I vote Minlite cuz they are simply the chit.
Not sure about the strength or weight of the generic copies, but I think most are cast and somewhat heavy, which means they aren't hugely strong, but they won't fold up when tossed around like a drag wheel might. I know that imincarn8 has said his VWW wheels feel a bit porky, but the choice of tires makes up for the extra weight.
I'd say that 15x9 with 4.5 back space would fit just fine, but tire sidewall could get a bit close to the rear spring segment.
An option not mentioned here is going with some oval track wheels. I'm talking real racing wheels, not the weigh a ton copies offered by AR, but something from Diamond, Aero, or Bassett. I scored a set of 15x8 and 15x10 Aeros at their clearance sale for $25 and $35 each. The fronts weigh 18# and the rears are 22#. That is in aluminum wheel range from a steel wheel with tough as nail centers. Choice of colors in black, grey or chrome.
Also don't forget that real Minilites are still out there and available. I had a set quoted about 6 months ago and a pair of 15x8s and a pair of 15x10s with custom backspace came in at only $1500 shipped to my door. Only drawback is they only come in 15" diameters.
