ET-Drag or ET-Street?

I would stay with Et Drags if your class does not require dot's and you don't drive on the street.

drags have a more flexible sidewall and are made of a more aggressive compound. switching to streets your 60' times will fall off.

I've seen mid low 10 second cars go from streets to drags and knock over a tenth out of the 60' once the launch was dialed in. If memory is correct, both cars dropped half a tenth with no changes save for the tire swap.
 
ET drags flat out hook better...but the streets will last ya a little longer, but youre going fast enough to where changing from slick to better slick will get ya better times so i say stick with the drags
