Yes they offer good straightline poerformance, but I would never use them for road racing. The sidewall will flex too much in the twisties. For road racing, I suggest you go with the 555RIIs. They were designed for road racing (very strong sidewall). Both tires need to be warmed up to hook well, tread pattern is the same, the sidewall structure is what makes them different.
