Probably similar, but not identical.

I dunno for sure; I've never actually compared them. I'll
assume that the spreadsheet is right. There's certainly not
much sidewall there...

That sounds about right.

Not exactly a concern of mine, since this car is not street legal.

Other than the fact that they stick like glue? BTW, most
current bias ply race slicks use the inch measuring system
(ie, 23.5 X 9.0 X 15) and not the metric system (ie 225/50 X 15).

No rubbing on my car, but I'm running 3/4" spacers on the front
to increase the track width. They do protrude from the fender wells
even though the fenders have been flared.

I'm using 15 X 7" Panasports; I'm afraid that I don't remember
the backspacing off hand, but since they are currently sitting
in garage with no tires I could easily measure it for you if
you'd like. They are similar in backspacing to the old, factory
Silverstone wheels, with all the new width added to the outside.
hope that helps,
