Never tried corsa's but had BT010's and they were fantastic, changed them to 012's and then changed back to 010's The 012 rear was great but the front felt a bit odd, it also seemed far more rounded and felt like it wanted to tuck all the time. I do believe the new 014's are much much better again.
1600 miles later and the rear is on it's way out. Not bad mileage for some of you I know but with my soft and gentle touch I normally get double that mileage from 010's
