About Disc brake, spacer and rim

[kacyp]

Hello guy, i really need help here confuse already,first of all i would like to ask, originally fro e30 which side have disc break front or rear?mine got both, mean previous owner upgrade it already. my question is usually if people do this conversion, from which car did they take disc brake. and does it affect the offset of the rimi'm confuse becose, my came with a 17" japanese rim offset 40, and when i open it i can't find any spacer(or maybe i dunnoe which one is it). this is the reae tyre. for front i can see a silver plate between the rim and hub.one more then if i want to put on original rim back, does it will affect the offset since ori e30 offset is ? to 25 if i'm not mistaken, maybe later i can post the pic for you all to see.hope can help my confusion

E30 323i and 325i comes with rear brake disc and front ventilated brake disc. while the 318i and early 320i has non-ventilated front disc and rear drums.

Actually the original bottelcaps 14" rims has offset of 35. that's y the rims sits a bit deeper in the wheelarches. and most sport rims for E30 has more positive offset (~25) to widen the track width for better handling and looks better (as it fills the wheel well better).

As for ur 17" rims u got to compare with made-for-E30 17" rims for the offset. But I guess it shud be about 30+ for 17" becos of the width. Offset 25 is for rims 7" wide.

Thanks Fab,

So, these mean its true la for my rear wheel there is no spacer at all, so usually for rear rim off 40 also can fit right,coz rear wheels doest steer left or right(correct me if i,m wrong) the problem is actually came from the front wheel.

so know i can fit the ori bottle cap rim with no problem at all lah...thanks again
