Not unless you have a CR 
I dont have a dyno plot for my car but lets say 212 average? so 245 or smaller (+0.7), A7's (-1.0), Less than 3000lbs (-0.1). I am looking at 2628 min weight. With R7's: 2416 lbs.
I can see my car getting to 2700 or really high 2600s like some of the other caged cars but that's about it. With what I plan to do in the near future i figure i will be 2720 (avg hp of 219 on A's). How much is being down 7hp average going to hurt lap times? Maybe it wont be much. The fast S2k in TT4 are going to be the guys with light cars like Wynn and Dysen or my pig with engine work.

And that part of the rule is dumb. I have a 2006+ dbw no title race car with More different VIN numbers on it then I can count on fingers and toes. I could claim it's a CR if I found some VIN's on it that are CR Vin's and no one could tell either way. Need to allow full conversions. Since everything on a CR can be changed legally in TT4 any AP2 should be allowed CR aero cause who's to say it's not a cr... or is.

Clarification: I ran this up to someone in the know and since the CR is a different line item its okay to keep my CR aero

Thats BS, dont penalized a special edition car from converting to a base model for years and then tell the owners they now have to make it a base model.
