removing the abs totally is one of the best things you can do to improve the brakes!! the feeling in the pedal is 110% better!
I have removed the abs,have 283mm cossie disks on the front and have also done a rear disk conversion!
I drive my car hard and do quite a few track days every year and i have NEVER had any issues with it trying to swap ends!
I left the rear load compensators on and did not use any form of bias valve!!
