I recently made my first dive into the 11s. I hit an 11.92, then backed it up with an 11.7! To do this, lol, I was launching at over 5500 RPMs. Man, if these traction bars can keep this kind of force in check, they are a phenom! Gret product you have here guys. Looking forward to the upgrade for them though. (even though its chafing my IC pipe) I am going to be keeping these, why swap out a good thing when its workin eh!
