Ok, i have searched through the more important (anti rant) threads on this subject and nothing really relates to what I wanna know. So here goes mine...

Running 1.8 ZVH with a few mods to get me the 200bhp mark (maybe - untested as yet), I have standard front brakes and a set of modified Mondeo (2001) rear calipers and discs ready to fit. I dont do track, and to be fair, I dont race around my streets like a boyracer on speed!

So would i need a bias valve fitted, or is there no real point? Admittedly, the conversion is more for looks and ease than anything.

The guy I got the set up off said that he didnt use a bias valve when he had them fitted, but his was a S1 and said that the S2 maybe different.....

Could it just be a case of trial and error?
