As of right now, these are considered a test fit. Curva is developing a wheel that will be in the proper specs.

19x8.5 +35 (+15mm spacer / +20)
19x9.5 +35 (+5mm spacer / +30)

I feel like with these specific wheels and their profiles, another 5mm on the front and rear would have been good.

If you go with those profile sidewalls you're increasing overall diameter of all four wheels by 5-6% which seems a lot, and will have the effect of gearing up the car (if I'm not mistaken), which I suppose would put more pressure on the drivetrain long-term.

If I were you, I'd revise the tire sidewalls to 35 front and 30 rear. Still allows a good amount of sidewall on the tires and keeps the difference front-to-back within the scope for X-Drive. Offsets should work well as you have them, I plan to do something similar soon with the following specs (I have X-Drive and Adaptive Suspension which is a little bulkier on the strut):
Front: 20x8.5 et 15 - 245/35/20
Rear: 20x10 et 37 - 285/30/20

I should note, I'm relatively new to all this myself, but have done a lot of research at this point.

Wow. I'm loving the aggressive diffuser and front bumper! Not sure if you even need a lip on the front any more! How's the fitment of both the diffuser and front bumper?

Powder coating aluminum above 300 degrees F will revert the temper in the material, making it soft. It’s a temperature and time function where 300F is not going to change it much but a couple hours at 450F will make a permanent reduction in strength.

Took a few wheel spec as reference and took a gamble on these FlowOne wheels on sale on TireRack, I think it turned out pretty good.

Tires are some clerance 265/35-18 RE71R TireRack found in storage. Wheels and tire are both square setup.
Car has since been dropped on Dinan Springs, no rubs or issues so far.

The front ended up needed a 5MM spacer cause it wouldn't clear the strut.

No problem, you actually did it in the other thread.

So much more option in 18inch. I may look into swapping to M3 brakes if I find a cheap kit to be able to go down to 18inch

I am restrained to 19inch with the track package unless Apex releases some high clearence 18inch wheels wich could be very possible.

dezau Do you think 265/40-18 would fit well ?

For the front, mayyybe. Might be a little tall.
For the rears, I'm 90% sure it wouldn't be a problem. It'd help with 2nd gear top speed a little cuz it tops out at 51.

Have to agree the ratio difference between 2nd and 3rd gear can be a bit annoying in some situations..

Brand new to the forum and brand new to the BMW family. I have a 2019 330i sDrive. I want to switch to a 20" bronze wheel/tire combo. looking to keep the stock feel and drive, will also add a slightly lowered stance in the near future. Any recommendations? Thank you!

BBS CH-R 19x8.5 with factory runflats until they need replacing (then trying for a 255/35). Added a 12mm spacer front and rear and sits really nicely. Just need a combo of some coilovers or lowering springs and some meatier tires.

If you're in Canada you got to check out www.wheelsnearme.ca - just got some wheels and tires from there and it came in 2 days.
