Let's just say I had an "idea" not a design. I didn't actually manufacteur parts or invent anything new; but what I did was use what was on the market.

In 1999 me & H2OSB (John List) together tried to figure out a way to make our own small diameter spring struts mainly because we couldn't justify the cost of the H&R, Koni, or Kerscher kits.

We ended up using parts from the 1303, Porsche 944, & VW Golf and came up with a design that worked well. We had intentions to make and sell them on a limited basis but after thinking about the legal problems and what not we decided not to do so. If it wasn't a suspension componet things may have been different but we didn't want to be liable if a person was in a wreak due to a faulty design. I decided, and H2OSB agreed, that we would give Topline our design so it could have full R&D resources to produce it correctly and a safe product.

So I called up Jon at Topline and explained to him what we had made, emailed him pics, and asked him to try and come up with a low cost product (the others are $750-$1500). After some time I didn't hear from him so I called him back to see what he was thinking.

He explained to me that in order for him to produce a full coil over design that due to the costs of manufacteuring parts the price would be about that same. I replied, "I would do what VW has always done. Use what you have already." I suggested changing the lower spring perch on his adjust-a-struts to a smaller diameter for the springs. This got his attention and for the prototype it was welded but the final production unit has a billet one piece design.

Although these don't have a true full adjustment as the coil-over kits, they adjust via a snap ring at 1/2" intervals, they do the job for half the cost of the big boys.
