Audi 200 brake MC vs. Audi V8 brake MC...

[Todd Phenneger]

Gerard,
  Putting the larger bore MC from a 91' 200 onto something like
a 5ktq or ur-q does dramatically help with pedal travel.  It
reduces travel and gives a stiffer pedal.  I would consider it a
very worthwhile upgrade when putting larger 4-pot brakes on the
car.  But if you have a long MC like on the 4kq/ur-q/5ktq then
make sure you get the SPACER that goes between the booster and
the MC.  Otherwise the length will not be correct.
  Good Luck
     Todd
