Ik vind het een goed initiatief. Daarbij raad ik echt iedereen aan onderstaande site te checken en door te lezen. Staat echt zoveel elementaire info op wat voor de zelfrespecterende circuitrijder tot op zekere hoogte basiskennis hoort te zijn. Reuze interessant dus en je hoeft ook Bert M3 niet iedere keer lastig te vallen met een onderstel vraagje.

Dit is bijvoorbeeld al zo'n mooi stukje proza.
''If the car is heavier at the front, that is, the CG is near the front, obviously the front tyres shares most of the centrifugal force thus they have to generate larger slip angle thus larger frictional force to counter the centrifugal force. As a result, the front slip angles exceed the rear's, and understeer occurs.
On the contrary, rear-heavy car has larger slip angle at the rear, thus introduce oversteer. Similarly, we can find a 50/50 balanced car having neutral steer. This is our choice for optimum handling. We don't really need oversteer in this case, because such oversteer is not controllable, unlike power oversteer which we have found in RWD cars.
The result favours front-engined, RWD cars (FR), which is easiest to achieve 50/50 F/R weight distribution. ===> E34 / 130i :banaan:
Mid-engined, RWD cars (MR), with its slight rearward weight bias at about 40/60, is slightly inferior in here. But remember, its superior steering response, steering feel and dynamic balance are probably more than enough to compensate.
Front-engined, FWD cars (FF) is the worst in here, and far worst. As all the heavy mechanical parts - engine, transmission, differential - hang over the front end, the front axle normally takes up to two-third of the weight. This tends to create heavy understeer. In addition to the understeer generated by the FWD configuration, the result is even worse. This require a lot of work to do in the suspension geometry and steering mechanism for compensation. And there must be some trade-off. Take an Alfa GTV as an example. It has to install an ultra-quick 2.2 turns steering to counter understeer, thus requires quite a lot steering effort. If power steering were increased, steering feel must be deteriorated. The multi-link rear suspension was also probably chosen for compensating the understeer because the geometry is more tunable than the original MacPherson strut. ''
