I am starting to get more serious about tracking the car and feel that the FR-S will be with me for a few years and eventually make it to a semi/full track-prepped car to compete in time trials and potentially wheel-to-wheel (if I decide to go with all of the supporting safety equipment). That being said, I am also wanting to start with a few modifications on the car, but I don't want to go so crazy that I place myself in a higher class then TTD (in NASA, or equivalent in other series) and have to compete with cars that were initially classed higher. I have read through the TT rules and classification and I feel that I have a decent understanding, but some of the wording is weird. Furthermore, I am only allowed 19 modification points before I am bumped up a class.
Therefore, my question is, what mods are the most worthwhile in terms of performance gains (brakes, suspension, engine, etc) that will allow me to compromise the best and keep in the class I want? I could easily go with full slicks but that would take up half my points and I am not sure the car would perform well with slicks and few to no supporting modifications to other components. I have included the link to the classification sheet if people aren't familiar. One specific question relates to the use of coilovers, as it seems that you are double-charged points for the modification of the shock and springs...?

We are campaigning our Project BRZ in TTD and hopefully move it up to PTD eventually as well.
So like you we've been pouring over the rules and points.
Something you may not be aware of is that slicks don't cost as many points as you may think. Since 245 is the "base width" for the TTD class, if you run the Bimmerworld Take-off Continental tires that we are running in 225-45-17, you gain back 4 of the 10 points that the tires cost you. The tires run $250/set shipped as well.
Here is what we have done so far on our car for TTD...
Continental Take Offs in 225-45-17
MachV Awesome Wheels
Crawford AOS
Touge Factory Brake Ducts (Got them used cheap, but found out they actually work very well after the fact)
Motul Fluids (Oil, Trans, Diffy, Brake)
Hawk HP+ Pads (going to move up to the Street Race Pads shortly)
Eibach Prokit Springs
Great alignment
P3 Cars Vent Gauge to monitor vitals
Our plans going forward include:
Tune & Header back
Coilovers
Huge Oil Cooler
We feel that it will have us fairly competitive in the TTD class. We also are working with several other teams and NASA to push for a Spec BRZ/FRS class in the next few years based on the TTD/PTD standard to make the series even that much better.
