I have the 84.5 25th Anny car, And would like to upgrade my brakes on it, but keep the stock configuration.
Its got the bigger brake rotors in the front.
Drums in the rear.
Looking at upgrading the Brake booster as I think mine is pretty much dead.
Master cylinders.
And new rotors because mine in the front need to be replaced (small crack)
new calipers and pads

 

cool im looking for the same thing. although mine is not the anniversary edition. hopefully with both of us someone will help us out
