ray-good suggestion-remove everything! get the weight off the left front of the car for better ballance. replumb underhood with the stock master cylinder, and be sure to remove the rear porportioning valve located on the firewall next to the left front fendeder. then add a bias valve on the transmission tunnel next to the gear lever so it can be adjusted on the track.(obviously you will have to run the rear brake line through the passenger compartment, and out on the seat support, close to the "T" for the rear brakes) that is what i have done, and it works very well. good racing, chuck
