I just scaled my kart for the first time after getting it set up. The numbers came out great for a first time. I have 64% cross, 56% weight at the rear, with 44% at the front. The only thing I don't have is rear stagger. I'm wondering if anyone has used there oven, and air pressure to heat and expand the tire, then cooling it quick with cold water? I would like 3/4 inch of stagger if I can get it, and I technically have a 1/4 inch now just with more tire pressure in the right rear. If this works I'd like to try it, and also I would hope that it doesn't throw off my cross percentage, thanks
