WRC RB4 would be great, I think we need a couple of RB4's but isn't their supposed to be a rally pack coming out for LFS? Is so then no need for this.
Trucks definetely and karts would also be great fun.
Also the LEGENDS cars would be good fun, small light and little engines which rev like fewk!
For those of you talking about the F1 car racing another 2 differnt cars round the track, It was one of Jeremy Clarksons videos (Apocolypse Clarkson I think) Jaques Villeneuve (sp?) in the BAR F1 car, Colin Mcrae in his '99 (I think) Ford Focus WRC and Jeremy Clarkson in the Ford Cougar. Jaques was "stuck" on a crossword, he could't get a 3 letter word which has 4 leg and barks, what th hell could it be!
Sorry for this total pointless info, that would be a fun race if oganised properly, a handi cap race round KY or something.
Maybe RallyX form racing, like the faster 4wd turbo cars going 1st and 10 seconds later the slower 2.0 FWD cars. Would make good racing.
Hope at least some of the ideas in this thread get put into S2 or S3 like the trucks or V8 supercars/brutes.
