Reply to "Speed Stability"

As-stock, they're pretty stable, but a better 'feel' comes from more caster than the factory used. The std front end is limited in its caster relative to most other similar cars. Offset a-arm bushings, all the caster-shims on one side of the upright and even machining one side of the upright still only gives marginal caster for really high-speed work. And of course, a front spoiler of your choice or at least a 3 degree nose-down 'rake' will increase stability. Note than at 100 mph, none of this is really needed; at 140 & above, all of it is. Most well-tuned Panteras with a stock engine will run 150 at least for a while, so this is not a theoretical requirement unless you only drive within city limits.
