The VW guys started using narrowed front beams for tire clearance/wheel fitment - not much available in 5x205 bolt pattern. Then some of us started stuffing big tires on them - mine sits on 17x7 wheels intended for a new beetle, 5x100 bolt pattern. The 205/45x17 tires run fender lip and inner fender on my car, with a 4" narrowed beam, 2" per side. The drop spindles also add about half an inch to track width each side, adding to fitment issues. I'm tucking wheel though, so that has a lot to do with fitment issues. Any higher looks the ghey though.
Swing axle and link pink beam would in fact suck for a track/auto-x car, but I figured I should put the car to some sort of use
My understanding is that STX requires a cat, and there's no way I'd be competitive for years in SM/BSP, especially with the combo of me as driver and my daily WRX as the car.
