Thanks guys, good info. I still don't understand the front measurement though. Doesn't seem to relate to anything on my 996 SPS. I've got 3 rings showing on the inside (Ohlins) which is 197mm from lower tripple to bottom of fork seal. I have the rear tool and that all makes sense although I have been measuring from the outside of the nut and not the centre of it which is a difference of 20.5mm. So from centre my rear ride height is a whopping 264.5mm but doing it the Section 8 way I have close to the 604mm they talk about. My rear linkage is also longer than my manual says is max. Sooooooo not sure where to go from here. My bike is very twitchy coming out of corners. May be I'll make the rear linkage the right length and see what happens but it is going to lower the back a lot.
Sticky backed plastic and empty washing up bottles ? Eat your heart out Blue Peter ! Take a sheet of plywood that has been kicking around the garage for a while, 2 ghastly yellow anodised Pro Bolt frame bungs retrieved from the scrap bin and slightly modified, some nuts and bolts, a few basic tools and a drawing supplied by Cranker V2 and this is what you get. It fits perfectly, it's definitely paralell to the ground and is actually quite robust. Took a quick measurement and I reckon my rear ride height is about 7 or 8mm low on the 245mm base figure in the WS manual. As I'm putting the Metzler Racetech K3s back on for Tuesday it will be an ideal time to adjust the set up to be slightly more aggressive. Andy
