I haven't had to replace my RA-1s yet but word on the street is that the R-888s don't need to be shaved like the RA-1s. They also have a stiffer sidewall than RA-1s so your effective spring rate will go up. While people generally like them more for track events, some of the racers haven't been as happy with them and everyone is struggling to find the correct tire pressures.
