Save yourself all the questions and headaches of alignment. Buy the BLOCK from Jewkes Engineering. Do not fight success. Negative camber on the rears. Positive camber on the front dominant wheel. Non dominant front wheel raised. Steer your front dominant wheel into the rail to make a rail runner. This may go against common sense or science. Buy the BLOCK. Jewkes axles and wheels will insure your boy will blow everyone away. Don't deny him that feeling. PS - get your center of mass back further closer to 5/8.

Hello, My son has consistently done extremely well the past few years at the pack and district levels. (2008, 3rd in district, 2009 2nd in district). Our alignment technique in the past always involved negative cant on the 3 touching wheels and other details such as tapered axle heads, 1 to 1 1/4 com, low weight and straight alignment. (may try a Rail Runr this year) The question I hope the experts can help me with is how much cant is too much. Generally, we try to negative cant enough so that only the bottom edge of wheel (closest to the car body) consistently touches the track surface. We check this visually on a flat surface. Sometimes we apply a bit more or less if needed for straight alignment. Not sure what degree of cant this is but it does seem to reduce friction and produce a fast car. Please let me know your thoughts? Thanks! As long as your rules allow then 2.5 degrees on the back is perfect. If you railrun (ride the rail). Then postive camber on the dominant front wheel (DFW) just like ACME mentions. The Block is key to sucess. For sure get a copy of it.
