Looks like it's out for member feedback as of March FasTrack...write your letter:
• The following listing change proposal has been provided by the STAC and is being published for member feedback: Add the BMW E46 M3 to class STU. (ref. 07-001)
Thanks for the notice, Brian. It seems they can move pretty quickly on this sort of thing. I went ahead and began STU preparation (SMS for now) - just got coilovers instead of the R comps I was planning. I'll get my letter sent off soon. (Do you happen to know where it goes to? SEB address?) I don't know what more I can say beyond I agree with it and don't think the M3 would dominate in the class given the success of the STi and Evos at national level, but I will try to come up with something. So, if they got this rolling so quickly, I wonder if they might get something official in the next few months?
There were some other interesting ST proposals. Widen tires in STX for RWD and FWD to 265mm and remove the STX 'single' turbo limitation. (I wonder if this would open STX up for BMW 335i and 135i)?
