I have seen these advertised as tarmac/rally/sprint/hill climb tyres. A fella in a clio cup had a set on when I was down at Brands a few weeks back, in 175/60/16 fitment I think ( weird size to put on a Clio I thought ). He said they were ok , however his mate was running " shinyu's ", or something like that and they were both driving rather conservatively ( thats being kind incase they frequent this site ), so I wouldnt trust his recommendation.
