Cams, Speed Events & Sunroofs

[hrd-hr30]

my new Sileighty has a glass pop-up sunroof. I was planning on replacing the glass with lexan in the interests of weight & safety. OK mainly weight... But I have a niggling doubt about CAMS disliking sunroofs at speed events. I seem to recall someone at a local hillclimb being given a hard time about a sunroof years ago but maybe I'm imagining things. I can't see any reasonable grounds to disallow them its just a gut feeling I have. I mean you can run an open car at speed events. And if you roll a sedan you're going to break glass somewhere anyway and my sunroof will very soon be lexan anyway. I've read and re-read the General requirements for Automobiles and didn't find anything... Does anyone have any experience with this?

Harry I know of a series 3 rx-7 that was given a hard time years ago too, but currently I think you're allowed to run with a sunroof. But, and this is a big but, there's something in my mind telling me that in order to run it needs to be a metal one?

Pop rivet an alloy sheet on?

cams specify a metal sheet cover the opening on a sports sedan, but not sure if this is the same for your car or the speed events....

yeah the specific rules for sports sedans are the only one I am aware of (ie must be replaced with same material as rest of roof). you might have to take a copy of the manual to convince the scruitineers though.....

thanks guys. At least it only affects CAMS events. Thankfully there's lots of AASA events up here anyway, but there are a few CAMS supersprints I want to do as well. Some of which will probably be in Sport Sedan class, or maybe in Sports Cars - I know the 180 didn't make it into IPRA thanks to the Touring Car interior dimensions requirement. I might go with the sheet alloy cover as Ben suggested. Another thing to add to the list!
