Spec Miata Time Trial Classing, TT6?

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.

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.
