Hawk brake pads - worth it?

The factory brake system wasnt designed to be able to powerbrake the car or hold the car at a launch. Although if you have a line lock it should hold them
That being said you might not have enough pushing force apllied to hold the front.
Are you running power assist brakes or manual brakes?
Also why are you holding it at such a low rpm? A good launch rpm should be up in at least the 2k - 3k range. Plus are you describing when you go to launch or are trying to powerbrake the car and do a burnout?
