The sup regs arn't out yet, but M1-M3 will now be S1-S3 (apparently there are going to be changes to entice HSV, FPV, Audi and others in), and modern will be split into 2 comps Early and Late. Late is on a rolling 6? year plan (i'll check the proper gap tonight) so 09 Targa will be 03-09- Late Modern, and catigory 8 will extend to 90-02. And 10 Targa will be 04-10, and so and and so forth.
And the max octain fuel will be 98 ron. This will probably piss a few people off, but i don't think it will change the pecking order, as all the top runners are on similar fuel as it is (ELF, VP.....)
I'll copy and past the e-news up when i get home.
