Well I finally upgraded to the 12" brakes and B spindles 2 week's ago. Today I slid right into the rear end end of a Camry. When applied hard the front brakes lock up and skid. I guess i need those 7" rims and 225/50/15 tires and rear disks with adjustable proportionig valve. I have been verey happy with the brakes till now. I have 205/60/15 front tires on 4.5" rims now. Just not enough tire up front. The rear drums did not lock up or skid at all and they are 1 week old. I feel i need more rear brake and front tire to balamce out the system with an adjustable proportionig valve to balance front and rear. Here are some pics.
