Some asked about the brakes I am using. The stock disk brakes are fine for me now. I do not road race this car. The brakes stop the car with no problems. I have a new booster, master cylinder, rebuilt calibers and wheel cylinders. New brake lines , shoes and pads.
If you jump on the brakes it will throw you through the windshield!
Road racing , I would consider replacing rear drums with disc brakes. Brake pressure ratio valve to adjust brake balance.
