Mm tried a C spanner that mate uses for his coilovers but it was too big. Guess it needs a fairly specific size.
Perhaps a replacement shock from a Busa or GSXR will be the way to go if with the standard shock I am still going to get a lot of sag and bounce even with preload and rebound set up more appropriately.
Will keep an eye out for a cheap busa or GSXR1100 shock, couple on trademe at the moment but they're up around $200.
Thanks for all the help guys. Still keen on a C spanner if anyone has one or knows where to get it though
