Anyone on here running slicks in competition?. Fitted new Avon Slicks, a15 compound, last week and did six runs up Castle hill climb. I now find the inside three inches have grained up badly. Was running with two degrees of neg camber, but now reduced this to one. Will try this next at Wiscombe. I think this must be caused under hard acceleration as Castle is a steep climb with only two real bends. This is only on the front tyres which I run straight. Under full power in first and second gear would the straight front wheels switch to toe in or out pulling hard on all the bushes,etc?. Den.
