Although not the answer you’re looking for, a mate of mine put some on his S2 when he couldn’t get hold of 52’s. He noted that while comparable in the dry, the 52’s were much better in the wet.
He’s not had them long but I can ask him if they are better in terms of longevity.
I did chat with the lad from Seriously Lotus at Croft though and he reckons they last a fair bit longer.
(Edit- my mate said he’ll be along shortly to answer for himself )
Yes, I’ve been running them on the rear for a few hundred miles plus 1 track day.
They seem to be wearing well, too soon to say though.
Dry grip is impressive but the wet grip is nowhere near the A052’s, which wore out very quickly, but I’ll be going back to them next time.
Ah. I thought some weren’t E marked. On the Nankang UK website some sizes are described as motorsport only so there is some question of road legality, no?
