Unfortunately, half a tank in GT500's. Anything less than that and you risk getting temporary fuel starvation on hard launches/shifts due to uncovering the fuel pickup.

It's a bit of a Catch 22. Putting weight over the rear tires can certainly help with traction and weight transfer with the GT500's. But at 6.6 lbs per gallon of gas, you're going to be increasing your race weight. With the Terminators, 3 to 4 gallons, (about a 40 lbs weight savings when compared to 10 gallons in the GT500's), was totally acceptable without any risk of fuel starvation. And with the heavy-ass IRS, wasn't as much of a benefit to put weight over the rear tires on the 03/04's.
