Thanks for the input E55EX RACER, much appreciated.
I've not changed any of the suspension components,, other than two new springs on the front. I did hit a very large pot hole on the passanger side towards the end of last year, and that knackered the front and rear passanger side wheels....hence why I'm running on the 18" ST220 alloys, as they were the cheapest and quickest way to get me back on the road at the time.
