Changing E30 M3 bolt pattern to 5x130mm

Can I change the bolt pattern of my E30 M3 to 5x130mm? How would I go about doing the conversion?

Why on earth would you do that?

And only with 20mm+ bolt pattern conversion spacers.

with those spacers, and stock fenders, you could run 17x5 wheels at most.

I have my reasons for wanting to do it and what is a bolt pattern conversion spacer?

You want to run P-Car wheels, no secret man...

To convert to 5x130 you have to mount spacers that offer the conversion.

Basicly a spacer about 20mm thick. It bolts to the stock 5x120 hub, heads of these lugs are recessed into the spacer so that they are flush. The spacer has a 5x130 bolt pattern drilled into it, with steel thread inserts from the back.

You then need to bolt a 5x130 wheel to the spacer.

In the end, as previously mentioned, you will be able to run about a 5-6in wide wheel with stock e30 M3 fenders.

Is there anyway to change the hub itself?

No one makes a 5x130 hub that is going to just swap in man.

i dont see why youd wanna run narrower wheels, especially on an m3, unless you plan to be doing some snow rallies or some shit. in which case im sure you could find something else to fit for less work....

I want to run 15x11's but they have a Porsche bolt pattern. I am going to widen the fenders but I need to figure out if this will work at all. Does anyone know how mcuh wider Azevedo Motorsports made their fenders? If I can only run 5" wide wheels with the bolt pattern conversion spacer then that means I would have to widen the fenders another 6" imches to have the rims fit, I think that might be too wide.

Dude.

You are not ever fitting those wheels on a e30 M3. Not with it looking even remotely not crappy.

Not flaming, just trying to be the realistic one here.

BBS basket weaves not cookie cutters.

The rims are nice, the tires are hard to get, and it would be a lot of work to fit those huge rims under those flares without a serious amount of work. What wheels did BMW use in DTM and does anyone know if BBS ever made a 16x10" or so with a 5x120 pattern, otherwise I'm gonna buy 16x8's

Fitting 18's on the car is fine but fitting 15x11's which is more represntative of an old DTM car is not. HUH think outsidde the box, the car was never meant for 17's or 18's yet I bet if you have aftermarket rims that's what you have.

No DTM e30 M3 ran 15x11.

Why don't you take a GOOD look at real DTM cars. They all have 17's, 18's etc
