I think Rahal/BMW Racing doesnt have what it takes to beat the likes of Flying Lizard or Corvette Racing. I predict the M3 is going to be running in the back of the pack like the Robertson Racing aston's last year.

I will agree. Porsche will run away with the GT2 title. But it's about seeing BMW back in the mix.

Rahal has the skills as a team to develop a winning car.. BMW has always been good at playing the rules to be competitive... Corvette hasn't had to really race anyone in years.. which means they didnt push themselves hard enough lately... because they didnt have too.... if you watched the show tonight.. you would heard one of their main guys say it will be harder for them.. to race gt2..... ALMS is an American based series.. so the vette will always have support everywhere you look.... we will see after June... ps.. to compare Rahal to Robertson is laughable.. |

"Chassis/body: Unitary construction steel body..." It isn't specific, but I think they do indeed start with a 3 series body-in-white just like a factory M3 does. But they no doubt make tons of modifications to it before they start bolting and welding the rest of the parts on. I agree it would be cool to have a list of all parts, if indeed more are shared with the production car. Unfortunately I don't think we'll ever see such a list. Anything shared beyond the body and block is sure to very minor though. Quote:

I wonder if the "axles" must too come from the factory car? The info above states "based on production" but that could be just referring to the basic design and not necessarily actual parts. |

Actually, Corvette is racing a limited GT1 schedule for 2009 and will switch to GT2 in 2010. GT1 is being eliminated after this year.
