Roll center height for Superformance

[vatdevil]

Has anyone here calculated (or know) the roll center height for Superformance? I'm going to calculate my cars current roll center and would like to have something to compare to.

unfortunately, stock #1024 was about 18" above ground in front, and about 5" rear....

now it is about ground level in front, after a bit of work. drop spindles. redrilling pickup points, etc.

the only way to do it really is get the car on a rack, on some graph paper, and use a plumb bob and soft ruler to mark pickup points in x/y/z dimensions.

Ramey,
Perhaps you could provide a more detailed description of how you achieved your results. I have been thinking for a while that SPF's look too tall and have been wondering how to make mine lower. Do you have a source for the drop spindles, etc.
Thanks,
Bob

18 inches? You calculated that by connecting the instantaneous center point
with the tire contact patch center?

Last week in a different thread you wrote: " i have 1024. it had more bump steer than steering travel, and the roll centers were about 10 inches underground when I got it",

I'm confused.
