I think with the aluminum drum, you need to run the red lined band?

I used the steel drum as I planned to do more street driving, but I doubt I have put more than 3,000 Street miles on the car.

I used the Billet accumulator with the dual ring seals and built in blocker rod. Not needed, but I don't think it was very expensive? Rear Billet Servo with dual seals was a bear to install, needed several shims to get the seals past the retainer lock groove. It is likely overkill, but I liked the idea that it would be almost impossible for it to get cocked in the bore.
Front servo setup is the Sonnax super hold servo kit 22301B-01K.

The MaxLug pump gears are overkill too for my setup.
