How does a spec miata run TTE?
#6
They used to have a blanket classification for Spec Miata cars but it looks like they replaced that with Appendix C—Pre-Approved Dyno Re-classing in the 2015 TT Rules.
Mazda Miata ’90-’93 (1.6L), no motor swap, non-BTM head, or F/I:
Your '90-‘93 Mazda Miata 1.6L with a maximum 127 rwhp on a Dynojet, and a Minimum Competition
Weight (w/driver) of 2295 lbs, will have a new PT/TT base class of PTE/TTE. Your new base tire size is
235mm. You will not assess modification points for Section B. Weight Reduction or Section C. Engine
Mods. However, all other modifications, including transmission and LSD, that are not standard items on
a base trim '90-‘93 Mazda Miata must be assessed points, with the following exception. Only +1 point
will be assessed, instead of +3 points under section 8.3.F.4 for the use of a 1997 Miata sub-frame brace,
IF the vehicle is also being assessed for size 205 tires, +3 for a Mazdaspeed front chin spoiler, +2 for
bump steer/shimming due to the use of Miata “R” model tire rod ends, and +2 for the use of Mazdaspeed
sway bars. You must be compliant with the above listed maximum Dynojet HP and Minimum
Competition Weight during any tech. inspection.
This option may only be used with a PTE/TTE or higher Final Competition Class.
Please keep a copy of this e-mail and the most recent Dynojet sheets and Dyno Certification Form with
the vehicle log book as proof of re-classing. Also, turn in a copy of this e-mail, the Dynojet sheets, and
the Dyno Certification Form with your PT/TT Car Classification Form to your Regional PT/TT Director.
Note that the car will still need to be compliant with the Minimum Adjusted Wt/Hp Ratio for whichever
Competition Class you choose to run in.
This is an Official, approved, Dyno Re-Class copied from the current TT Rules, Appendix C
Mazda Miata ’94-’97 (1.8L), no motor swap, non-BTM head, or F/I:

Those look like Spec Miata RWHP numbers and weights I think.
