Ackerman steering block :
A = aggressive steering, good for technical track
B = neutral
C = smoothest steering, good for sweeper / high speed.
Rear upright (upper link) position :
More angle = more grip, more side bite, more body roll, suitable for low grip
Less angle = less grip, less side bite, less body roll, suitable for high grip.
Sorry Jay and VWO, i agree with this dude 100%. You guys are confusing roll centre with centre of gravity! A roll centre is a theoretical point around which the chassis rolls. The amount that a chassis rolls depends on the roll axis relative to the cars centre of gravity (C of G). The closer the roll axis is to the centre of gravity, the less it will roll. The further away it is from the C of G, the more the car will roll. This works on the simple principle of mechanical advantage, and moment arms .. It's lika a lever. For the sake of this excercise, lets treat a Bolt as our (C of G), and the handle of our lever as the roll centre. If you had a lever with a short handle, it will be more difficult to untighten the bolt than if you had a lever with a long handle.
The Roll centre sits below the centre of gravity on cars, hence they roll whilst cornering. This is the opposite to Motorbikes. A Motorbike's Roll centre is above the C of G, and thats why they tip into corners.
In conclusion, the greater the distance between the C of G and the roll centre on the Mugens happens to be the "A block". Hence, this would cause the most body roll (traction). The shortest distance between the C of G and the roll centre is the "C Block" and this will allow the least body roll..
