Your car looks fine off the line. You should rethink the idea of getting more air. Once you front wheels are of the ground you have 100% of the weight transfered to the rear tires. What you should be looking for is the least amount of power to move the car forward the quickest. Look at the shocks for control. The Konis are fine. If you need to go futher you may want to look into converting them to double adjustables. The goal of the front shocks is to control the rise and fall of the front end. The most efficient launch is when the front end rises slowly and settles down slowly while the car is still accelerating. The rate that the shocks extend and collapse is dependent on many factors: Tire size, rear gear ratio, first gear ratio, T-brake, torque converter stall, vehicle weight, horsepower, track conditions, etc.

If you were to graph the front bumper during a launch you want a nice even rise and a nice even fall throughout the first 20-60 feet. You don't want the bumper to pop up quickly then fall slowly. you also don't want the bumper to pop up quickly then fall quickly.

Optimum weight transfer occurs when the front shocks are at Maximum extension.

Read up on Center of Gravity, Instant Center and Percentage of Rise. Find someone who can help graph this for you and you'll be on your way to a hard launching car without the unwanted air time.
