14" tire/wheel combos for autocross

My autocross Vee has always presented challenges regarding tire and wheel combos. I need a bit of guidance--



First off, 4x130 has to be the worst pattern for wheel selection (beetle & 914 only) and 14" has to be the worst size for tire selection. I know, hindsight and all...



Previous combo on all 4-

14"x8" Diamond Racing steel wheels with 225/50 Hankook Z214's C71

Impressions- Had these built by DR, HEAVY wheels, good grip in fast sweepers. More tire meant great holeshots.



Present combo on all 4-

14"x6" unknown brand, possibly mag, 205/55 Hankook Z214's C71

Impressions- LIGHT wheels (11lbs), not enough tire for the heavy rear in fast sweepers, great in slaloms and quick transitions, more favorable offset also narrowed the car in a good way. The tire lacks meat and spins up much easier. Note: The 225 vs. 205 is a BIG 20mm, they are much skinnier.



My times for both setups have been pretty similar, though I feel that I'm leaving a lot on the table.



My challenges-

• 4 x 130 bolt pattern greatly limits selection.


• 13" wheels has required more clearancing of calipers than I'm comfortable with.


• Very limited 14" tire selection

Possibilities-

• Run the heavy 14"x8" wheels on the rear with 225/50 'kooks?


• Go to a chevy pattern on my rotors and start all over with possibly better selection? 15" maybe? $$$


• And what really has my gears turning.... 14" CANTILEVER on the 6" wheels??? Does it exist? It seems all sizes have gone the way of the dinosaur. I love me some cantilever.
  

I know I'm playing a terrible hand here, but I'd appreciate some ideas or input.
