thanks for posting, but a short question from my side: have you driven a Roadster with the Kit before you ordered and think the improved suspension is worth it or is this more about playing around with alternatives of the leaf suspension and hoping for improvements?
no i didn´t test-drive it in advance, but have been in close touch with "the-ones-in-the-knowing"
Besides that the asymetric leaf springs (also from Suplex) that i had fitted previously haven´t just risen to what they were promised to (not the fault of the idea itself, but my very set - which wasn´t ok) - so either replacing the leaf springs or just switch to the solution my car was intended to have from the start (but not available then yet) wasn´t a long guess for me.
After having played around with several set-ups in different cars by now i´m pretty sure that this will be "it" - for me at least.

And, yes, you should at least be "well equipped" workshopwise plus it DOES help if you have an engineering background going with that too.
But then again it isn´t much of a guess how to assemble the puzzle - critical shoul be, as you mentioned, the proper set-up (axle alignement both ways/sides etc ..)
