What did you do to / for your F15 today?

[srmmmm]

Rear damage repair scheduled in January. I was promised an SUV loaner then (after holiday shortages) from the rental agency. I've had too many needs for the roof rack and interior space to be stuck in a sedan for two weeks.

Ditto TriX5. I used my old e53’s Style 87 wheels as a winter set-up for my f15 X5. The e53 has a 72.56mm hub and the f15 has a 74.1mm hub.

I used either 12mm or 15mm hubcentric spacers that went from 74.1mm to 72.56mm…along with extended wheel bolts (added the width of the spacer to the existing lug bolt length).

So no need to waste all the money you spent…you can still use them with spending a few more dollars for spacers and extended bolts.

Here’s some images with the Style 87 wheels mounted on my f15:

That is such a fantastic tip. Can I a mount e53 on e70 using this trick?

Yes, you can mount e53 wheels to an e70 or f15 X5 if you incorporate hubcentric spacers that bridge the 74.1mm hub of the latter X5s to the smaller 72.56mm e53 X5 hub.

Do take into consideration the wheel’s offset because most don’t want the wheels to stick out past the fender. For those unfamiliar…to get the final wheel offset when using spacers…you DEDUCT the width of the spacer from the wheel’s offset. So a 45mm offset wheel with a 15mm spacer installed will have a new offset of 30mm…not 60mm.

I dug back thru my online purchases and found that I did purchase 15mm spacers. The vendor doesn’t have any online presently…but a quick eBay search did find some…the pic below is for 20mm spacers & extended bolts being sold for the e39…but these would also work for the e70/f15 since they have the same wheel bolt pattern. But you’d need to contact the vendor about the lug bolts…the X5 uses a slightly different lug bolt.

N55 Turbo 3.0


Got 22.1 on the southbound trip and 27.9 on the northbound return.

It's only turning about 1900 rpm at 80 mph.

Wow on the 3.0 newer model. The e70 30 gets worse mpg than wife's 50i!

I need to replace my 01 e53 (killed by deer) but budget will keep my grounded to another e53.

I saw an 08 that is possible so I may squeak into an e70 but n52 I think which prob will be very similar mpg to my EX five (I made that up the other day).

I stayed away from the E70 because of the broken differentials, and the ones I had as loaners always felt overweight to me. The F15 seemed to retain a higher degree of nimbleness. Transmissions seemed okay on them though.

Do you have air suspension? I'm trying to figure out what is the difference between mine and wife's e70 regarding handling and road feel. Mine feels much closer to the e53 and I haven't figured out if it's a sports suspension thing, bigger wheels thing or air suspension thing.

I do not have air suspension and am running the 255/50R19 tires. As I recall, BMW used more aluminum components on the F15 to cut some weight off the E70 design.
