Just wanted to throw some information out there, but all is based on part nr's gathered from the Z4 M40i.
Started with the brake rotor sizings and other BMW vehicles they are used on.
Combining that with the A90 tire sizings to get a possible match.

PCD: 5x112
Thread: M14x1.25mm
Center bore: 66.6mm

Front:
348x36 rotor
9x19 ET32

Rear:
345x24 rotor
10x19 ET40


Now i'm curious what people are planing to try and fit on the A90?

There's no way in hell they're moving to the audi 5x112 bolt pattern.

EDIT: Well, today I learned they are indeed moving to this bolt pattern.

Feel free to check all the new 2019 models from BMW. All use the 5x112 bolt pattern.

G15 8-series = 5x112
G20 3-series = 5x112
G29 Z4 = 5x112
G30 5-series = 5x112
G01 X3-series = 5x112
G02 X4-series = 5x112
G05 X5-series = 5x112
G07 X7-series = 5x112

I can confirm the wheel sizing for the supra as per the below I got from my dealer as Iā€™ve ordered a spare front and spare rear wheel.

5 x 112 is the PCD

Front 19x9ā€ +32 with 255/35 tire
Rear 19x10ā€ +40 with 275/35 tire

Old thread bump.

Anyone have an idea what the smallest diameter wheel we can fit to one of these is? 18ā€? 17ā€?

Iā€™m looking to get a second set of wheels for winter tires.

It depends on the inner barrel. I am pretty sure a 17 wouldnā€™t clear the brake caliper.

What about the weight?
I second that. If any member has the taken the weights of their stock wheels, kindly share them with us.

We need to know the base wheel weights. In order to help us decide on which lighter forged wheels to go with.
