In Reply to: Advice on wheel spacers needed! posted by NR on February 07, 2000 at 15:11:57:
: I have a set of E36 17" Contours wheels that I would like to use on my 92 535i. I know the E34 requires a +20mm offset. I believe these wheels have a +42mm offset. I tried mounting one of the wheels in the front to see how close it comes to hitting the strut and they hit upon tightening the bolt. Another note is that the hub size is the same which means an adapter won't be required.
: I'm thinking about using a 20mm spacer. Is this the correct size I should use? It will probably require longer bolts, what size do I need for the ??mm spacer application?
: If I get any spacers I want to use a hub-centric spacer. I know H&R makes them but are there any other manufacturers (websites, pricing)?
: All input on this topic would be appreciated!!
I'm just visiting this site as I don't have an M3. I currently have a 6.2 mm spacer for my front wheels and I wouldn't run 20 mm spacers. It probably won't work anyway. With a spacer that thick, even with perfectly matching hub, the hub won't be seated deep enough into the wheel thus the weight of the car won't be sitting on the hub, rather it'll be supported by the bolts. The only thing the bolt should do is keep the wheels pressed against the hub, and the hub should hold up the weight of the car.
If you do find that the hub is not a problem, make sure the bolts are hardened and are long enough so that it thread deep (about the bolt's diameter).
Please take my suggestions with a grain of salt, as I could be wrong in some aspects.
