Reply to "Wheel Alignment Question"

The more + caster you have, the more difficult it is to steer around turns.
Cars with power steering can take a little more but the wheel will still fight you.
+ caster makes the car want to go straight.
You need to find a compromise.
2-1/2 to 3 + seems to be approximately it.
Less will make the car much more squirly. More and you can't turn the wheel quick enough to steer around tight turns. 3+ would be good for a drag race car to keep it going down the track.

The profile of the steering tire effects this tremendously. Also the suspension can be tuned largely with air pressure. The difference between 30 pounds and 40 pounds is night and day.
It depends as much on the wall stiffness of the tires as anything.
These cars were not designed for 35, 40 or even 50 profile tires.
Round shoulder front tires like Pirelli CN36 make driving more civil but the car won't generate big G numbers, but that's how the suspension was concieved of.
The square edges of those low profile tires can create instant, violent oversteer, and they also enhance bump steer to a lethal level.
P7 Pirellis are a hybrid tire between a stiff wall and a bias ply tire like the Arriva.
The car is easier to tune and more predictable.

I don't know how the wide body cars are tuned but considering what I have experienced driving you are going to have to prove it to me that they are not death traps on NY roads.

...let the games begin...step right up and whip up on me...pain and degredation is what I'm all about.
