I recently installed an Ironman suspension kit (4 coils, 2 gas shock struts and 2 gas shocks) on my Gen 3 DiD and subsequently carried out a quick flex test along the lines described earlier in this thread (I did not do a full test including wheel travel graphs as before, because temperatures in the garage are starting to get uncomfortably high this time of year <img src="/forums/images/graemlins/wink.gif" alt="" /> ).

It seems as though the stiffer springs reduce the flex by an average of 8.5%. This was as expected: the lift is achieved through a higher spring rate, while a reduced spring rate is beneficial to flex.

Still, if the front anti-roll bar is disconnected, the flex is significantly better than standard. <img src="/forums/images/graemlins/kewl.gif" alt="" />

By the way, the lift with the Ironman kit is of the order of 40mm (around 1.6").

The next step will be getting some decent tyres to replace the Super-Slip-Non-Grips currently installed <img src="/forums/images/graemlins/pfft.gif" alt="" /> .
