Wheel Question - Forgestar F14's

Hi all, I'm hoping for some opinions and advice on a wheel set up. Currently I am on OEM 400M M sport wheels with a square set up. I have xdrive and want to move to a 19" wheel. I've seen some post with concerns that a staggered setup will damage the xdrive system but the 403m option is available from BMW with the staggered wheel/tire combo so I assume that's false. I would imagine keeping wheel and tire combo diameter as close to stock would be more important. I'm also stock ride height but possibly looking at H&R sport springs at some point.

Would the recommended set up be 19x8.5 Front and 19x9.5 rear? The company I am ordering through recommended 19x8.5 or 19x9 upfront on 245/35/19 then 19x10 in the rear on 275/30/19.

Unfortunately, the super deep concave's offset won't work with the F30 so deep concave is my only option. Should I go deep concave all the way around or semi concave upfront and deep concave in the rear?



This is a daily driver I am not trying to get too aggressive so comfort and reliability are not affected. I appreciate any feedback!

Thanks!

If you go with a 10" for the rear, I ABSOLUTELY recommend you go with a 9" front. A 245 will look a little wide on the 8.5" wheel, but will be perfect for the 9" width.

I wouldn't go 9/10 if I was on stock suspension since those offsets will be quite aggressive. You won't rub but the wheels might end up a tad outside the fender.
Unfortunately the wheels will be almost flat in a 8.5/9.5 setup.

8.5/9.5 by flat you mean less concave?

I'm running 19x8.5f et30 with 245/40/19 and 275/35/19r et42 on a x-drive lowered on H&R springs and so far no rubbing. This is on a F32 and don't know how different the F30 is.

What offset and tire sizes did you go with? Would you mind posting some pics on they're mounted?

I have DHP and in comfort mode the ride is just as comfortable as stock but the car feels a lot more planted and no noticeable body roll. In sport mode the suspension is way stiffer than with stock springs. I mainly keep the car in sport mode but only choose drivetrain under the options. When I feel like doing some spirited driving then I choose drivetrain and suspension. I was going to go with lower profile tires but now glad I didn't as the tire profile I have fills in the wheel well nicely and goes with the H&R drop. Here is a link to my thread with lots of pics. If you have any questions feel free to PM me. http://www.f30post.com/forums/showthread.php?t=959695

Honestly I forgot. I went into Forgestar since they're local to me and had them fitted. I'll send them an email to get the specs.

Tires are still a variable too. I've worked out a deal with the shop I'm working with to use whatever fits. We're gonna try to squeeze 285s on this baby!
