I just ordered 4 rpf1 gold 17x8x45 Is this going to affect my handling or driving?

 

What are you going to use the car for? If your just daily driving it, you'll be fine.

 

wHAT about some small road track time or autoross rarely?

 

You might run stock AP2 sizes: 215/45-17 front, 245/40-17 rear.

 

what about 245/40/17s all the way around?

 

Have you visited the Wheel Fitment Guide stickie? Might wanna have a look: https://www.s2ki.com/forums/index.php?showtopic=342793

 

it depends on how you want the car to behave. are you planning on staggering the tires or not coz you only specify the wheel size? some people run on same spec all around since they have thicker sway bars in front.
