Looks like you're getting close to firing it up. Won't be long now.
 
When I initially bought the front AP calipers, they only offered one size with normal width pads (as fitted on the FP350S). More recently they've offered wider calipers to allow endurance width (25mm) pads. So I bit the bullet and upgraded to the wider calipers for the race car. Moved the regular width AP calipers to the 350R, so the two cars can share 18" wheels and rotor consumables all round, and pads at the rear:

I have the same (FP350S AP brake set up front and rear)
Are you able to still use the same rotors and caliper brackets with the wider caliper?

Do the rear caliper stay the same standard width pad and caliper?

Rotors and brackets are the same up front. I stuck with the same, narrower rear caliper/pad as rear wear is way lower.

The front caliper is CP9668-3S7L/2S7L -- special order as there is a minor machined relief added.

AP are also going to offer rears with an integrated e-brake, similar to OE. It will use larger rear rotors than the FP350S. Not clear whether they will package with 18" wheels, and availability sounded like it was 8 weeks out, so I've gone with the 350S rears for my 350R.
