The GQ tires were made with the purple spec stripe at the last years snowbirds. I had the first set on display. When they first came out they did not have the stripe. They are legal in any spec WGT tire competition. As far as I know Jaco does not have any purple stripe and not legal in most WGT/spec tires races(because they don't have the stripe). They will be bidding for the Snowbirds this year. They also sent a bid on the ROAR National held this year.However it was given to BSR.
