20x 11 setup

I have the following on my F83

Wheels:
Front wheels Vorsteiner V-FF 103 20 x 9.5 et22
Rear wheels Vorsteiner V-FF 103 20 x 10.5 et34


Tires:
Front wheels Michelin Pilot Super Sport 255/30R20 (92Y)
Rear wheels Michelin Pilot Super Sport 295/30R20 (101Y)
TPMS

I have zero issues with rubbing and I’m lowered on HAS coil overs

I am buying new rims and want to move the rear to 20x11.

Keep the same 295/30/20 tyres

Will I have a problem with rubbing inside or out? And how should the offset change to get a good concave?

Thanks

Not sure what wheels you're getting so I'll answer in general.

Most custom forged wheel manufacturers will have 3 or 4 concave profiles: flat, small concave, medium concave, deep concave.

The great thing about the F8X is that it's easy to achieve a deep concave. Whether you go with a 20x11 +40 or +35, the wheels will most likely have the deepest concave face that they offer.

You "can" specify a flat face profile... But I don't see why anyone would do so.

Getting a deep lip is a bit harder on the F8X. This is all due to the big ass brakes on the F8Xs — no complaints about that though.

Thanks for the advice. I’m looking at rohana wheels rfg3 wheels so how do I decide 35 or 40?

PM Jimmy at SignatureWheel and ask for his fitment advice. He hooks you up with great info regardless of brand or buying through him.

Total guru! Nice as can be.
