ReV, the roll center and roll axis are fixed by the design of the suspension and where the front/rear are in relation to each other .

I meant the body roll when cornering, which I'm sure you knew but are attempting to be cheeky about.

Suspension control has provied quite an education on this website over the years. Somewhere in the archives of this site are pictures and articles including camber compensators, z-bars and other attempts at swing axle control solutions. In view of the weight and components used I think our swing axle cars are closely related the formula-v. This website link provides a good summary and review of the path those folks have traveled. http://www.veecentre.com/what_is_formul ... derations/

Fixed…you say…but do realize that the position of the roll centers is a dynamic condition, so the roll axis can shift when the vehicle reacts to bumps or goes through a turn…creating a vehicle which understeers when entering a turn... and oversteers in the middle of the turn because the (front) roll center has changed.

And as stated earlier…rim width and tire cross-section can have a marked effect here !

I just put the Excel G's on my Spyder and couldn't be happier. (I read somewhere that the Excel Gs were even softer than the Gas a Justs.) $91 for all four. When I bought it, it had Boges on the front and Bilsteins on the rear. I'm 275# and I couldn't deflect the rear shocks half an inch putting all my weight on the rear fender. With the KYB's I can get about two inches of travel pretty easily.

GOLDBARBILL


Those are the Excel G's I bought, not the Gas A Justs Larry is talking about, and it's 343143 and 343144 front and rear. (Rears have two eyelets, fronts have a lower eyelet and a top stud.)
