    On alignment table the wheels migrate out going both forwards and backwards.

    However, going backwards the wheels migrate out sooner, and farther, than when going forwards.

    It seems to me that this indicates the axles are slightly toe in going forward and toe out going backwards.

    Assuming for a moment that you cannot change the drill angle, and if I am correct about the alignment issue at hand, and you must either have the slightly toe in condition or turn the block around and drill so that the block has a slightly toe out condition. which would you choose?

    Since the wheels do migrate out in both directions, does it really matter? This is a basement scout car build, without precision tools. Just grandpa and the kids trying to win a race.

    Toe in is better than toe out. How much bend is in your front axle?

    I haven't done the front axle yet. I am drilling the blocks and checking the drills. I plan to try and achieve about 6 degrees in the front axle bend.

    How high did you drill the front axle over the rear?

    I haven't actually measured it. I use the "high" hole in the Silver Bullet Extreme Jig.
    Edit: I mean to say that I use the front bushing for the DFW and the High hole on the other side, and never checked for a difference in height of the DFW

    Wheels can give you false readings.

    No. I have been using wheels that are not bore polished (Black Ice Ordered, hurry and send it LOL) and have been turned but are in the Grade B pile.

    Do a very quick prep on them. You are shipped!

    I will do that and use the best wheels for the test. Thanks for the help.
