For the sake of discusion though, the hose I will be using is 0.15 lb/ft and fluid weight per foot in the tube is 0.042 lb/ft. 20 ft of tube would add 3.8 pounds where the stock line are 2.25 lb without fluid. Doing some quick estimate-math, let's say the line is split F/R on the new line, new pump is 100% rear and OEM stuff is 100% front. Net results, it adds 6 pounds overall (definitely not the goal) but does produce a 0.4% weight shift to the rear of the car.
Doing the math that way is easier but it misrepresents reality...

At best you are adding 10 lbs to the rear, removing 7.9 lbs from the front and adding 3.8 pounds to the entire length of the car with the lines and fluid... Your set up adds 7 lbs to the car.

As an aside... depending on the path you take to route the lines I think your 20 ft estimate may be shy of what you will actually need.

Anyway... I know you did not create this thread to have this discussion. Good luck with it an post some pics!
