i dont know the benefits of upgrading the MC on a stock disc/drum setup. my stock MC was only 7/8 inch, not much of an upgrade to 15/16 inch, but i wanted to do everything. but i bleed the brakes today and it does feel a lil stiffer with the 15/16 MC. i got the swap from another member, cost me $300 for both trailing arms, e-brake cable, rotors, calipers, MC, no pads though.
