Somebody needs to clue this old guy what "concave" refers to when we're talking about wheels. All I know is what it takes to fit (or mostly fit) wide wheels. Beyond that, I haven't ever tried to describe the wheels.
Anyhoo, I do have an update . . .
Previous 3-season, autocross, and track day setup: 255/45-18 Goodyear Asymmetrics on 18 x 9.5 x ET+45 SVT/GT500 wheels.
New track day setup: 285/35-18 Michelin Pilot Super Sports on 18 x 11 Forgestar wheels (front and rear). The tread is entirely under the sheetmetal, but there isn't even 1mm of offset to spare on the strut side to tuck them in any further (I ended up making an 0.025" thick spacer - that's 1/40 inch, not a mis-type - to eliminate a rub).

Lol just a newer style wheel.

I know exactly what concave is "youngster". I'm also a member of other forums and unlike this forum the are hundreds of pics of guys that went from deep dish to concave style wheels. I'm also a member of one of the biggest Mustang clubs in Texas and its the same thing. Concave style wheels are the new thing.

Yes, I realize that 'concave' is a fairly new term. What's still not clear is exactly what it is trying to describe. Can it be measured? I'm a member of several other forums as well, but I'm into the cornering, handling, and track day driving segment of the automotive hobby as opposed to car shows and appearance discussions.

Today we engineer our wheels using precise measurements and testing to ensure a maximum concave wheel without sacrificing the structural integrity of the wheel. Our concave depth is up to 3.5 inches depending on the wheel design.
It also allows the wheel to look larger than a wheel with a traditional outer lip since the spokes extend to the rim edge. With our new flow forming technology wheels, it now allows us to offer different widths while producing a lighter and stronger wheel. So now we are a mid-concave 9.5 width in addition to our usual deep concave profile of 10-now 12" widths.
I hope this helps some.

I'm guessing that's the key phrase, that the outer faces of the spokes are visibly sloped back away from the plane of the flange along sort of a cone or bowl shape as you move radially inward toward the hub?
Have to admit, I never gave this aspect of wheel design much thought. Obviously not enough to associate any one-word description to it. Mostly, just "is the wheel the width I want", "do the spokes look strong enough for cornering loads", "are there enough of them", and "are they nice, simple shapes that will be easy to clean"?
Thanks, Mike.
