16:1 manual steering

Hope PST will come out with a 20:1 box to split the difference between the 16:1 and 24:1. I have the Flaming River 16:1 box with a small block and 19565R15 front tires. It's a ***** to turn backing out of the driveway with a stick. I'm about 230lbs and it's becoming a bit much. Simply not enjoyable to drive. I actually prefer the 24:1 factory box's feel but the front wheels jump all over the place whenever I hit a bump whereas the Flaming River box stays straight. I'm gonna try to set the caster to factory specs as I have tubular upper control arms with more caster built in. Although I haven't been to the track I have made a number of full throttle pulls up to 3rd gear with the 16:1 box and no issues.
