320i booster + 25mm MC

[isra]

hi guys i just finished my m52 obd1 swap and im really happy with it.

i have a question about the brake system im running a 320i booster with a 25mm MC. the brake pedal is very hard, is that normal?

before swap i was running a stock 325es booster with a 22mm MC

i was thinking that maybe the 320i booster was bad but the car brakes good, but i dont know so any help out there ?

From what i have read the pedal gets harder when using this set up, I could be wrong though?

P=F/A Pedal effort will go down some with your old smaller diameter master cylinder or a stacked ix type booster.
