Camber:</span>
Function:
Adjusts the vertical angle of the wheel (the amount of tilt towards or away from the body). Some amount of negative camber which tilts the top of the wheel into the body is the norm for high performance cornering.
Optimum:
Maintains a flat tire contact patch during cornering to maximize grip for highest possible cornering speed. For street driving more than 1 degree negative camber will prematurely wear out the inside treads. For racing it's common to use as much as 3 degrees on a road course.
Too Little:
The deflection of the tire during corning will lift the inside edge of the tire off the track reducing the contact patch size.
Too Much:
The outside edge of the tire is prevented from reaching the track surface even under cornering, which reduces the tire contact patch. Also limits the contact patch available during accelerating and braking. Straight line driving will be less stable.
for all of you straight line "racers", you want 0 degrees.... straight up and down, that will give you your best contact patch
for people who like to carve through the twisties regularly, and tend to corner a little harder than normal people, you could definatly get away with a little extra camber... i wouldnt go quite as aggressivly as i would on a track car, but a few degrees negative will help you more than it will hurt you... and if you are cornering hard enough to use the outside edge even with the aggressive camber setting you will still maintain decent and even tire wear (actually better than if you didnt have enough negative camber)
for track use you really should have an adjustable camber kit and tune it for your specific needs (the settings will be different for every track)
so if you notice that you are rolling and wearing the outside edges and your tire pressures and alignment is good... you need more negative camber
if you notice that the inside of your tires are bald and the outside still looks new and your alignment is good... you need less negative camber
so as you can probly guess there is no perfect number that will work for everyone, every car, or every situation
camber is a good thing, IF YOU USE IT.... and 9 times out of 10, in all honesty, "too much negative camber" is just a nice way of saying you corner like a bitch
