Removing ABS on FD
if anyone has experience with removing ABS from their FD, i have a couple questions:
1. does simply removing the ABS fuse simulate no ABS accurately? does the ABS hydraulic unit do any proportioning or other magic? will it simply be a passive conduit if unplugged?
2. if replumbing without the ABS, did u retain the factory proportioning valve? i would likely add a cockpit mounted bias valve but this is different than the stock proportioning valve. it is an interesting device in that it retains a linear relationship up to a certain pressure, but then decreases rear brake pressure a fixed percentage above a define mastercylinder pressure. the pressures are in the manual, but it's hard to extrapolate what 4000 kPaf is exactly (is it 50% brake application, 75% etc)?
the reason i ask these questions is that i'd like to remove the ABS from my track only car. the ABS unit failed at the track last weekend and i'm weighing the options (replace, remove, etc)
thanks
