^That statement is also totally confusing. I'm fully aware of Kevin's setup, but I can't grasp your comparison. Kevin's running 18x10.5 +26s, so are people with 6th gen accords running +12 or +15 offsets at those sizes? If not, then there's no need to refer to +26 as a "higher offset" if it's not really higher than the typical offsets being used at or near that size.
It sounds like you're trying to say that in general, a 10" wide wheel with an offset in the mid-20s with a lip "gives the same poke" and "also gives more wheel underneath the chassis" compared to what I can only assume is the same width wheel with a +15 offset without a lip? It would then have 10mm less poke (not the same), so of course it'll tuck into the chassis a little more. I don't understand what the the lip has anything to do with your statement. Whether the car has a step lip, a reverse lip, or no lip...width & offset are independent of that. What I hope you were trying to say was that a wider wheel with a little higher offset is better than a narrower wheel with a lower offset, which I would totally agree with you on. I'd prefer a 10" wide wheel with an offset in the mid-20s all day over an 8.5" wide wheel with an zero offset. Still, lip type is irrelevant there.
I also hope people realize that one person's setup won't fit the same on another's, especially Kevin's. Ride height, alignment specs, tire brand/model, and variances in wheelwell modifications will make a setup that's pushing the limits on one car incompatible on another car.
