyone have experience of this or any alternatives?

There are usually 2 or 3 production classes. The two MSA classes are "roadgoing production" (limited nods) and "modified production" (lots of mods). Many clubs have then added their own "standard" class (very few, if any mods).

The regs you quote are for a standard class. I'd go back and double check that there isn't a class between standard and mod prod.
