Nice thread!

*If you have a locking lug nut with no key, mask the wheel and weld an "inexpensive" socket extension on it usining your mig. Just a few spot welds so that after you remove it with your ratchet, you can cut them off with you cutoff wheel and go to the next wheel.
*If your headers are dragging in and out of your driveway entrance, throw a 6' piece of 2x10 at the low point to help you get in and out.
*If you are having cooling problems, switch to synthetic oil until you get them figured out. I have overheated regular oil and the bearings looked like flaky pastry crusts! Conversely, I locked my 225/6(with Mobil 1) up a couple of times so it shut off. Let it cool down and no disaster.
*Always carry a spare ballast resistor!
*If your car is running hot, turn on the heater full blast. It helps the cooling system just a little more to help you get it off the road.
