I run them as my general driving around tyres and my go to wet track wheels. I wouldn't use them as an only set as they're really soft. but I challenge a lot of cars to keep up with me in the clio in the wet on the rainsports, they only tyre that's better would be a proper cut racing slick but not at a few hundred quid a corner.
@Pav can testify what the rainsports were like at oulton last year when we was out on track together. One advantage is it's got 2 sets of wheels so can run the RSR's when the tracks dry and hopefully soon some full slicks.
