Default J55 brakes

I have a 1993 with j55 brake option. Will soon be upgrading pads and rotors for HPDE.

Did the J55 option upgrade both front and rear, or just front?

I know the front is 13 inch. What size rear rotor will the j55 be?

Thanks

The J55 brakes use the same pads in the bigger calipers as standard 12" calipers.
