*laughs* It was a joint effort....
Stiffen rear, make front grip (camber kit) and you'll tend towards oversteer... How? Basically what you're doing is letting th car 'lean' on the front tyres more while letting both inside and outside wheel get a fair share of grip despite roll and controlling the body roll with the rear of the car. which does tend to decrease the total grip across the back end....
If you stiffen the front end it'll tend to slide more as the grip goes away on the inside tyre much more quickly....
It's easy to explain with a toy car
FWD and RWD respond in the same way except the big change is how the grip is changed by motive power (right boot).... On RWD you can pretty much control rear grip with throttle hence stiffing front is usually quite effective....
