I have a set of genuine 21" BMW Star-Spoke 128 alloys fitted to my E70 X5 and I am wanting to bring them out a little more to fill the arches but I am not sure what size spacer I should go for front and rear.

I believe the offsets are as follows:

Front - 10 x 21 with ET 40
Rear - 11.5 x 21 with ET 38

Any advice on this would be greatly appreciated. Thanks chaps.

Well, I didn't get any response to this question so I decided to go for 15mm front and 25mm rear. I have also ordered a set of H&R springs - so they will all be fitted hopefully next week.

A bit late posting this then. I would kave put a straight edge against the tyre that was ling enough to reach the wheel arch and see how much room was left before the extremity of the bodywork

Interested to see before n after pics of the springs mate, was about to order some myself.  Lowering your X with H&R springs is popular in the states, some of their vehicles look great [emoji106]

Keep us informed!!

I'm interested in this too Hoops.. i recently bought some 20mm hubcentric spacers and longer wheel bolts for the rear of my 3.0sd. But when i came to fit them i found the outside diameter of the spacer itself was circa 8 mm smaller than the back of the std 20" m sport alloys!

I'm sure it would have been fine, but with a 2.5 tonne SUV i really didnt like the idea of not having a full contact patch of wheel to spacer and spacer to hub (plus it looked weird thru the spokes of the wheel!), so I sent them back.

Looking forward to your update

Hi just make sure that the spacers bolt to the hub then the wheels to the spacer as I have herd a lot of horror stories of broken bolts causing an accident ! Quite a few people have run rear wheels on the front so effectively having 4 rear wheels on the car but I wouldn't recommend it .
