drums worth it? what do i need

It matters more than speed. Modern cars stop in such a short distance now compared to way back when , that it is much safer to have a quicker stopping car at any speed. If the car in front of you can stop in x amount of feet at 60 mph and your car will only come to a stop in 2x feet at 60 mph. You can see the advantage of better working brakes even if your car is not modified to go any faster. It is much safer to have better stopping rear brakes than over functioning front brakes. If the rear lock up first, you go straight. If the front lock up first, you go in donuts as the rear comes around to the front. Think trailer brakes on an 18 wheeler. To keep from jackknifing they apply more rear brake.
