Our driveway requires backing into a restricted 90-degree turn. I'm shopping for a H3T, but it's 44 ft turning circle won't make the turn in one motion. I'd like to get the turning circle under 41 ft. Are there adjustable stops on the steering? Aftermarket steering knuckles? A high retaining wall prevents widening the driveway.

 

The H3T actually has a pretty darn good turning radius. Nothing you can really do to change it. You will hit the front sway bar with the addition of 315s anyway.
