hey mate, you are correct that it is all detrimental. CAMBER Is used to correct tyre wear... when a car is lowered the wheels shift vertically off the control arm/hub.. as in the top of the wheel goes further in the arch and the bottom of the wheel goes outwards hence why severely lowered rice cars get massive inside tyre wear. This causes reduced tyre footprint against the road. A bit of negative camber is OK your wheels generally goes positive on turn ins... this is where CASTOR comes in... CASTOR is a way of DYNAMICALLY shifting camber. Adding some sort of CASTOR devices changes your camber to certain degrees dependent on wheel turn in. An example of this in motorsport is the following scenario. - You don't want too much camber to prolong tyre life on cruising so you adjust for -1.5 static camber at the front. - on incline/decline turn in, optimally you may want to have you car doing -2.5 or -3 as during turn the tyres maybe flatter on te road surface during said incline/decline - CASTOR is a compromise in that its like a mathematical exponent... static camber stays as -1.5 when cruising straight, but the moment you turn in camber shifts to -2.5 TOE you may have all heard of the term TOE IN or TOE out. it is simply that... think of you feet... when your toes are in, it points your feet inwards, and opposite when out. when your car is generally turning to the left automatically it maybe because the left front wheel suffered toe out misalignment as a result of very spririted driving. CAMBER/CASTOR will NOT cause your car to turn into a direction, it is simply a function of TOE. But you guys are right, most vehicles even performance/sports ones do not come with camber/castor adjustability from factory hence the aftermarket parts available. TOE is adjustable on any car and is the only thing correctable when you take your car for wheel alignment. it is adjusted through a shaft that connects the hub to the steering rack. Most people who pay the ~$70 to get an alignment are wasting money.. someone coming in asking for "an alignment" doesn;t sound very knowledgable and very easy to scam money from. WHEN you do go for an alignment, be specific as to what you require and ALWAYS ask for a before/after printout of their laser calibration. Be specific when you ask for an alignment... I want this much toe and this much camber, etc.... Hope that helps...
