Re: rear coupe brakes

The spindles off the GTI have the mounting holes for the caliper and 
it is a simple bolt on.  Not big surprise considering the drum system 
was essentially taken from a Rabbit..  The only difference between 
Audi 90 and GTI is that the spindles have different number of 
mounting points.  Also the GTI rotor contains the bearing inside of 
it while the 90 has a seperate rotor and bearing hub.
The adjustment of the brake proportioning was done by trial and 
error.  I was kind of scared to take it to any speeds that would tell 
me if the front or rear locked first.  To my surprise it needed only 
minor adjustment.
