The problem isn't the torsion bars! The problem is that your wheel tire combo is 3" taller than the car was designed for! By running the right diameter tire, your car would be 1.5" lower than it's sitting right now! By the time you hack up the fenders and adjust the Tbars enough to get it where it's close to being low enough, you'll have no suspension travel and the geometry will be junk. If you wanna go low with a static drop, 2" drop spindles are mandatory!
This car has 2" drop spindles and 1.03" Tbars from PST. Even at this height I've still got over an inch until I touch the factory bump stops!
