Is an e30 m3 brake booster/ master cylinder better than a e30 325i's? Thanks

some one has to correct me on this if i am wrong. but i think they are the same?

if not, i think the difference is negligible and probably swapping it wont make too big of a difference

Brake boosters are similar between te M3 and the non-M (except iX of course).
The M3 MC is 23.8m and has one 10mm and one 12mm outlets. Not the same as the regular e30 MC.

So would it be even worth it to swap? would thos outlets make a difference?

i have heard of people swapping for e34 or e28 boosters. maybe thats something to look into?

e28 has an hydraulic booster. It is smaller in size but a bit more complex in function.
e34 booster is standard.

Lee while you are here. How much are a set of front hats for a 332mm brake rotor for an e36 m3 going to run me. Just hats alone?
thanks

so there is no reason of swapping one in? the only reason im asking because a guy im buying a few parts off of has one for sale.

i would assume upgraded brakes. although it doesn't make that big of a difference. Maybe a little different petal feel, if you like that kind of thing. stopping power... marginal
