I would personally put a hydro in the rear anyway! So many options for it since 370z is such common drift car. Seems to work fine for
cleetus and side benefit you can drift your car around for fun.
Can do it with dual caliper bracket. A bump button on your line lock would be pretty fancy tho. i think too hard to do for it's purpose tho. since you'd need to relieve and then reapply pressure to the front brakes, vs letting off the hydro a little while slipping your clutch.
