I dunno about the +2 A-arm recommendation for hare scrambles\woods racing. You want a narrow front end, not a wider one. Your front end, from edge to edge of the tires should be around 47 inches, 46 would be better. 4:1 offset front rims help with bump steer issues and Razr 2 front tires, size 21x7x10 are by far the most used front XC tire and size. A steering damper is a must have for all racing. A +1 or 2 anti-vibe steering stem is nice to have and a set of Flexx handlebars would be ideal. Handgaurds too. Narrow front and rear for xc racing. A -1 or -2 swingarm will allow the quad to steer better because it shortens the wheelbase and allows the front end to come up easier to get over obstacles. xc quads are have a narrow stance, get those 4:1 offset front rims with a nice set of Razr2 tires on em and measure the front end's overall width. You want to be around 46 to 47 inches wide. Any wider than 48 inches and your giving the advantage to the guys your racing against.
