I hear what you're saying. Remember though, this rear has junk gears in it. If I knew I only had one shot, I'd really dial it in. However, this setup will only be temporary. I'm going to get it close and toss it in. Run it for a while and see what issues arise. Different gear ratio, different pinion angle...(?) I can correct any mistakes or issues when I do the next one. That one will be perfect. I'm just trying to make lemonade from the lemon 8.8 I bought.
4 link? Probably not. This thing is going to be a DD burnout machine with occasional track time. Not a hardcore race truck. I do see a set of Caltracs in its future though.
