Anyone using z32 calipers? I am trying to figure out which lines to buy for my 510 with z32 calipers front & rear. Will the z32 lines work or maybe the 240 conversion lines?

what kind of lines are you looking for?

the braided stainless I assume.

I'm not honestly sure what kind of fittings the 510 uses to the metal line, but probably different than the Z32.

if you're not terribly worried about DOT cert, you might wanna check out a hydraulic hose shop and have them fab up a set for you, make sure to take examples of the fittings you'll need on the hoses and let them know it's intended to be a brakeline.
