With the C01Al-S chassis is the center screw hole on the AM08-1 simply not used anymore?

Correct!
The front end has been shortened by 1.1mm, and the rear end by 0.8mm.

I ran a Evo + c01al-s/am33-5/am49-3/c21-2 + at21s on saturday in 13.5 and 17.5 blinky tc. we club raced solaris medium tires, and then practiced w/ gravity rc carpet tires. after a bit of tuning, the car showed A LOT of promise. it was just as fast/stable as Larry's c01al/am30-1/c21 + at21s car.
