STU Boxster/Cayman Question
On paper, the 987.2, 986.1, 986.2, 987.1, and 981 all seem like they would run within a couple tenths of each other (in that order). That's assuming they can all fit the same wheel and tire setup, they all respond about the same to ST* modifications, and they all have decent enough gear ratios. But I'd like to double check those assumptions. Also, the Cayman seems like it would be about 0.1 faster than the Boxster in each generation, but at a pretty significant price premium.
Questions:
- I saw somewhere that the 987.2 can fit a 9.5" front wheel and 11" rear wheel. Is that true for both Boxster and Cayman? And 987.1 also? And 986? And 981? I don't mind searching for the info, but maybe someone already knows the answer
- At least one of these has a really tall second gear, but I'm not sure which generation. Maybe the 981?
- Anything else that would give one of these generations a leg up on the others? Gearing issues? Differential? PDK? If you were starting from scratch, is 987.2 the obvious choice?
- 981 (non-S) seems like it would be the slowest of the bunch. Anybody think this would be a better choice? Maybe it can fit more tire?
- Does anyone have an STU-prepped car they might sell in the spring?
- Does anyone want to buy my 997.2 C4S PDK?

981 SST is a bunch of fun without a ton of parts, but I’m afraid the SEB is about to ruin that, and zero chance of keeping up with grant reeves in a z06

I don't know too many specifics outside of the 981 but the newer cars generally have better/easier wheel/tire fitment as the cars are designed around bigger wheels. That said you can probably fit just about anything on any car, it'll just require sacrifices elsewhere, especially ride height.
Along similar lines, the newer cars generally have more power but longer gears. But maybe there's some outlier, you'd have to do some research to figure that out. The 981 and 987.2 have the pdk, which is probably what you want if you're looking for outright speed. Without doing much investigation I would think the 987.2s would be the best choice, with the base 981 a close second. That's assuming they all stay in the same class next year.

@Auto_Werks 3.6 If I head down the SST path, I think it would have to be in an Elise... but really I would rather not have to compete against anymore Z06s
