hi, guy's, Thanks for the help. I looked up the pads and they are wagner thermoquiet ceramic #pd161. They do not get any better with heat. Tires are 225-50-16 continental extreme contact sport. Also Old booster was set up with proper gap and new 7/8 master cylinder . additional information- Was a standard transmission but was changed to 4l60e automatic and a LS motor. I changed to a 240z automatic peddle. I'm thinking about trying a new 8.5 inch booster.
