Thanks guys, much appreciated.
My 23D is stock with the 17" 7.5 wheels, and I'm looking at some 19" X3 wheels (see link here
http://www.ebay.com.au/itm/281519806...84.m1423.l2649) which are 8.5F and 9R.
My issue is just whether the offset on the front will be too different. Current setup is an offset of 34, but the new wheels have an offset of 46 on the front, which means about 25mm less clearance on the inside of the wheel.
Do you think that's a problem?
GTony, FYI mine's an 2011.5, with 35,000kms on the clock, has business nav and a few other bits and bobs, I got it for $37k. I didn't think that was a bad deal, has an extra year warranty and scheduled servicing so a pretty safe bet. Surprisingly the twin turbo has almost as much pull as the old N52 6 in the 130i... although doesn't sound half as good!
