Found these OK for the road, did le mans on them in the rain from Cambridgeshire but standing water was the big issue with them
I had a set of OZ Ultraleggeras on the Z4 (3.0) for track use. As mentioned, with standing water they are shocking. Saying that though, everyone I have spoken to has said that the Avons aren't great in those conditions. I suspect that is down to the lack of weight.
Any track biased tyre would probably work well on the Aero due to low weight
