The term IROC is the acronym for International Race of Champions. The concept of the IROC series was to identically prepare stock cars by a single team of mechanics in an effort to make the race purely a test of driver ability. If you would like to know more about IROC there are many articles on the webbernet. Anyway, this article is about building a set of IROC hot rods or as I refer to them IRODs.

One other note on this build. All the cars will be very close in specifications how ever they will not be exactly alike. There will be slight variations in magnet strength, and armature ohms, however, they will be very close but not exactly the same. That said, it shouldn't matter that much due to the fact that each driver will drive all 4 cars during the race.
The 4 Dash chassis are the version 2 chassis that has the 16 ohm 2 lam armatures. The first thing I will do is to take them apart so I can tweak them as I rebuild them.
I have used this method on some fray cars and have had hundreds of laps without an issue. It involves a toothpick and some super glue. Take a toothpick and put some super glue on it then put one drop on the winding of the armature pole. Using the side of the toothpick gently spread the super glue over the armature pole winding. You will notice the super glue will wick into the winding. If there is any extra glue then take a paper towel and soak up the excess by lightly touching a corner of the paper towel to the excess glue. Now repeat this process on the other two poles of the armature
