Comments please: I'm seriously considering purchasing new wheels for my E89 35i: a set of brand new genuine BMW Performance 19" double-spoke 313 wheels in standard sizes to suit the E89 as follows:
Front: 8 x 19" ET29 offset
Rear: 9 x 19" ET40 offset

These 313s are to replace my V-spoke 296 wheels which are in superb condition having done only 11,000 km of normal driving dodging potholes on roads in Victoria (Australia) in need of maintenance. I read all about cracking 296s on the forum before my Z4 arrived down here and have been careful to avoid impacts.

I'm looking for feedback on the 313s, particularly any issues you have experienced.

@BLKZ I'm also in Melbourne and I am on my 3rd set of 296s! Did you change them over? If you've still got them and are looking to sell, I'm interested in buying.

The Z4 is a fantastic car but those 296s ruin the car experience when you get the 'your wheels are cracked'.
