Had the ADO8 on my kit car, good tyre with low wear rate. Used on track and road and where good. HAve the A048 on my BMW track car and their excellent, only really use them for a intermitate tyre but been good.

If you have a spare set of wheels it would be an idea to get the AD08 as an every day tyre and then Slicks as your track tyres. Can use the ADO8 if it rains and slicks when its dry. Slicks give you so much grip and are cheaper if you buy slightly used. On an RS would be brilliant.
