I honestly can't speak on this one as the braking on the Syncro is quite different.
I know some people have struggled to lower the rear bias enough. Ask on CGTI - more track numpties on there.
cheers fella i had it on the brake machine yesterday while i had tracking done front were reading 250 ft/lb rears were 100 ft/lb but didnt even attempt to lock up on the rollers so hoping there be fine

fitted fronts drivers side seat put seat rail in front and flat bar for rear may not be ideal but really cant see it goin any where in a hurry
rear strut brace fitted/welded in
just need to wire the mfa stalks up now cant seem to get them working for some strange reason
