Tend to agree with you, Chris. Especially for the tracks I run where we spend 80% of our time below 90 mph. Plus it is super easy to take the Aeromtions wing on/off.

I find it very interesting how Nasa decided to base class this car... The base model is a TTB*, the sport is a TTB**, and the Nismo is TTA*. I had special permission to make mine a non-sport and take a +3 pts for the SRM, given I had swapped the brakes etc. The old Nismo was TTB vs new one at TTA*, so basically it moved up by a full class plus a "*" (46 points). That's like saying that a 370 nismo will post the same time as 2008 Nismo with 315 Hoosier R6's, sway bars, and 20 points of power / weight mods... Seems ridiculous to me! Also, have a look at the base classes for all these "TTB*" cars...

Car Class Base Weight HP (mfgr) Weight / HP

Corvette C5 (inc. FRC w/o Z51) B* 3246 400 8.12
Mercedes SL55 AMG ('03-'06) B* 4280 510 8.39
Mercedes E55 AMG ('03-'06) B* 4087 469 8.71
BMW Z8 B* 3500 400 8.75
Ford Mustang Cobra R ('00) B* 3590 390 9.21
Porsche 996 C2 (3.6L)('02-'04) B* 2959 321 9.22
Mercedes SLK32 AMG ('02-'04) B* 3220 349 9.23
Lotus Exige ('06) B* 2015 218 9.24
Porsche 993 RS 3.8L B* 2800 300 9.33
Ford Mustang Cobra SVT ('02+) B* 3665 390 9.40
Audi RS 4 (4.2L) (AWD)('07) B* 3957 420 9.42
Porsche 997 Carrera ('05-'07) B* 3075 321 9.58
Nissan 370Z (non-sport) B* 3300 331 9.97

Ours has by far the worst weight / power ratio... And remember the 370z Sport is a TTB** and the nismo is a TTA*... TTB** includes the AWD Evo X MR and TTA* includes the current Lotus Exige S, Ferrari 355, 2004 Corvette Z06, and Porsche 996 Turbo. Basically, we get screwed in NASA TT! lol

It'll be interesting to see if I can make this car win in TTA. At some point, I'm going to move back up to TTS and hopefully that'll play to my favor - given it takes all this base class BS out of the equation.
