I should also note that if you build a fully competitive TT5 car, which in addition to catless exhaust, tune, and coilovers, would also require weight reduction, aero, and maybe even E85, you're well into unlimited class in 86 cup. It's hard to have a car that is ultimately competitive in more than one racing sanctioning body. Focus on track time and improving your driver skill first, then once you have a solid skill set, pick your sanctioning body and build a car for that group. Hit up other events purely for experience and fun if budget allows for it.

Iím somewhat backwards from you. Iím more interested in the 86Cup as I have no chance of being competitive in TT5 due simply to a lack of skill. There are some really good drivers in mid-Atlantic region.

I donít mind buying a set of R7ís and some more wheels. Itís the second set of Hoosiers that I mind, and the third, etc. When tires start to cost more than travel and registration together, it hurts.

Without the bonus for 220TW I will be in Modified and Iíll get killed there, so I will have to run a harder tire for 86Cup to stay in Street. Iíll probably run the 265 SX2ís in 86Cup. If they fit the NASA template, which I doubt, Iíll try them in TT5. If not, Iíll have to think on it some more.

I actually just had the car in to the shop last week and came out at 189 hp peak (dynojet) and 2660 lbs (1/2 tank, no driver), so Iím not in terrible shape, but yes, I agree you canít really optimize for two different series.

Even in TTD trim last year my car was already in Unlimited running 225 Hoosiers.

This year bump 10whp (combo of fully uncorked exhaust and tune) and I am average 174whp, 185 corrected and 194whp on dynojet. Was at 2850 with driver last year. Need to be 2662lbs with driver (not going to happen).

Bottom line you cannot build for both series as both TTD (ex) and TT5 build will be Unlimited.

If ya'll don't mind me asking, what length springs are you guys running, and what ride heights?

I just picked up a set of used MCS coilovers and I need to get different springs rates. I'm limited to about 2.5" of bump (compression) travel in the front with the existing springs (200mm or 7.8" and no helpers) and I noticed that the collars are all the way at the bottom. I'm thinking that shorter springs would get me more bump travel and more height adjustability...correct?

For ride heights, it seems that about 1.5" lower than stock or around 25 1/2" ground to fender height is ideal...curious to hear what others are running if you don't mind sharing.

Pics for reference and attention:

I came here to lurk and day-dream. I'm not disappointed hah.

I think a FRS/BRZ could be THE car to have ST5/TT5 as development continues. What are you guys doing for aero, diy splitter and 9LR rear wing?
