It doesn't take rocket science to know that less weight equals greater performance. The lighter the car, the less power it takes to get it moving. During the build, and throughout our track tests, the weight of our '11 AMSOIL GT has not been something we've paid much attention toùwe never even took the spare tire and jack out of the trunk! Now that the car performs consistently in the mid-10-second range, it's time to shed a few pounds.

Until now, our AMSOIL GT has seen quite a bit in the way of modifications. The rear suspension has been upgraded, wheels and tires have been changed, the interior has been given a redesign, and added power comes from a Ford Racing supercharger, Kook's Custom Headers' full exhaust, and custom tuning from VMP Tuning. All of this equates to a best e.t. of 10.65 at 128 mph.

The addition of some BMR Suspension rear suspension components improved our 60-foot times but added a little weight. This month we turn our attention to losing some weight and dropping our e.t.'s with the help of BMR Suspension front suspension components and a Flaming River manual steering rack.

We started by putting the AMSOIL GT on the scales in the same trim as the last time it went down the track. (Editor's Note: Tire pressure was set at 35 psi in the front and 24 psi in the rear, which will remain constant for both the before and after weight. The tires distribute the vehicle's weight, and as a tire's pressure increases or decreases, the load that tire supports [and the tire diagonally located from it] changes. This can alter the corner weights and ultimately how the car handles.) In race trim, the GT tipped the scales at 3,622 pounds without a driver. Although not horrible, there was room for improvement.

We headed to Bayside Autoworks in Spring Hill, Florida, where Greg Fenton made quick work of removing the stock front suspension components. The K-member and A-arms were replaced with BMR's tubular K-member (PN KM018) and adjustable A-arms (PN AA026). While under the car, Fenton also replaced the stock radiator support with BMR's tubular version (PN RS002), which is much lighter than the stock support.

After the suspension changes were complete, Fenton removed the Optima battery to relocate it to the trunk. This gives you better weight distribution when launching the car at the track. The batter was relocated using Summit Racing Premium Battery Relocation Kit (PN SUM-G1231-K).
