Two more cents. Don't know the exact spects of the brakes, but, I do know what works. Couple of years back I upgraded the front brakes to lthe Wilwoods and the old girl stoped much better and with another addition of new front shocks a month later the nose dive that the brakes caused went away. The other day some clown did a panic stop for a squrell in front of me and as I was following two close a disaster was close. The brakes did their job and I stopped straight and true. No muss or fuss, just good brakes and bit of luck. Quit over thinking the job and get on with it, it only takes a days work with cleaning and painting and simple tools. Unless you're doing some heavy racing the four pot Wilwoods will get the job done. Only other tip is "don't follow to close"
Cheers Don
