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.
