Here's the deal. Ultimately, you want all the tires to work equally hard,
because that's how you get the most performance out of them. If the
fronts aren't getting hot, they aren't working as hard as the rears.
Artificially cooling or heating one end or other just disguises the issue.
And whether you like the steering presently isn't really very important,
James. Since you run a car where you have the luxury of changing all the
variables, you have a number of ways of adjusting things that aren't
available to those in less-prepared classes. We screw around with tire
pressures and shock settings as compromises to settings you can adjust
directly.
Since I have the benefit of having never actually set up a Prepared car, I
can give you the full fruits of my wisdom untarnished by dull empiricism.
Please read all the instructions carefully:
- Get your driveline set up the way you need it (HP, gears, limited slip).
- Get the front and rear of the car working equally hard by adjusting, in
order, wheel width, track, and sway bars.
- Get the tires working at optimum temperature across the tread with a
pyrometer, pressures, and alignment settings.
- Work with shocks and alignment for fine tuning and handling preferences.
- Disregard all of the previous instructions and go ask someone who
actually knows what the hell they're talking about! (Spencer, Villareal,
the Hales, Stagnaro, etc.)
