Standard Rear vs Variable Rate cargo rear springs
« on: September 24 2012, 10:28:45 AM »
Anyone ever compare the ride height between the two?  Also how is the handling affected between the two?

Thinking about replacing the Eibachs on the rear of my GN to get a little more clearance above the 28" tire when I have a passenger while going down a bumpy road

A lot of broken parts does not make you a racer; it makes you a slow learner.

I took my Eibachs off after I redid the rear suspension my 28s where sitting awful close went with the Moog Cargo coils variable weight. As long as there is a good bar on the back car will be fine. I stayed Variable weight since the Eibachs were a variable weight spring too. just wanted to pick the car up a couple of inches. Took the Eibach off the front when I redid the front supension too.

Yeah, the Eibachs are variable and they seemed to work fine.   If one is trying to be technical, most shocks are valved for a linear spring rate and the variable springs also tend to unload the suspension more abruptly than does a linear wound spring after launch.

In the back of my head, I keep thinking the springs on the other car are variable rate but I might be wrong.  It has no problem with the tires even with someone in the back seat.  At any rate, spring or not, I sent $42 for a pair of standard replacements to the Rock.

Eibachs still on the front at this point.  For sure they resist weight transfer

I use standard springs from a Celebrity wagon... I've seen springs from a Fox body Mustang used as well.
