[ERA Chas]

Like Ernie did, ask yourself "do I really need a (an expensive) brake upgrade?" If yours are not working correctly, repair them. If they are and you plan track work then go ahead. Or if you want to enhance resale value.

ERA has the rotors, hats and spindles you'd need. You may need Tilton masters and ERA has those too. None of this is cheap however.

Yes, you adjust brake bias and yes vented rotors for the rear as Jim has are effective with the 12.19" fronts.

No matter what you do, lose the DOT5 and get DOT3 Castrol LMA in there.
