Wilwood Brakes Update

Well I finally drove my car with the Wilwwod front disc setup, awesome! I am very happy with them. I ordered a variable proportioning valve but have not installed it yet. I went from four wheel drum to front disc. I have tried numerous high speed panic stops and the car seems to stop fine. No out of control skids, so I am not sure if I will use the valve now or wait till I do the rear brakes too.
