What kind of wheels are you using? Are all of them powered?
You're struggling to overcome the force of friction that's opposing your skid-style turning. To fix that, you'll need to:
A) Reduce the friction between some of your wheels and the carpet.
or
B) Shorten your wheelbase somehow
or
C) Gear your robot lower, trading speed for more torque to help overcome the friction.
At this stage, I'd recommend option A. You may have success with C as well, though. ~8.5:1 is a really fast gear ratio for 8" wheels. You might want something closer to 12:1.
