in my experience, radials have been about a tenth faster. i see no differance in consistency. the only drawbacks in my opinion are tire life being shorter with radials and your engine will work harder by running at higher rpm due to the fact that radials dont grow and genarally are smaller in size. the best way to go is run bias ply but have radials for heads up runs, keeping in mind when you put the radials on , expect to pick up reaction time. imho
