Hi guys i am replacing my rear beam, a complete rebuild with new parts throughout and polybushed.powder coated. i have an old style rear beam with the brake bias valve, to fit on my 1998 golf the questions are. Is it worth keeping the bias valve system? and why did VW remove it in later models? I recommend corroless 2 pack for protecting the hinges we use it on subsea rov's and after 10 years under the sea this stuff is still on. thanks
