From my meager experience at uncle skippy's place (aka
skip barber racing school), here goes. (Ed. note. this
is an exerpt from a doctoral dissertation by Seok Min
Lee, circa 1466 BC on the high performance
modifications of single seat raing chariots.)
"
CAMBER:
The degree to which the tire/wheel is not
perpendicular to the horizontal plane running through
the center of the hub when looking at the vehicle
head-on. Usually, this is a bad thing to have too much
negative? camber with the bottom edge of the tire
wider than the top edge, but when road racing, it is
sometimes a good thing because when the outside tire
becomes loaded, the weight shift and resulting lean of
the car shift the full width of the tire into contact
with the road surface. Having alot of ?negative?
camber will also exponentially reduce the life of the
tire.
CASTER:
The degree to which the front/rear suspension
upright/strut tower is not perpendicular to the
horizontal plane running through the center of the hub
when looking at the vehicle from the side. A Harley
with high-bars and laid back seating is more conducive
to high-speed highway cruising than dicing it up in
the city with the rice-rockets.
TOE-IN:
The degree to which the front/rear wheels/tires
are not parallel with the vertical plane passing
through the front/rear hub. The more toe-in, the more
responsive/twitchy the vehicle at turn-in.
DROOP:
The amount of negative travel in the suspension
(on a normal Cartesian x-y graph with positive being
in the "upwards" direction). For example, the A3
Jetta/Golf have almost no suspension droop leading to
the inner rear tire lifting off the ground during
auto-crosses/road races/high speed maneuvers while
running from cops in south-central Idaho."
thought that would take longer to wri.... i mean copy
than it did.
peace, out.
