Appropriate Wheel Offset for 18" Wheels?

Digging up this old thread. Really appreciate the guys stepping outside the norm and fitting up bigger wheels for grip performance.
I just picked up a set of aftermarket wheels front 18x10, +40 offset, and rear 18x11 +52 offset. Came off a newer Boss 302 mustang. I'll be tossing these on my resto mod 69 GTS 383 car.

What are you running for brakes in the front? And how about rear axle and brakes in the back? Spring relocation and mini-tub in the back?
