sn8byte Posted December 23, 2010 Share Posted December 23, 2010 http://http://www.nasaproracing.com/rules/spec_miata_rules.pdf 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.

Members Trevor M. Posted December 31, 2010 Members Share Posted December 31, 2010 a couple of questions... 1) Is there a specific distributor that we need to purchase the new restrictor plates from? 2) Will there be any changes to the racing format in 2011? (I heard that we might go from 2 races on Saturday and 1 race on Sunday TO a 1 race on Saturday and 1 race on Sunday) - When will the MSRH race schedule be posted? Thanks, Trevor SM90 Quote Link to comment Share on other sites More sharing options...
bucketlist Posted December 31, 2010 Share Posted December 31, 2010 Trevor, I think most of you #2 questions are specific to the Texas Region. Hopefully Myron will lobby for 3 or 4 races per weekend like the AI/CMC folks get. Quote Link to comment Share on other sites More sharing options...
bpanther Posted January 3, 2011 Share Posted January 3, 2011 2) Will there be any changes to the racing format in 2011? (I heard that we might go from 2 races on Saturday and 1 race on Sunday TO a 1 race on Saturday and 1 race on Sunday) - When will the MSRH race schedule be posted? Not sure who told you one each day, but probably not likely unless that is what is lobbied for. It will change from weekend to weekend, but you could have anywhere from 2 races per weekend to 5 and ranging in length from a 15 minute qualifying sprint to a 40 minute stretch. Weekend schedule usually goes out a week before the event. Plan on 2 each day for MSRH. Quote Link to comment Share on other sites More sharing options...
dunk Posted January 19, 2011 Share Posted January 19, 2011 Any word on when the new smaller 99 plates will be available. Mid-A first race is approaching and we're running out of time to schedule dyno time and do the chassis setup. Duncan Quote Link to comment Share on other sites More sharing options...
fiveo Posted June 27, 2011 Share Posted June 27, 2011 I may be behind the 8 ball here but can anyone tell me if SM is allowed to run an alternative tire now that we have this Toyo shortage? I know AI and HC are running exclusively on Hoosiers because of said shortage. Thanks. Quote Link to comment Share on other sites More sharing options...
kbrew8991 Posted June 27, 2011 Share Posted June 27, 2011 NASA still requires Toyos for SM. That particular size hasn't been hit like the other classes tire size(s) which lead to them being opened up. Quote Link to comment Share on other sites More sharing options...
fiveo Posted June 27, 2011 Share Posted June 27, 2011 Cool thanks Ken. Are you going to be runnings Nats? Quote Link to comment Share on other sites More sharing options...
kbrew8991 Posted June 27, 2011 Share Posted June 27, 2011 not this year, budget just isn't there. 2012 with bells on and a cooler full of WhoopAss though Quote Link to comment Share on other sites More sharing options...
CWeber Posted June 28, 2011 Share Posted June 28, 2011 word is all Toyo RA1s are being shipped again now anyway so the temporary shortage should be over regardless... Quote Link to comment Share on other sites More sharing options...
bpanther Posted July 6, 2011 Share Posted July 6, 2011 Correct. There are several thousand RA1s in the 205 size available. Quote Link to comment Share on other sites More sharing options...
