mcolangelo2005 Posted January 25, 2020 Share Posted January 25, 2020 I'd like to participate in NASA Time Trials with my 1997 Spec Miata. Using the NASA TT car classification calculator and browsing the rules, it appears that my car (probably a very typical Spec Miata) falls into the TT6 class. For those of you who have TT'd their SMs with NASA, is the class you ran in? I'm really asking for a sanity check. My car is compliant with the NASA Spec Miata rules and includes: weight: 2400lbs HP: 124 whp Weight/Power=19.35 OEM hardtop front spoiler adjustable end links Toyo RR tires Torsen LSD roll cage Thank you in advance for any feedback.

That should be good. Do not forget to take -0.7 for the upper A-Arms. 1 Quote Link to comment Share on other sites More sharing options...

Front spoiler is not allowed in TT6. A few other things legal in SM require mod factors in ST/TT like extended ball joints and drop floor. Edited January 29, 2020 by Mike W.
