RS Motorsport :: Classic Speed Restored

OK...It really is not my week. Trying to get the car ready for the cage but I keep finding reasons why I cannot finish those last few jobs.

MANY months ago I bought a Gartrac seat mounting kit. I cannot find the 8 square mounting plates that fit on the ends of the bars. Dont know whether I have misplaced them or if they never arrived (had a couple of other issues with that particular order ).

I will make up some plates. Anybody know what size I should make them?? The regs do not appear to give any specific requirements other than the competitor ensuring it is safe. I was thinking something like 50x50x3????

Why don't you ask Gartrac

I HAVE....but its saturday night in pommie land so I wont get an answer for a few days but I need to get cracking now!

OK...maybe I confused people with talk of Gartrac. When putting in seat bars of any brand, what size plates do you use?

I use 70mm x 50mm (2mm plate)

Or you could find the sizes specified in the CAMS manual

they are not in the cams manual. cage legs yes but I could not find seat bar regs...correct me if I am wrong

EDIT: I will correct myself. I just looked again and found it

structure by not fewer than four grade 8.8 bolts of minimum diameter 8mm. Where the seat is affixed to an
un-reinforced section of the floor pan, each attachment point shall be reinforced by the use of a plate of not
less than 75mm x 50mm x 3mm thick;
