I'm trying to buy some Work rims for my car but I don't know what size disk I need or have. Does anyone know what size disk I have or need? I own a 2008 335i Sedan...e.


Thanks!

I guess it's the distance the rim sits away from the rotor or something, I'm not very versed in this area. Little or no knowledge at all.

thats called "offset"... you'll see it marked/stamped/sticker on the wheels with it saying "ET 30" or some other number.

It's not the off-set, I know what off-set I need...there are couple of things that you need to consider when making a rim purchase..I could be wrong but there are usually 3 different types of "disc" size or whatever


Rim width
Rim size
Off-set
Disk(c) size (I'm stuck on this one)

hmm.. the only other measurements I can think of that you haven't listed is the bolt pattern for the hub (like 5 x 120mm), or the size of the center bore.

never heard of disk size, unless you are talking about brakes

Forgot to throw in the PCD thanks!
Look at the ad on this thread there is A disc and L disc, that's what I'm talking about. I mean do we have large calipers or regular ones? How much bigger are they then like brembo? High pad, mid pad?? lol.

? Anyone

Suppose to use an "A" disk for the front
for Big Brake clearance, and "O" disk in
the rear. O disk has a smaller and thinner
back pad so u can have a bigger rear
lip. Some folks run "O" disk in the
front (u can only do this if u do NOT
have, and will not run a BBK) so that
they can also run a bigger lip in their
front wheels.

make sense??

Thanks for the info...I'm actually not using a BBK nor will I in the future, really have no need. I am using the "O" disk in my front 19x10 +20, and will be using the "A" disk in back with 19x11 +20...That's my plan, and I'm sticking to it.

Seriously tho, thanks alot for info. No one really had any good info on this, anywhere.

^^ A disk will give u a smaller lip
due to a bigger back pad...

So, are u sure u want a small lip
in the rear tho??
