With 100lbs/inch springs on the front is there a need for helper springs?

thought this may be of some interest to the resident super drivers/racers

just happend to find it while pondering my suspension & brakes in my sleep haha

I know this is an old thread, but I have some fairly good info to add to the last post ^^. I talked back and forth with the guy from K-Mac to get a clarification about what strut type their adjustable caster/camber plates work with. They DID NOT understand, in the Super Beetle world, we differentiate by the strut type. To us, 3 bolt is the early suspension and 2 bolt is the later suspension. They, on the other hand, could not care less how the struts attach on the bottom end. To K-Mac, ALL Super Beetles are 3 bolt, because they require 3 bolts to attach the upper strut bearing to the car (as opposed to, for example, the 4 bolt strut bearings used on Porsche 944s). Therefore, their adjustable upper strut bearing (caster/camber plates) will work on all Super Beetle suspensions.

Having been made aware, they guy told me this will be corrected upon their next update of their web site.

yeah that is because the bolts down there are as irrelevant as, for instance, the wheel stud pattern. The K-Mac stuff fits all Supers aka strut-equipped Beetles
