APPENDIX 5 – TRANSPONDERS - APPENDIX 5 – TRANSPONDERS
APPENDIX 5 – TRANSPONDERS To compete, you need an AMB 260X or AMB/MyLaps X2/MyLaps TR2 transponder. You can bring your own or rent one from ChampCar. Rental transponders must have a factory MyLaps / AMB transponder mounting bracket affixed to their car in an approved location. ChampCar sells mounts at tech inspection. No loose, zip-tied, or duct-taped transponders are allowed. If a rental transponder is lost or broken, you agree to be charged for its replacement. If the case is cracked or deformed in any way, but the unit still works, you agree to be charged for repair and testing. Transponder Mounting Tips: Always mount the transponder so that the black (AMB260X) or red (MyLaps TR2) is to the ground (not sideways). You need to get a bracket (they’re only $10 and hold a $500+ unit in place). Do not mount it near the exhaust, as the unit will melt. Put it in a safe place where it will not...

4.6 - PLATFORM SWAP
4.6. PLATFORM SWAP 4.6.1. As an alternative to an engine swap, teams may qualify for a platform swap. A platform swap is defined as replacing the original components with all the components from the same chassis family (i.e. – 318 to 325 BMW engine swaps or 2.8L to 5.7L Chevy Camaro). To qualify as a platform swap, all of the differing vehicle components must be swapped to match the new platform. This includes engine, transmission, differential, suspension, fuel tank, etc. The VPI of the car will now be based on the car and engine combination as presented to tech, regardless of what engine may have been installed originally. No swap surcharges shall be applied to platform swaps.
