camber & toe-in/out

[SodTiwaz]

ok i know what camber is and what toe in/out are, however ive yet to find a decent explination as to what they do...right now i have my front and rear camber at about -1, i have 0 toe possibly a slight toe-in from what i understand toe-in will make responce slower and it will over steer, toe-out quicker responce but under steer. unfortunately that means very little to me the only thing ive noticed that camber does is wear the inner part of the tire instead of the center...would one of you knowledgable ppl fill me in on what it all means?

More toe in will make the car less sensitive but not over steer. More toe out will make the car more responive and sometime loose and can cause the car to be unstable at high speed. From what I've used it for, I don't think it has to much of an effect on overal steering other than response. But if you have a really bad indersteer toe out can help to get it into the turn faster. More camber is about the same as toe in but it will help to ge through rough spots better, mostly in turns. Less camber will be more responsive, have a little more traction, and go trough bumps a little worse in turns.

ahh ok so its all about traction in turns...thanks for your reply http://www.rccaraction.com/ubb/smile.gif

And just to add some more...look at a real car...notice how the front tires seem to lean in towards the engine (negative camber)? Well, when your going around a corner, the car still wants to 'push' straight (physics), and in doing so makes the cars suspension, such that when this is happening, more of the outter tire is coming into contact with the pavement. If you've got your truck/car in front of you (I have a RC10 GT), push down on the car, notice how the tires begin to lean in even more now. That was just to illustrate how the suspension geometry changes. As for toe in/out, steering responsiveness is a good explanation, but to add...this causes the tires to 'scrub' the pavement, so it adds some resistance (not much though to these little cars) to its rolling abiltiy. If you actually just search the net for real AutoX cars and setups...most ideas can be applied to our R/C cars.

well i'v got a tamiya TLO1 really nice and hopped up and when i first started off i didnt know **** about this so i asked a guy at my local track and i learned how to fix my MAJOR understeering problem and i only have toe in/out so i had it on 0 deg. then i put it about 2 deg. WOW HUGE diffrance and about it slowing down the cars speed it only REALLY makes a diffrance if u put it past 3 deg. so experement and it should work out cyas

Actually i was kinda doing what you said in my head thinking about how when a car turns centripical force tries to keep it straight...hence putting force on the outer tires (it seemed logical to me that more toe-in would help cornering as the wheel/tire that was actually on the ground already had some inward toe-in)
and for the camber i was pushin on the suspension and did notice the tires get even more negitive camber when a downward force is applied though i had no idea what that ment traction wise...
