With regard to not having a hoop or leaf springs, yes I understand that Rogers assisters won't work as designed, however, I didn't know if with some modifications and using other parts of the rear axle/body set up they might work. I already have the SSL rear spring setup with the double springs which generally work well, but not with two up and a case on the back. They also seem a little short as I have them wound up to the top to give as much movement as possible. Maybe another inch or two would work better, (as the Bishop said to the actress), which is why I wondered if Rogers assisters would work as better bump stops than the chassis does, but with a slightly different type of fitment than the current design?

As. a matter of interest, does anyone know the spring rates of the two springs supplied by SSL?

Sorry don't know the rates Paul, but Dan at SSL would be able to tell you.

My thought's given the explanation above which came straight from Dan, are that too much pre-load would bring the lower spring closer to being coil bound so you would have less travel from static before the higher rate kicked in, defeating their object to some degree.

The prototype pair on my Roadster have the pre-load shown in image above as pre-set by Dan. Whilst I have played with damping I'm satisfied with pre-load as is, even two up, full tank and with humungous case on the back courtesy of swmbo
