Thanks for the input everyone, I really didn't mean to cause such a fuss
During the past 6 months of trying to rectify this I was amazed by one thing, both Chris at Inline and Capital S + S told me that the brand of tyre can make a huge difference. When I had this proved to me and I changed all tyres from Pirelli to Yokohama it was an amazing difference, like a different car. So with the trye change I came from a huge problem to a minimal one, I think from here it's in the 'fine tuning' as Mik suggested.
So like the lady she is I'll continue to fiddle with her, treat her kindly, service her regularly and give her a good hard drive every now and again, and life will be good.
Thanks to one and all ...
