MSA rules for composite roofs

Does anybody know or where I would find the rules and regs regarding composite roofs and weather they are aloud or not.

Thanks
Alex

 

Blue book. Doubt they have a safety case against them

Is there much weight to be gained with a composite roof?

I'm doing a mk1 at the minute and I can't see there being much weight to save if any. The roof skin is thin and I've cut the cut supports out.

 

Mine is skinned in 1.2mm ali, but that's just me..........

If caterhams can race can't see what a caged car with composite roof can't

 

This what the MSA have said.

Hi Alex, There is no restriction in Circuit Racing, however we suggest you check your championship regulations as they may further restrict. For Sprint and Hill Climb events, regulations S11.4.1 and S12.5.2 prohibit changing the material of the roof panel in the Roadgoing Series Production and Modified Series Production categories. Kind regards,

 

Some cars have composite roofs, and have a championship, take the Blackpool racer, plastic fantastic TVRS.
