Suspension Modification

[Howard Wright]

I believe the mod above turns the spring into some kind of panhard rod ?

an alternate option is to increase castor angle by dropping the ball-joint swivel down by an inch or two ??

Hi Flywheel 

Yes I think the spring does act like a panhard rod.  

Increasing castor may help handing if the the existing castor is insufficient but on a standard Ruby with a well put together axle the castor should be enough. Simply dropping the radius arm ball join without also fitting a wedge under the spring support will put the spring under torsional stress.

Locating one end of the axle, either by pinning the shackle or fixing the damper arm to the axle stops the axle from moving from side to side. It’s a worthwhile modification that doesn’t alter the basic suspension geometry on an original car.

Cheers
