Well.... I was told I needed to make a solo sound pass. I also got dinged for no helmet so I went home. I think you will be happy with the Super Turbos, they have a nice sound.
Funny thing.... It was the first time running the E70-14s at the track. I made several passes in the 14s with a high of a 14.7, then ripped off a 13.2 once I started to figured out how to launch.
