It seems the RA1 has been around since before time began. Ask an "old timer" (well, relatively) and they'll tell you that the RA1 was the holy grail of DOT competition tires. A decade ago, a walk through the hot pits of any track event would net you rows and rows of RA1-shod cars. Times have changed, but have they passed the RA1 by? We installed a set on Project G20 Racecar to find out.
