I’m looking at treating my f30 to some nice new Rotiform LAS-R, but I want to get the best fitment I can without using spacers because I want the wheel to be as concave as possible.

The company I’m getting them for is recommending,
Front- 19”x8.5 with an offset of 35
Rears- 19”x10 with an offset of 40

I’m looking to get the flushest fitment I can to my arches without causing damage or problems. Currently running stock suspension but will be going lower soon.

Any advise or pictures would be much appreciated.

Added some current pictures.

Sorry but the half-car pics you've provided are horrible. I see that you have a mineral grey f30 with black wheels that are not distinguishable.

Regarding fitment, the Rotiforms will fit without issue, however the rear lip will poke until you lower it. You may also desire a 5mm front spacer up front after lowering.

Regarding wheel choice, they're heavy. Heavier wheels and tires will affect acceleration, braking and handling to some degree, if you care

I'd get something at least rotary forged instead. However if you cant afford it or you're set on those wheels, it will fit.

Also I might add... the tires you gonna be using for this also will be a factor how much will it poke out on stock height and if they will rub after lowering.

FWIW, I ordered from BC Forged a six spoke design

FRONT - 19 x 9 et32, 235/40-19 tires
REAR - 19 x 10 et40, 265/35-19 tires

Here's the concave profile.
Mild up front (left), rear is medium (right).
This puts the wheels flush with the body.
( I have a .8" drop overall)



For reference, if you REALLY want concave, you have to go REALLY wide.
Here's an M4 with 19x9.5 and 19x11...
