Very cheap but made in Japan so they must be good I thought. First impressions are bad. Ugly compared to previous soft Dunlop Sport that look "cool". Traction very good but cornering grip for the first 400 miles are terrible but fun around UK roundabouts. After 500 miles the tyre is fantastic and well suited to wet UK roads. They seem to be wareing very slowly and I find hard to believe. I suspect there are two types of tyre, one that is soft and grippy the other hard and nasty, while the FK452 must be a rare medium compound ideal for spirited road driving but softer brand names should set faster lap times on the track. Only can compare to the relatively worn P-Zero's that were on before, but so far a thumbs up. Had them on the rears for around 700 miles. A much more progressive break-away in the wet and dry and now able to use WOT in the wet in 2nd with no wheel spin in a straight line. Going to get them on the fronts next. One negative, experienced an cyclical motion on a gentle uphill curve at ~110 leptons. I put it down to overly tall treadblocks moving around as the tyre is new rather than soft sidewalls as it is gradually reducing and now pretty much gone.
