In reality, for you, the weight reductions (or any othe mods) will not pay meaningful dividends at this time.

The best bang for you buck is to get seat time. After you do a few runs, have one of the fast guys drive your car and see how much time you left on the table. I can almost guarantee you that that improvement will be much greater than what you can achieve by mods to your car.

FWIW-I was watching Truth in 24 and they showed the Race Engineer running the pit crew ragged to minmize the time the car spent in the pits for fuel, tires etc. He was asked why he focused so much on this. He said that the cost to reduce the time in the pits by seconds is orders of magnitude less expensive than mods to the car to gain a few 10'ths per lap.
