If those specs are indeed correct, I would recommend spacers of 15mm front / 20mm rear. The OEM Coupe wheels (Vasekvi, et al) are 17x7 et55. For comparison purposes to the 18x8 wheel, those specs would equate to roughly a 17x8 et42.3 (i.e. the outer lip face would be in the same respective location compared to a 17x7 et55 wheel).
More conservatively, you could go with project kics 10mm spacer front. I hope that makes sense
.... My personal preference would be 245/20
/18 tires with 15mm F / 20mm R spacers
BTW, great thread Kevin
Did you mean 20 or 30?
Thanks for the response. Now that I know the offsets, I drew it out in CAD. And you were right, they would both stick out the same distance. So, I'm actually thinking about running 20MM up front, and 25MM out back.
