Hi, recently upgraded rear brake rotors from 294mm to 314mm, with stock 1992 caliper bracket is too small if I purchase 95+ model caliper bracket F124-26-281 will it still fit 1992 caliper?

 

Yes, I think, but it's not really an upgrade if you don't increase the size of the front rotors. You're going to throw the brake balance off.
Maybe do your research before your next "upgrade?"

If you decide to upgrade to the 17" fronts, just be aware that the calipers are not the same, since the rotor's aren't just bigger, they're thicker.

 

Yea the caliper fits with new bracket and fits larger diameter rotor.
