Default How does a spec miata run TTE?

tires 7
coil stuff 5
sway bar 2
exhaust 3

6+point cage in most(unknown points)

Maybe a dyno reclass?

The cage is free (safety).

Also, you get some points back for 205/50R15 (the 0 point width is 235).

This is all for NASA 2015. The rules do change slightly every year.

You forgot all the points you get back for tire size. If base class E. And some are base class F with stars. Or can be on a dyno reclass.

On a 1.8 Dyno Reclass

Between the head work, AFR (Adjustable Fuel Pressure Regulator) and exhaust, not enough points left for the shocks, springs, sway bars, diff, front air dam and tires to stay in E.

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.

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

I don't think it's specifically from a spec miata. The 94-97 reclass is actually my email reclass that I had gotten before the rules came out, he must have thrown it in for Appendix C.

I don't understand how you can say you are a PTE driver and say an intake is unknown points.

A SM would get killed in PTE, is it even worth showing up to run TTE in one?

Doesn't matter if you win by an inch or default, winning is winning.

In the Texas region, the quickest race lap for SM is usually faster than the winning TTE laps, usually by a couple of seconds.

A small amount of the difference maybe drafting, but most of the difference is driver skill.
