If anyone is interested in Ryan Stewarts set up that we used during the WKA Grands in Dousman, WI here it is...
We tested various combinations of things through friday and saruday and by Sunday we clearly had the best kart in HPV Heavy. I feel that if we would have tried this set up on Saturday we would have had a shot at HPV light as well. We were not as good in Yamaha Light and Heavy yet we ended up with a 2nd and 3rd respectivley...but there is definitely more there.
ZX32A chassis, 2 bearing 1000x50x2-M, 100 hub right side, 85mm hub left side, rear track at 54" with standard Freeline Magnesium wheels. Tillet T11 seat, 60 and 61.5, 21.5, and bottom of the seat flush with bottom of the frame rails. One seat stay each side all of the bolts tight. Hard front bar (I took a 1040x30x2.5 axle out of the trash and made a torsion bar out of it), spindles in the middle, 1.5 degree caster in, 2mm positive camber and 2mm toe out, 100mm front hubs all the way in.
The condition of the track was quite sticky and if you have never been to Dousman it is a fairly smooth, fairly narrow, very tight course with 11 turns and the straight is not really all that straight. We struggled a bit with a hop on the exit of "the boot" and the harder we went with the axle the better. I tried an extra seat stay on the left side which helped the hop but also slowed it down. I was tempted to test the side rail, but, I think in the end it would have created a push in the hairpins. I hope this helps...Also we ran a similar set up in SR. Sportsman Heavy on an RX30 with virtually no practice and were also very quick. If I could do it over again I would have ran an M axle and no seat stays in the sportsman and I know that it would have been even better.
