Well it appears one thing everyone agrees upon is that spring rate is the first order of business followed by preload, and finally damping (the hard part). Hope the sprung unsprung weight is a fly in the ointment. I have been living w it since 2001 when I took delivery of a 996 w springs that appear to me to be for about a 200lb load. I figure I was 165+~15=180. At some point I put mags on the bike but never thought much of it's handling. Seemed stiff. Wobbled. May have been damping and or spring rate. I have got it working pretty well now but only by chance it seems, hitting on a good combination of adjustments. I can look back at my record and see the way it was delivered and all subsequent adlustments including doug polen's recommends were not as now. The new Pirelli corsa IIIs seem to want more pressure than stock. Rear spring rate -21/75 7.5 Nm I believe and I measured the frt springs to be about 1kg/mm I think. I calculated that the springs were about 10 % too stiff for me, excepting any argument about weight ratios. based on general consensus. Thanks for all the input,, did not know of the swing arm dimension diff. I am going to do some dynamic testing now I believe. Ciao
