There are multiple versions of the ST-40 for multiple models; rotor diameter options of 328mm, 332mm and 355mm for WRX. Go to stoptech's website and print out the template for the caliper you are looking for and test fit in your wheels. That will be your best bet.

FWIW, the ST40 328mm looks like it might clear the 17x8 +45 RPF1 with a little bit of space, but the 332mm option was a bit sketchy. Good luck!
