    Can you confirm the front and rear offsets of your wheels?

    We're going to measure them to be absolutely sure, because from what I've looked up there can be variations. Will let you know ASAP.

    Confirmed by measuring or looking at the specs on the wheel?

    Well, there is no way a dude in his garage with basic hand tools would measure offset to that level of precision. And if he did he would likely round up. My guess: he guessed. But let’s see.

    Pics of the rears on a car or pics of the spec markings?

    Most challenge wheels these days are sized 18 x 10 +68 (10mm more aggressive). An 18 x 10 +78 is actually rare and I suspect an early iteration. It would be same size as standard 355 wheels.

    I will try to get some pics, and perhaps they have the tools to do proper measurements and then I can include those as well.
