2011 NAS SM Rule - JUST POSTED

Changes in the PDF are in RED
None of these changes would prohibit a SCCA configured vehicle from competing with NASA. NASA wanted to get the 99 cars closer to the actual weight of the 90-98 cars to make it perform the same under braking and corner exit.
Here are the major changes:
12.1: Restrictor plate and minimum weights (NASA e performed dyno tests to derive these numbers)
* 90-93: 2285lbs (no change)
* 94-97: 45mm (no change) @ 2340lbs (-35lbs)
* 99-00: 37mm (-4mm) @ 2390lbs (-60lbs)
* 01-05: 41mm (-2mm) @ 2390lbs (-60lbs)
13.2: NASA allowing both the 4.1 and the 99+ upgrade 4.3 but the 4.3 is mandated for the Nationals. It has not been determined yet if the 4.3 will be mandated for 2012.
14.1: NASA has mandated the 27mm front bar on the 94-97 for Nationals
15: Steering rack - NASA is allowing shimming between the rack & subframe.

any source for the 37mm plates? my motor is just being finished up and will need to get on the rollers soon - going to need that plate...
ahm

Plates will be available hopefully within 4 weeks (yes, bad timing). NASA decided the plate size this week, with the holidays to get ample supply made before announcing the rules was impossible. I will post like crazy when and where the moment I know they are available.

thanks - guess in the meantime we'll be doing some fabrication. do you know if they will be available from enterprises (ie the anodized kind)? or are they going to sold through a different outlet?
ahm

Yes please broadcast it loudly. this is throwing a wrench into my plans so to speak I have a new crate motor to put in and dyno I will have to wait for the plate now.

I wonder what the chances are that SCCA will adopt it. Are there rules firm for the year?
