I've been looking to upgrade my stock 16" rims on my 2.3 Z3 up to the 17" m68 wheels from the e46, or to the 17" BBS RK's. There's a few things I've been considering though:

1.) weight - the m68's look like for all 4 wheels, they'll be about 16lbs heavier total compared to the BBS RK's (20-21lb wheels vs 16.8lb wheels). Or about 10% heavier including the tires. Right now my stock wheels weigh the same or maybe a pound less than the m68's. Would this difference in weight really be noticeable? Something you'd have to look for, or something that's really obvious?

2.) strength - being a daily driver, I'm worried about the potholes up north/etc that I'll be driving through, and I'm normally careful but I'd hate to have a lighter wheel get bent somehow just because I bought them for a very tiny increase in performance/handling.

3.) if I really wanted to (to try and run a non staggered tire width) I think I can run 235/45/17's on both the 7.5" wide front and 8.5" wide rear wheels right?

1.) Weight does make a significant difference. How much that difference is worth is for you to decide.

2.) Strength should not be a factor with either wheel. BBS makes some of the best wheels in the industry and they are known to be strong. OE BMW wheels always strong as well.

3.) If you would like to go non-staggered. I would advise a 235/40 on all four wheels with either set of wheels. 235/45r17 is a bit too tall of a sidewall. I currently have a set of 235/40 Hankook's on staggered M contours.
