I need some help with wheel fitment/selection

I'm looking for a replacement set of rims for an F33. The size I'm looking for is 18x9 on all four corners. I'm not willing to go to 19" rims due to the harsher ride from the shorter sidewalls.

I currently have Style 658 18x8.5 et47 rims on all four corners (12.05kg/26.57lbs each) with Michelin Pilot SS 255/40/18 tires. There are 10MM spacers on the front (the tires were very close to the springs with no spacer) and 20MM spacers on the back. The fit is perfect on the back (effective offset 27MM) and just a few MM in on the front (effective offset 37MM).

My preference is forged to get maximum weight reduction.

I was looking at the Apex VS-5RS, but they're only in -30 offset, which would push the tire out by almost 1/2" (not that much space available). I'm thinking I'll need a -35 offset as a minimum.

They'll also need to clear the 380/370 rotors - an upgrade that may, or may not, appear.

Any suggestions?

TIA

I see no reason the +30mm offset shouldn't work. Apex says they fit, why do you assume they won't?

Apex says they fit, with 245/40-18 tires. The tire I'm running is 255/40-18, which Apex says needs a camber adjustment to fit properly.

Also, the pictures I've seen that show top or front views of these wheels on an F3x show a bit of poke. I'm looking for a flush fit.

If I'm going to be paying this much for rims, I'll be getting something that fits the way I want them to fit. Apex doesn't do that. If they had an 18x9 et35 rim, I'd have them already. Unfortunately, that size/offset doesn't interest them.

Fair enough.

Best of luck in your search.

So far, I've found one company that will create wheels like this:

https://bcforged-na.com/

They're a bit pricier than the Apex, but they'll fit correctly. Still looking for other options.

The wheels arrived today. They look great and the packing was superb. They weigh in at 19.25 pounds.

I hope to get them mounted this weekend.
