There are very few coilovers for the G/Z that are actual coilovers in the rear. Why is that?

As far as true rear coilovers go, is the shock tower and suspension mounts in the rear of adequate strength to support the spring and thus the weight of the car?

Anyone have a set-up as described that can provide insight? What brand are you using?

Thanks.

 

Because the spring is mounted inboard of the hub the amount of movement is limited [geometric position]. The springs probably only move +-1" compared to +-3" on shock and wheel.

So a coilover shock would need to be 3x stronger over a narrower movement range if mounted where the oem springs are or if the shock position was used the springs would need to be 1/3 as stiff as oem............probably clearence problems.

Coil overs have no real advantage over separately located components assumming all are properly designed.

 

That's good to know. I was interested in replacing the spring bucket/arm with an adjustable rod, thus the shock mounted coilover set-up. I wonder if the shock tower and mounting point on the hub are strong enough to take the added stress.

Also, given your comment, that contradicts the high spring rates on true rear coilovers.

Hmmmm. More to think about.

 

Yes, many are confused by publishes spring rates without considering the mounting locations and angles.

All that is important is the effective wheel rate and the road tire interface rate.

The 3X is a rough approximation.............the only way to know exactly is to measure with electronic scales.
