The problem with the Cragar (and Torque Thrust) wheels is they are a five spoke design. It's tough to get the same look with a four lug wheel since it limits you to four spokes. They did make some four spoke/four lug, but it's almost always in a 13" rim size. I agree with you on the Outlaws, I was thinking more like the old Ansen Sprint (although Summit only shows it in 15x7 with a 4 x 4 1/2" lug pattern). I've attached a pic of my old 70 with the slotted mags on it. Just never could get into the Cragar SS style and Torque Thrusts were crazy expensive back then.
I know what you mean about the mounting and balancing. I get my tires from Tirerack, but I have an independent tire shop near me that charges $14 per tire for mounting and balancing. Even if you get a good deal on tires online, if you can't find a shop with a reasonable m/b rate, it wipes out whatever savings you get online. Plus, as I found out, major chains will charge more for the tire and include mounting, but balancing and valve stems are extra, usually still at $15 per tire. Bring your own tire in and they want $20-$25 per tire.
I don't have any experience with the Uniroyals, but I can tell you that the Kumhos will really surprise you. I've used various Kumhos (Ecsta ASX, Solus, Venture) and have not been disappointed in the least. I don't buy my tires for 'extreme dry weather traction'. We have rain, snow, and ice here and it will sneak up on you. Give me something that will get me home safely during a pop-up thunderstorm or even snow. The Kumhos have never disappointed me. The cheaper Solus tires on my Opel have more grip in the wet than the previous Pirellis did in the dry...and the Pirellis were wider. Even my Safari van has trouble sliding in the wet with the Ventures on it.
The only down side to the Kumhos is that I usually get only half the tread life out of them. I don't think that matters on a hobby car. Most of the time the tires will get hard and start cracking before they wear out. On my daily driver's, I've paid a lot more for tires that didn't perform half as well.
