50/50 or 60/40 front to rear?

does it depend on the weight distribution?

depends on the weight distribution.
if your car(don't know what kinda car you got) is a 4th gen f-body the weight distribution is like 58-42, so if you set it @50/50 you're rear brakes are going to lock all the time.

it's also dependent on what brakes you got...I'm assuming you got aftermarket brakes due to you actually having a proportioning valve so that needs to be taken into consideration as well.

To my knowledge, there is no set standard formula for this that is easy to comprehend. It's not 50/50 either. It depends on weight distribution, tire size/compound, brake compound, overall braking torque output to each caliper, etc.

When we set up cars we start at a 90/10 or 80/20 bias and turn it up until there is lockup. The factory rears are hypersensitive and actually quite effective. At a lower bias it typically feels like the *** end wants to come around the front because it's trying to travel at a higher speed than the front - giving the car a loose feeling under braking. You'll need to really get some seat time and testing to dial it in and feel poised.

Seat time and no it won't be 50/50 as already stated.
