Panic over, 4 tyres arrived with the wrong weight for the fronts which were packaged together. Car booked in tomorrow and then I'm not in the country to drive it for a week
To be fair, I had to drive 60 miles in the rain yesterday and the cups did surprisingly well, particularly in braking performance. Traction was not so good and lateral grip was fairly fun but I wouldn't be so worried in future if I got caught out.
I believe the cups have more grip than normal tyres in the wet when up to temp (as reported by a certain W Rohl). It's just standing water they don't like. My mrs some how knows about this, which, means my left ear hurts when it rains
