My understanding was that we were looking at the handling of our stock chassis'. For this reason, I fully understood your reasons to use similar tires, gears, engines, and a common driver to eliminate as many variables but the chassis.
This is what my comments to market pricing referred to:
Our gears are 3.10, it's economical.
Our wheels are bolt on, it's economical.
Our tires/wheels are 15", again, economical.
Sorry, I guess I could have worded it differently.
Hell, one guy is even whining about spelling

Boudy,
That’s why I said (In one post) 3.55 or 3.73 and folks who could not match this ratio should get as close as possible. If BMW has nothing close, run the normal ratio. (I doubt there would much difference in times, it just skews the comparison a bit.)
The JBL wheels are bolt on. I have nothing against a center-lock wheel with a nut, but you cannot torque a knock on and that worries me. (Also, a center lock wheel does not in any way increase performance.)
As I also said, if the chassis is properly designed, I bet that I would be within 2 seconds chassis to chassis at Willow.
15.16.17,18. I do not care. Just put Hoosier DOT's on them all.
The reason for the Hoosiers is to get tires that are equal in performance. (Street tires are all over the place and really would make a big difference.)
I know that folks are going to say the wheel and tire width really makes a big difference. But it is not quite as much as one might think from my experience.
Actually, if the suspension geometry is not up to snuff, they are going be much better off with a narrow wheel and tire. Narrow units are not as sensitive to camber curves (and God forbid, bump steer !) as a wide wheel and tire.
And I agree, this is meant to be fun and informative. It should not evolve into a pissing contest.
After all, everyone thinks the JBL will run away and hide. I do not. It should do well, but we are dealing with a package that has dynamic limitations and I bet the cars will be pretty darn close.
(If the basic designs are good, that is.)
