Choosing the bolt-on wheels on a coupe GTS 2wd... does it change anything in the suspension and brakes by selecting the bolt-on wheels over the centerlocks?

Or does it retain the Turbo S suspension, but just changes the hub?

Wheel choice does not affect which suspension comes on a GTS. There is an option in the configurator to replace the GTS suspension with the standard S suspension IIRC.

Yes, you still get the same suspension, e.g. rear helper springs, SPASM, 410mm front rotors

No, same brakes and w/o center lock wheels, a decent chance of getting tire service at a non-Porsche shop.
