Its a roller!Ive got the rack on,it to long for the set up but the buggy only has 5'' of travel in the front so bump steer will not be to big of a deal.I set the wheels up with 3 deg. of negative camber, the frame has 8 deg.of rake and the spindles are set at 9 deg.caster.
With it set up this way if its turning to full lock,the inside tire the inside goes to 2 deg of positive camber and the outside goes to 8 deg. of negative camber.This makes the tires lean into a turn like a motorcycle,and it has much better traction in turns.If a front end has no camber change in a turn the front wheels have a tendency to lean to the out side,this makes the front end push or under steer.The camber change can also be built into the aarms by making the top aarm shorter than the bottom,and or by the spindel longer than the mounting points on the frame or the other way around.
The scrub radius is zero on this buggy,the spindle mounting points are uneven(leaned in at the top).If you were to draw a line from top to bottom of the mounts it would point to the center of the tire.So when the wheel turns from one side to the other the tire pivots in one spot on the ground.This is good because when the wheel hits a big bump it does not jerk the steering wheel the wheel just goes over with out much feel in the steering wheel.
With a big scrub radius the wheel will turn around the king pin or spindle instead of pivoting in one spot on the ground.This will give more jerking in the steering wheel when hitting big bumps.
Ill get some pics. up tomorrow.
