Got home and spent time washing and waxing the wheel. I hope to finishing getting my X5D ready and mount them next weekend.

Nice! They look a hell of a lot cleaner now! Haha, be sure to post pics once they're mounted!

Are you getting these bored out for the X5d?

no i purchased 15mm H&R spacer from ECS that convert from 74.1mm to 72.6mm along with longer bolts from turner motorsports. I wanted to be able to resell them later on without hurting the fitment for x5m/x6m.

Sorry to be the bearer of bad news, but I'll save you some time.

The H&R reducers are made for the 5 series, and will not fit the X5.

Your only options are:

1. Bore the rear wheels out from 72.54mm to 74.1mm
2. Order a set of custom made adapters from https://www.motorsport-tech.com The downsides here are: 1. Minimum thickness is 19mm. 2. You'll need to source a set of lug nuts that will work on OEM wheels (BMW only uses lug bolts). 3. It's likely these custom spacers won't be as finely balanced as those from H&R which may result in less than ideal ride quality.

Good luck!

Have you tried using the adapters yourself? What is it about the adapters that prevent use on the x5?

This issue has been discussed at length in other areas of this forum, but in a nutshell the 5 series uses smaller diameter bolts than the X5.

Call Turner Motorsports and they will tell you the same thing.

So is the problem that the holes on the adapter are too small for the M14 wheel bolts. Then it shouldn't be an issue since I ordered the correct longer M14 bolts for use with the hub. Either way, if everything gets delivered today, I can test it out tonight.

I think you're missing my point. When installing any spacer you will need longer bolts, but the issue here is the 5 series uses M12 bolts, and the X5 uses M14 - which is a larger diameter. Your X5 lug bolts will simply not fit through the holes in the spacer.

so the solution could be as simple as using a drill press and drill 10 15mm holes into the 2 spacers if the bolts are too thick to fit through the hole in the spacer. I'd rather drill $130 spacers vs cutting the hub bore on a such expensive wheels.

I guess I just don't see a big problem here.

Definitely an option - my goal was just to make you aware of what you're getting into before you get your whole care torn apart, thinking you have all the parts for a plug and play install.

Good luck!

Thanks for the info. I'll report back on what I had to make them fit

[isugoo]

Great info. Thanks to jzbm3 for sharing the knowledge.
Please let us know how it goes!

Hey note46, did I mention all sales final?! Lol

I think your solution of boring out the spacers is definitely cost effective and will more than likely work. It's pretty much what I had to do to get my Hamann's to fit too. Good luck man and post pics!

Sounds good. I'm actually interested in how it turns out.

Awhile back there was another guy who didn't have any luck making them work, but it wasn't really clear if there were other issues in addition to the undersized bolt holes. Comparing the pics on the ECS site, it seems like the chamfer around the hub may be deeper on the X5 version...but I'm not sure if that will prevent your spacers from sitting flush against the hub.

If it were me, I'd test fit the spacers on the X5 to make sure they sit flush before having any drilling done.

Just catching up and thought I would chime in. I ordered a set of the spacers/adapters for the rear wheels from Motorsports Tech last week. My new winters (298M style) will arrive Wednesday so I hope to have some pics by next weekend.

15mm is the smallest Motorsports Tech said they can machine due to the hub lenght. But, spoke to the owner and he was very knowledgable about what I was going to do. Look forward to sharing the results.

EDIT: and he had the extended bolts in stock (in black). OE is 28mm and the spacer is 15mm so the bolt is M14x1.25 x 43mm long

ANOTHER EDIT!!: I just realized this is in the classified section. When I get the new wheels/tires and Motorsports Tech adaptors I'll start a thread with pics.

Not a problem. I'll make it fit! I have an assortment of hammer from small to extremely large!

Lol! Right on man, let me know if the spacers don't work out. There's a machine shop associated with the shop where I had my wheels mounted and they can custom make them.

I just wanted to post that the HR adapter worked fine here so anyone that finds this thread knows the end result.
