Driver Notes:
G-Comp kits will test your drive train! Your power will be hooked to the ground, so be prepared!
- Depending on how and where you drive, your car can create huge G forces. You may need to Dry Sump your engine so it won’t starve for oil.
- An oil pressure light is a MUST, as our expert drivers can attest, time is limited during competition to watch the gauges.
- At least one day professional driving class is recommended for cars equipped with engines exceeding 500HP.
This does not work with BBC engines without modification
