I have an 08 Mazdaspeed3. I have a couple mods to it, Cobb accessport, Cobb Intake, Cobb Downpipe, and Exhuast. I went to the dragstrip and was running high 14's..with MPH in the low 100's..maybe I just can't drive, or my street tires are kinda worn...but before these mods I was running same times just this time faster MPH. So my questions is if I were to get some Drag radials, what SIZE, BRAND, and type of radial should I buy....??
