ET Question on APEX EC-7s for XI
 

Thanks for checking in on my question I have discussed this with Ryan at Apex and we still have not come to a consensus he reccomends:

EC-7 / PS-7 https://www.google.ca/url?sa=i&rct=j...57667614386754

Front - 18x8.5 et35 - 245/40/18
Rear - 18x9.5 et43 - 275/35/18

Another reccomended

>EC-7 (not available in ARC-8 sizes until 2016)
Front: 18x9et31 w/12mm spacer - 245/40-18 or maybe 255/40-18 with camber trick
Rear: 18×9et42 - 255/40-18...
Rear Alternate: 18x9.5 et58 - 275/35-18 [a 12mm spacer can be desirable for looks]

I had a tough chalenge since I wanted to go with an 18'' stagered setup that would fit an M5 brake setup. While being able to fit also the regular xi rear hub as the M5 rear hub is a little off (acouple of months) and also shorterhttps://lh3.googleusercontent.com/-Y...25282%2529.JPGr. So the idea is to use the wheel now and with a spacer adapt the wheel to the M5 hub.

Tire size will be 245/40 and 275/35 in 18'' as of now I have a good deal on some APEX EC-7 but size is 18x9 et42 and 18x9.5 et43
