Suspension and spring rates

It's technically autocross but it reminds me more of a time attack style course.


I have a very big aid with the A7s keeping me under wraps alot. When I added more negative camber it helped plant the rear alot more for me even with my street tires.

On the rear the wheel rate is about 89% of spring rate. I use 50% when guessing front wheel rate.
If you use a 500# spring your rear spring will hanging loose on the inside wheel of a turn.

On the skid pad rear inside was in the air with the 175lb springs ! 500 was way to much !

Are you running the rear swaybar? The SS came with a 23mms - way too stiff - but the base models came with a 18mm, which has possibilities. It would allow running softer springs but still keep the inside rear wheel on the ground. In my thinking, getting the rear to keep both wheels in contact with the pavement using as soft springs as possible, then tune the front to match as it has much more adjustability. :)

Now running a 36” 6” arms front swaybar with 300lb springs. The rear I have variable rate 140/250 springs and no swaybar a 275 equivalent front rcomp and a 295rcomp in the rear. 1/4 toe in front 1/4 toe in rear.

lost the ability to settle the rear with throttle when I changed from 150per inch to the variable spring. The variable ramps up to 250 and then more when the bump stop makes contact. Which seems kinda like what a swaybar would do but without the effect of pulling the inside tire away from the pavement.
