Been there done that, helped a mate build a similar front end a few years back, got a pic somewhere must try and find it and get it put up here.
As for Avon Azaro's I raced on them a couple of years back when racing my Fireblade, I remember finishing 3rd in class on them when you were finishing in the hospital Steve and in the wet at Thruxton that year they were awesome, I was passing several other Streetstock competitors each lap.
