Jmat, the guys are right, you shouldn't need to remove the ground effects, just use two (or more) pieces of wood. Typcially it's not the approach height that's the actual problem, but rather the approach angle.
The SVT is the second lowered car I've had and both have had numerous aligenments done. My alignment guy has a couple of short pieces of 2x6 to put under the ends of the ramp a couple of inches under the ramp ends and about 1-2 feet sticking out toward my approaching car. Because the ends pivot the wood reduces the approach angle but increases the approach height. When the front tires go up on the wood this brings the approach height back to normal.
On some ramps I've run into clearance problems on the angle after the front wheels have gone on the ramp and the car would bottom out on the frame around the position of the front seats. We solved this by backing up a little (front wheels just past the ramp and on the hoist itself) and placing two more pieces of wood in front of the rear tires so as the car moved forward the rear end raised.
You need to make sure you don't run off these rear ones before the ramp as you might still not have enough clearance.
If your alignment guy doesn't have these sophisticated precision pieces of wood
, you could always go to Home Depot or equivalent and get them to cut an an 8 foot piece of 2x6 into 4 pieces (easy to carry in the trunk).
