OK I'm in...Car #24...Tuesdays are prime for me. I could do it most other nights but being on the west coast I don't get off til 5:30 and have a 20 miles commute home. i don't know the # of laps you are thinking about per race, but perhaps we could start a tad later. 30 laps @ Sunset is only about 45mins, even 30 @ Sebring is a bit over 1 hr. The car list is pretty good, but there is certainly some disparity.
I would say @ A820 the 2006 Volkswagen Golf GTi would have a distinct avg over the 2005 Subaru Legacy B4 2.0 GT. We still have a couple weeks, maybe we should test some car combo's and see how even they are. I do like the WTCC idea better than supercars though, along with as Kabob said maybe a slight Hp increase to 325-350, that way you could add some Audi's, Subaru, Mitsubishi's, while excluding the 2 seat coupes, and convertibles.
