Sorry I can't give you direct feedback on the Quick Times. But I will say that they where made for drag racing while the GY are not so I would imagine that the two sets, if the engineers did their job right, would back to back be very, very different. I do not recommend drag tires of any kind for road courses and the like. I know some folks run them and like them but I still can not recommend them.

Why the Quick Times? Want some thing sticky that can be driven in the rain? If so, the GY and maybe the Avons. But Avons are pricey. Are you concerned about price and not rain? You could try Hoosier TDs (DOT). Sure they are bias but they can be a ball to toss around and don't require a bunch of static camber. Forget any amount of moisture past morning dew though! They also have a DOT race radial but they are very short in 15". Just need track tires? Go to a vintage event and fill the trailer with free slicks? Want something in between but don't care about cost? Grooved slicks like an intermediate tire.

If a tire like the GY BB is what you are looking for, look no further.
