Since you have an LCI E92 the wheel hubs extend 8mm further than a PRE-LCI car. This makes it much harder to fit a lower offset concave wheel in the rear.

Transferring the 225/40/18 and 255/35/18 tires makes things easier since these are narrower tires than we usually suggest. It is possible to fit an 18x9" ET31 profile 2 concave wheel in the front but your 225/40/18 tire will have a significant stretch over the wider 9" wheel compared to the 8.5" we initially suggested. The 18x9.5" ET35 and ET43 use the same concavity profile 2 and will look the same. The 18x9.5" ET22 is a more concave profile 3 wheel but it is too low of an offset wheel on an LCI E92 and you would need to heavily roll your fenders, maybe even flare them.
