Quickest/fastest quarter mile on 15 inch "cosmetic" all season tires like BFG T/As (etc)?

They re-produce these tires, so I'm sure they are rated better, & if you've seen these cars, they are like show car condition, so I doubt they would risk running the tires if they thought they couldn't handle the speed. Just my opinion.

I hear you but unless the manufacturer says so, you can't count on them being better than the originals. Besides the "S" speed rating is for the current releases of these tires.

F.A.S.T. means "factory appearing, stock tires", which translates to "looks stock, and runs stock sized tires", but is anything but stock. Still impressive to see what some of these cars can run, but they are far from "showroom stock".

Yeah but the rules are pretty straight forward when it comes to tires:

14.01 Wheels must be correct*, including correct* diameter, width and material.
Note: Width may be upgraded to a maximum of 6”, if the correct* wheel is narrower than that. Reproduction wheels OK.
14.02 All 4 wheels and tires must be same size.
Exception: Mopar TA Challenger came from factory with G-60’s on rear and F-60’s on front.
14.03 Original equipment reproduction bias-ply tires only. No soft compound tires of any kind are allowed.
Retread tires are not allowed. Any car is allowed to upgrade to a maximum size tire of G-70 of the correct* wheel diameter.
All cars that were originally available with a 60 series tire can upgrade to a maximum size of G-60 tire of the correct* wheel diameter. ...
