This is like tracking, but for the back wheels. Thankfully, unlike Caster and Camber, you adjust the tracking on even the most basic of cars by winding the track rod ends in or out. This is something that can need altering after you clip a curb or hit a particularly unforgiving pothole. Needless to say, the opposite, with your toes touching and your heels apart, is toe in. Now keep your heels together and twist your toes away from each other. And the best way to think if it is to indeed use your toes. This is the most common suspension term, and it’s probably something you have had altered on your own car at some point. You’ll also lose a lot of the car’s handling ability as the wheels will in effect tilting into the ground when you steer. Positive caster is the way to go, as you’ll get greater steering feel, improved turn-in response and greater stability when at speed.īy having too much negative caster, you’re already pulling the suspension back into the car, so when the car is moving, the forces are amplified, and the suspension/tyres are put under much more strain. Positive caster would be to swing the suspension forward, while negative would be to pull it back into the car. This is the backward or forward inclination of the suspension. See how individual suspension components work Caster But even so, setting it up is something best left to the professionals. When cornering, the wheel is pushed straight in relation to the vertical, and as more load is put on it, more of the tyre can touch the road, so more grip.Īs such, a nettle bit of negative camber is never a bad thing. If you have negative camber, you get the opposite result. If you have a lot of positive camber, the car would be more stable in a straight line, but awful in the corners, as the force of cornering would push more weight over the wheel, which would already be at an adverse angle to the road. The amount of camber can drastically change the way a car drives. Take a look at the diagram lower down for a visual explanation. In the case of negative camber, the top would tuck into the car. In the case of positive camber, the top of the wheel would pull out from the top of the car. It can be measured as positive or negative. CamberĬamber is the inclination of the wheel on the vertical in relation to the ground. So, what’s what? Handily, we’ve put a little guide together for you. It’s important to make sure everything is dialled in perfectly, otherwise your car will drive in a direction you don’t want it to, it will chew up tyres and it will make your car pretty damn unpleasant. There’s an art to setting suspension up, and without it your car will drive horribly.
