I'm looking for a track set up for my '16 RCF. Tire options are very limited in 19" so I'm thinking of going 18". Does anyone have specs on 18" wheels that clear the brake calipers? I'm looking for width and offset for front and rear. Anyone done this yet?

I have read 19 inches is the smallest size we can fit on our RCFs. 18s does not clear the callipers. I think there are some rare 18 inch wheels that do fit. In 19s, you can get Cup 2, R888, Pirelli Corsas etc. as track dedicated tires so i am not sure why you think the options are limited?

18" wheels will fit in back but not in front.

I'm pretty sure i've seen people putting 18in on RCF. It really comes doesnt to spoke design for Brembo clearance.

The spokes enter into the equation of course, but the caliper/rotor assembly is close to an inch larger than on the ISF. So it's an issue with the wheel rim. See this thread for an idea of just how large the RCF/GSF calipers are:
