Paul,
Most of us are close to maximized points-wise in AM. The problem with the rules is that if you run 8" rims it's the same points as if you run 13" rims. Would you rather have 245 tires or 335? Same points.
Where this all went wrong was when HM was eliminated. In the past, people put 3.6L motors in early cars. This cost so many points along with other necessary AM mods, that they were limited to run 225 tires to stay in AM. This was the great equalizer. It kept 3.6L engines out of early cars because there wasn't enough points left to put big enough rubber on the cars. Anyone else remember when John Lusti showed up with an early car with a 3.6L and 225 tires? He got spanked by Dan because his car was almost undriveable with that much power and so little rubber.
Since HM is gone, the Carrera's and SC's now in AM, can put in "stock" 3.6 liter motors and put so much rubber to the ground that they are unbeatable.
As already referenced in this thread, Mark Kinninger who I'm sure we're all aware of his pedigree as a driver and Porsche mechanic (and builder of these new AM rat bastard mobiles

)came on this forum and stated quite clearly, and I quote:
"You guys should have seen the writing on the wall when Roland showed up with a 80 SC running a 3.6,short gears,coil-overs,big brakes and 315 tires in your AM class.Sell those early cars to the R-Grouppe guys and build (or buy) something competative.
Mark"
Seriously, what more does the rule committee need than the above sentences by the person who stated it?
Any of you ever been on track in your car taking near maximum class points and having a car in your same class lapping 5 seconds per lap faster than you?
The Rationale listed in the new Rules proposal talks about the frustration levels of early car drivers and lopsided rules. Who the hell else does this refer to other than the AM class drivers who have been complaining about this now entering our third year? Who else is complaining about new entries to their class being able to lap 5 seconds per lap faster?
And yeah John, you didn't submit any rules proposals yourself, but were you not assured that the situation in AM was one of the major issues that would be dealt with?
By the way, I don't blame Steve for this at all. The man has a full plate and he can't figure out every possible repercussion of a rule change.
