Ive had a pair for near on 2 weeks, and they have been superb, wet or dry,hold the road really well, tonnes of grip even when used on mine with a remap on the ed30, with my latest more aggresive adjusted map from superchips,get very little wheel hop/spin when being a tad over enthusiastic on the go peddle.
I can only comment on comparing these to Bridgestones , Dunlops, and Hankooks, these are Way better then those.
For £85 you are certainly NOT wasting your hard earned imo.
