Hi Gerry,
Good to hear from you again - hope to see you at the tracks this year!
The rules are basically the same as the regional associations, the summary is only a rough outline - for the detailed technical regs, click on the
link. Both the standard class (J-276) and the roadgoing class (J-ROAD) require list 1A tyres (tech reg 3.6).
The rules for J-ROAD are essentially identical to the regional associations class B4 (which was A3 last year...). This is to allow people to tie in with regional association championships (and lots of other events) if they wish.
The J-MAX class is free and can run competition only slicks. Please note Toyo Proxes R888s are not list 1A tyres (these are list 1B, and not eligible for J-276 or J-ROAD)
Spencer.
