Well... as Carsten pointed out to me... the Spax kit is Tüv approved. And they usually dont lend their name to something that is going to fall apart
?
- are you saying TüV has approved that kit for fitting onto a Murena in the described way ? - without any mention of extra chassis support ? or just the kit itself ?
I am not sure I understand your objective - If all you want is a lower nose, then why don't you just adjust it down ? - thats the beauty of the torsionbar arrangement.
With regard to the strength of the chassis, even with L-brackets and diagonal support, the chassis was never constructed to take much load there - and remember handling has a lot to do with chassis stiffness (well, on a gocart you actually use the flexing of the frame as suspension, but thats another story). The torsion bars cleverly move all the weight-force into the centre pan of the chassis, where it is strongest, and only the shock-absorber affects the chassis directly.
Admittedly an absorber gives a fair load - and I believe a Murena would handle better with a strut-brace fitted, - but it is in my view counter-productive to also move the full force of the weight onto that same (over)loaded spot.
Play around with absorber settings, or even antirollbar if you want to explore the possibilities with the front suspension, but I would leave the springs alone where they are.
So you see, - I didn't mention the risk of you killing ENTIRE class of school children on their birthday (nice one though, Krede) :-)
