Pagani Zonda R '09
I don't think many words come close to describing the sensation when driving this car. Its a pantomime in its own right, but beneath the skin lies something very very visceral - its raw power will devour you if you make the slightest mistake. Nevertheless, this car has some outstanding performance right out of the box, I was stunned by its pure speed and very neutral balance through corners.
However, the mountain of torque and power meant throttle control had to be as precise as a surgeon, if you're not using a wheel or anything beyond a standard controller, it may prove difficult to actually pilot this thing around corners without spinning out in a flurry of screams and spasm. The most alarming issue I found was exit-oversteer, and though turn-in response was good it did however seem reluctant on entry.
The first was rectified by adjusting the LSD for a lower acceleration sensitivity, to compensate the initial torque was raised so the pre-load would stay similar. Braking was also improved by increasing decelerating sensitivity.
The latter was rectified by dropping the front ride height slightly more than the rear. Overall agility was improved by increasing spring rates and turning up the dampers. The factory installed anti-roll bars were adequate on undulating corners, but hindered the car's performance on tight hairpins or chicanes, so they were remedied by stronger after-market parts; with a rear bias.
The car is very rigid by nature, so not much camber adjustments were needed. That said, some negative camber was still added for improved grip through corners and some toe-out was introduced for better turn-in response.
The result of all this means the car retains its neutral attributes, but it is now easier to apply throttle through the corners and the risk of a spin-out is reduced.

All testing was conducted on Suzuka, Personal Best is 1:56:619 with exact specifications from above. Had I modified the engine to give more HP and swapped for some slicks, then we can expect times comparable to the ZR-1 even.
Enjoy!
