18s tend not to fit over the S brakes. not sure about the non-S. the "pattern of wheel bolt" is 5x120 5x130, if I understand what you're asking. tirerack.com shows you all of this when you're looking for wheels+tires, and will only show you wheels and tires that are guaranteed to fit your input car.

How well does the drivetrain hold up to slicks and drag launched?

Rear wheel drive base would only need the rear and they should easily fit the rear caliper

Mickey Thompson E/T streets 305/35 18 these would be the closest in diameter being 26.6 inches compared to a stock 20"Pirelli tire having a 27.4 inch diameter

Tyler’s is a Carrera T but with AP brakes.

From memory the lower suspension arms are the problem rather than brakes, cars with RAS find it hard to even run 19s I believe.

Default 19" wheel on 991.2 GTS?

On a 991.2 GTS, O.Z. 19" wheels may/will rub the wheel carriers...recommend whenever possible, test fit wheels. 19" wheels, out of the question on a 91.2 GTS.

18s will clear the rear brakes-but not the suspension arms (at least none that I have seen). I would go with a lightweight 19 inch rim and a MT ET street.
