Hey guys,
I would like to see if you guys could help me out with my measurements. In another post a user suggested using wheel adapters to fit my mustangs wheels to my BMW M4 without Xdrive;I would like a flush fitment. Car has KW HAS

The Specs
-The adapter would be 5x112 to 5x114.3
-The wheels in question are velgen forged SL7's
-Fronts are 20x9.5 ET 30 275/35
-Rears are 20x11 ET 50 305/30
-With a 20mm adapter in the front this would give me ET 10
-With a 35mm adapter in the rear this would give me ET 15
-according to online calculators both should clear brakes and suspension

My questions
-would these new offsets be flush for my vehicle?
-Is there any possibility of needing to shave off my studs? My wheels have pockets in the rear.
-The center bore of the mustang was 70.3mm the g82 is 66.5mm does this matter?
-Am I missing anything important?

Thanks for any and all help guys! Sorry for my lack of knowledge. This would be my first time using wheel adapters.

That's critical, the adapter must match the new wheels and your hub perfectly, including the centre bore.
You might need to trim your studs, just figure out how much they stick out from the hub and see if the pockets in the wheels are deep enough with the 20mm adapters.
No idea if they'll sit flush, that you have to figure out yourself.

Thank you for all the help! I've done the math so far and my research using IND's wheel spacer thread for reference for my fitment. I just had one last question if you don't mind me asking. My wheels do have pockets on the back side of the mounting surface so that the OE wheel studs will fit inside. My question is how will I know if the studs line up correctly with the pockets? I don't mean depth wise I mean with the mounting surface of the wheel? Is it because once I bolt on the adapter to the car those studs are in 5x114.3 orientation and will fit behind those pockets? Apologize for my ignorance and lack of knowledge but I appreciate all the help/insight you have provided me !

In case you wanted to know the specs;
-Fronts will be using a 22mm adapter for ET8 fitment
-Rears will be using 36mm adapter for ET14 fitment

The wheels I will be mounting are:
-20x9.5 ET30 (CB70.6)
-20x11 ET50 (CB70.6)

Bronson investments will be making the custom adapters with conical style bolts. Accelerated Motion on youtube has been very helpful as have you sir!! Thank you!

Post a Pic of the back of the wheel, odds are he pockets are big enough so you don't have to worry about that.

You should be good, plenty of clearance.
