Here is what i found & figured out, so can be useful for somebody

-------------------------
225/40/19 8Jx19 ET27
255/35/19 8.5Jx19 ET40

ALPINA B3 19''
-----------------------
255/35/19 8.5Jx19 ET28
265/35/19 9.5Jx19 ET38

SUPRA A90

255/35/19 9Jx19 ET32 +7mm spacer

20'' Wheel & Tyre combination
STOCK 20''

ALPINA B3 20''
-------------------------
255/30/20 8.5Jx20 ET28

Next is measurement for wheels to be flushed with fender,Xdrive compatibele STOCK M/H&R/Eibach lowering springs + S2VF Adaptive M chassis + S2NH M sport brakes:

FRONT WHEEL SETUPS FLUSHED WITH FENDER

8J ET27 Poke 74.6mm inset 128.6mm Backspacing (in)= 5.56'' *STOCK FRONT WHEELs NOT Flushed with fender M340iX
8.5J ET22 Poke 86mm inset 148mm Backspacing (in)= 5.62''
9J ET25 Poke 89.3mm inset 139.3mm Backspacing (in)= 5.98''

REAR WHEEL SETUPS FLUSHED WITH FENDER
---------------------------------------
8.5j ET40 Poke 86mm inset 30mm Backspacing (in)= 6.32'' *STOCK REAR WHEELs NOT Flushed with fender M340iX
8.5j ET20 Poke 88mm inset 128mm Backspacing (in)= 5.54''
9J ET25 Poke 89.3mm inset 139.3mm Backspacing (in)= 5.98''
9.5J ET32 Poke 88.7mm inset 152.7mm Backspacing (in)= 6.51''
10J ET38 Poke 89mm inset 165mm Backspacing (in)= 7''
10.5J ET45 Poke 88.7mm inset 178.4mm Backspacing (in)= 7,52''



So based on above data from links and google i think i will go with next fitment:

20x8.5J ET22 / 20x9.5J ET32
OR
20x9J ET25 / 20x10J ET38

I got final answer from WORK, for my setup, Adaptive drive + M sport brakes 18''... for concave wheels at front i need to choose R Disk (Big Caliper / Flat Spoke) and for rears A Disk (Standard / Mid Concave)

That is it... now lets order them
