A 6WD drop style should turn on a dime. If it doesn't, there may be other problems. Ways to fix a non-turning one include: increase drop (not applicable here, you may even have too much, generating a huge rock), add power, and decrease traction on front and/or back. 330 (one of the champions in 2005) once tried six high-traction wheels. They didn't like the resulting maneuverability, so they put kit wheels on the front. Problem solved. They had both front and back less traction in two different years and never had a problem.
