what you have to remember, this is a radial tire car. Radials Dead Hook , that means the car wants to pitch rotate or go forward..... this car seems to want to pitch rotate. It needs more weight on the front and less SLR , thats it. Honestly with a radial tire the travel and tight shock only helps but its not going to 100% fix this wheelie problem

THis car needs , LESS SLR, and more weight on the front. THEN he can really get agressive on the ramp and go LOW 8's or mid to low?5's in the 1/8

Powerglide , or leave in 2nd gear, (2nd gear leave will require a converter change)
Move the battery forward, move the fuel cell up front, sneak the motor forward 3/4 of an inch, lighten the rear of the car, fiberglass trunk lid, fibergalss rear bumper anything to change the weight bias will help
