What's the point of more power if the car cannot handle the twisties. If the intention is drag then happy days but if it's fast road hitting the load peddle then braking like a Micra owner on a Sunday drive "corner in" belays the point.
There's loads to explain, maybe i should open another thread but by design the cars chassis has a frequency and believe it or not it's tuned to our natural frequency, when the car is modified it needs to be calibrated to suit the owner and his/her intentions, in addition the tyre wear factor is examined......
My natural frequency is quite low so i would have problems driving a car like the Evo X, whereas someone like Button would say it handles like a bit of a donkey, this is not because he is a F1 driver, it's because he can cope with much more input "yaw" and he finds the car unresponsive.
The domestic car is setup to understeer, it's chassis positions encompass the boy/girl racer and grandma, it's in the manufacturers interest the car has a global inert handling package, some would argue the HP but think about it the HP is "available power" not handling, push that to the limit because you want to feel the HP and you get it wrong the car understeers.
Changing the chassis positions changes the tyres saturation limits..... your thinking WTF is he on about now?... Well that's another topic methinks.
