Superformance chassis set up

[ramey]

depends on what you want to do. i have 1024. it had more bump steer than steering travel, and the roll centers were about 10 inches underground when I got it.... not kidding. it also has negative ackerman. and the mustang ii has tons of SAI which destroys handling in tight turns as it dials in positive camber and jacks weight when you turn the wheel.

pretty much the worst possible front suspension anyone could ever dream up no matter how hard they tried. and the handling was what you would figure.

strange, as the rear works pretty well.

so i've been looking for custom spindles, but till then using 2" drop spindles along with redrilling pickup points, grinding on them to reduce the negative ackerman some, and making custom steering rack mounts and spacers to get the bump steer under control. Now the roll center is reasonable, it has about zero ackerman, 4 degrees of negative camber, 5 degrees of caster, and about 1/4" toe out (partly to compensate for the ackerman).

the rear I keep about 1 degree negative, with just a hair of toe in.

this works pretty well for autocross, but would be too aggressive for faster tracks, and will wear the inside of the fronts pretty badly on the street.

voyager's setup should work pretty well on the street.

if anyone knows where i can have some offset lower ball joint spacers made for the spindles, that would kill the kingpin and ackerman issues all at once, so I'd appreciate any input.
