[BeemerX1]

Hello,

I would like other people's opinion what rim to put under my black X1.
Picture here is my X1 with the stock 320 style 8Jx18" (ET30), this will be my winter set.

Don't know if I should go for the 405 M 8jx20" (ET36 so probably need spacers because they go 6mm inwards) from the F30 (3series) with 225/35/20 rubbers
on

or to go for

the 463 style 8,5Jx21" (ET25 is perfect, they go 2mm inwards and come 12mm more to the outside) from the F01 (7series) but with 245/25/21 rubbers (only 1,1mm smaller wheel diameter) instead of the normal 245/35/21 because the wheel will be to big otherwise.

Price difference is no problem. Should be nice under my car and 1 thing to consider is the weight of the rims on my 23d xdrive auto gearbox (260hp/470nm).

18" -> 12kg
20" -> 11kg
21" -> 17kg

My brains tells me to go for the 405M's (my car will be faster with those and it is better for my xdrive) and my heart tells me to go for the 463's (any idea if the xdrive and gearbox will survive this? would I lose a lot of acceleration?).

All input is welcome!
I can't mount any of this rims on my car just to look.
If anyone's bored and want to do some Photo-shop, be my guest.

After I got the rims mounted on the car I will see if I would go for a M suspension (no lowering, only stiffer) or a -30mm Bilstein/Eiback kit.

Kind regards,
Bart
