Jer,
This is the setup I've got on my A&C
I have 11" rotors all around with Outlaw 4 piston calipers in the front and Explorer in the rear. Originally had the big GM in the front which Joe supplied.
Rims are PS Engineering. Front are 15 x 7.5 or 8 with a 4.5 offset. The rears are 15 x 9.5 or 10 with a 4" offset.
Tires are BF Goodrich. Front 245/60 Rear 295/50
