Tips & Hints
Spin each wheel on a polished axle with graphite and count the number of revolutions. If a wheel wobbles, try spinning it again. If it still wobbles, get another wheel that does not wobble.
Tungsten Putty is ideal for getting your car up to the maximum 5 oz limit. Drill a hole in the bottom of your car and insert Pinewood Pro Putty as the last step to bring your car to 5.0 oz. If the official scale weighs you in at 5.1 oz, simply remove a small amount of putty to bring it back to 5.0 oz.
If your block is cracked, don't panic! The only problem with a cracked block is if the crack is near the axle, which can cause the axle to move. Random cracks in safe areas can simply be filled with wood filler.
