get off it guys! KISS! (keep it simple stupid) ABS doesn't belong in IT. It is simple and sensible to remove. Every ABS master cylinder has 2 circuits that control the brakes in normal fashion should a sensor(s) fail. Standard, simple, sensible race prep is to split system front to rear with a bias valve in the rear circuit, which is plumbing 101-if you can install aeroquipt brake hoses, you can certainly deal with ABS removal, If you can't, maybe you should consider a spec racer.
If it ain't broke, don't fix it. Phil
