The search for rims is a long stressful path. What's the point of finding super light options if they aren't 5 x 105, the weight savings will be moot once 8 lbs worth of adapters are used to bolt them on?
I stumbled across these Aluminum Opel 18 x 8's with 5 x 105 pattern, a 43mm offset could work with spacers (not nearly as heavy as adaptors):
I fail at google, and can't find the weight of these. I do think it would be kind of fitting to rock some Opel rims. If someone feels inspired to find the weight, please LMK what you find.
