I must right up a full spec, i'll put it up later it may take some time

It's a road going class so as long as it would pass an MOT it pretty much fine.
There's a couple of things you need to do;

1. Tow Stickers front and rear pointing to towing points.
2. Earth cable from battery must be yellow (I just covered mine in yellow heat shrink) but yellow tape is also exceptable.
3. Ignition and Fuel cut off must be marked in direction of OFF (on a road going car that means the igniton key, I have a little sticker with an arrow showing which way is off)
4. Noise limit is 105dB (Which is crackers loud, haven't seen anyone fail)
5. Usual safety stuff is checked like seat belts work, seats are secure and bolted down safely, tyres are legal depth and in good condition, generally in good condition all round.

It's still quite scary as the scruitineer goes round your car they do give it a good look over.
