Help Me Decide on 2nd Set of Wheels!

thanks for the X5M specs, this very helpful.

So your avant garde offset are actually more aggressive (smaller number means sticking more outward) than the X5M. I assume this is because your rear is only 10" wide instead of the 11" of the X5M.

I'd love to see picture from other members sharing their wheel offset. This is really the tricky part with any car. Stock is always too ugly conservative, but too little of an offset and the wheel stick out too much and you get all road debris spitting on your side body panels...

I wonder if tirerack can work on the bore of the OZ wheels I'll check it out.

If you mind me asking how much did you pay for the wheels and/or how much did you pay for the bore adjustment work ?

I agree, a smaller number, or reducing the offset pushes the wheel outward.

To figure out exactly where the Avant Garde Wheels sit compared to an X5M:

Rears
X5M wheels Rear - 20" X 11" wide - ET 35
Avant Garde Rear - 20" x 10" wide - ET 20

Two things are happening:
1) wheels are 1" less wide so this would pull the wheel inwards by 1/2 of this distance, or 1/2" or 12.7 MM inwards

2) The offset is 15 MM less so this moves the wheel outwards

Combining #1 and #2 we have 12.7 inwards and 15 mm outwards so net movement outwards = 2.3MM or .09 inches.

Fronts
X5M front wheels - 20" X 10" wide - ET 40
Avant Garde front - 20" x 10" wide - ET 38

So the reduction of offset is 2 mm, which moves the front wheel outwards by 2 MM or .08 inches

Conclusion: The Avant Garde M510 wheels are a little less than one tenth of an inch further outwards compared to a stock X5M
