Hi, my '59 Brera came with factory-fitted Bridgestones, and after scrubbing off the fronts in 9k miles (another story about bad factory-set geometry) I was going to fit PZero Nero's. I have been a 'Pirelli man' for several years, however when reading reviews on PZ's, and trying as hard as possible to get a balance view, I opted for ContiSportContact 3's. At the same time I had my Brera's geometry sorted by Peter Cambridge and the Bridgestones are coming off this week after doing a further 20k miles on the front! The CS3s don't appear to have that much life left after 20k on the rear, but I do like to push the car in the corners
You're right in that the Bridgestones have very little rim protector and the CS3's have a much bigger one, although I still managed to ding one of my rims on a nasty corner :-(
I've just bought two new ContiSport5's from Camskill Performance this week - cheapest by miles! £30 to get both fitted by a local tyre fitter. Also the Conti's appear slightly wider than the Bridgestones and the new CS5 shares the 'Black Chilli' rubber compound with the ultra-high performance ContiSport 5P, so am really looking forward to getting them fitted.
As you mention, Breras are notoriously heavy and have some bad handling habits, such as tramlining and becoming alarmingly unsettled if you hit a bump at speed or in a corner (confirmed by Peter Cambridge). That said, I absolutely adore mine and wouldn't swap it for anything less than a 8C/4C
P.S. The Accellera tyres you have fitted are known as 'ditch finders' and you definitely need to stay at home in the wet!
