Lots of people go for custom linkages etc, this made life much easier for me!

Rebuilding services are widely available also

If you want yours reconditioned theres a place in Brum called Revs, got a good pedigree and reasonably priced.

Best option is probably the GF kit. Reconditioned CBR600 shock, new ohlins spring, new custom lower dogbone. Increases rear ride height, improves handling dramatically. Race proven.

and how much am i talking for one of those ?

It's around £240 but worth every penny.

You can buy the lower dogbone on its own which I think is around £80, second hand CBR600 shock would be around £50, sending it off for a refurb would be around £100 (probably plus p&p) so you're already on £230 without the new spring. The kit from Graeme is a good deal.
