Really disappointing. It gives great traction and feedback for a few laps and then it literally dies and becomes an average road tyre. Balance went all over the place with intense understeer, vibration, and average braking. It picks up a lot of debris which seems to affect it more than similar tyres. Not recommended.

swapped my ps4 out with these, although the tires have more feedback and are a bit grippier on dry surfaces. they lost a lot compared to the michelins in the wet. The only reason i ended up with the Conti's is that the wait for michelins is roughly 2 months in Norway as of April, and I needed tires now. plus my size is quite wide so not a lot to choose between for a 2,3 tonne estate. When this set wears out I will be trying out the sport contact 7's if they come in my size.
