unless your going to drive the road courses there isn't much concern to drum brakes. it will be difficult to depress the pedal with manual brakes compared to what your used to. if you want to maintain the same feeling as your daily driver i would go with power assist! the upgrade will offer the biggest improvement to your system overall! also i have talked to people with drums and people with disc brakes for comparison as i have a drum brake car as well. i have also driven a manual brake vehicle and i would go power assist! drum brakes work just as well in most cases for general driving compared to disc brakes. like the prior posts say, unless your racing it shouldn't be necessary.
