Default Removing ABS Unit

So my ABS pump has failed and i mostly just use the Z for track/drift events now so contemplating removing the ABS completely. If this route is cheaper than replacing the ABS pump then I may consider doing it. My question is what is required in order to remove the abs unit?

Was told so far would need custom lines and a new master cylinder, that doesnt sound that bad but wanted to make sure there wasnt anything else, thanks

looking at about $1000 to replace the pump including parts and labor.

Although I don't know the specifics regarding the 350Z brake bias, generally removing ABS from a car already equipped will result in a large front brake bias. Mechanically most ABS systems are designed with a big front bias to keep drivers out of trouble if the ABS system fails.

Install a manual brake bias controller while you are at it. If you're doing track events it'd be worth it anyways.

Sorry, that probably won't do it. Again, its a guess on my part regarding the 350Z, but on other race cars I've worked on where the ABS system as removed (Acura NSX, BMW M3, Porsche 944T) there is an inherent mechanical/hydraulic bias toward the front. Playing with pressure to the rear brakes won't help much.

Swapping to a dual MC setup with an balance bar or properly sizing the caliper pistons, MC pistons, brake pedal ratio, and rotor diameter for a non-ABS setup are the two best options.

Same thing happened to my z abs unit since i only trailer my z to track events i figured i dont need abs so i just pulled the abs fuse out and left the unit the way it is. the only down fall is i lost the speedometer. Its hard getting use to in the begining with no abs.
