Brake upgrade danger.
 

Based on an artical at z car homepage I went out and got a set of calipers and rotors from a zx turbo car at the junkyard. They say to drill out the threads in the spindle ears and bolt through into the calipers and use a washer in between to space them out to align the calipers over the rotors. This is dangerous because the spindle is made from a forging. This rough surface is neither parallel nor perpindicular to the rotor faces! If you bolt this on, the brakes won't seat properly or even effectively stop the car. The proper way to do it is to remove the spindles and have them drillied out and faced in a milling machine. I'm going to wait until I do the suspension since I will have to take the whole thing apart. DANG!
