Rack and Pinion placement

Jon. I looked at some spindles and I kinda understand the problem. The tie rod mount is not far from the hub causing your 8" bag to be in the line of the R&P. I'm not sure what your spindles are made of but if it is possible I would add and inch or 2 to the front to relocate your mount hole. Are you building this yourself or having a shop do it?

stumbledin is Mike White for those that havent figured it out

You guys are all missing the biggest problem of all. The vehicle will drive straight down the road with little to no issues, but once you try to turn a corner the problem will become apparent.

It's called Ackermann and it is more of a nuisance than you can imagine in a situation like this. Read the Ackermann sticky in the suspension forum to get an idea what you are up against.

Thats it 100%. I am gonna have to do some research on this Ackermann issue before I figure out what to do.

The guy that owns the truck, works at a shop. They have never done a full frame up build before, but have bagged and bodydroped a ton of vehicles before. Since I have 10+ years CAD experience, he asked me if I would help him engineer everything before the build starts, so that it is done right from the start. Would rather do R&D on a workers truck than a customers. I am trying to soak up as much of this information as I can, as I have never done stuff like this, but once you figure out the 'rules' its all pretty simple, in a relative matter. Its just getting all the rules in one place thats hard.

Oww, my head hurts now. Will have to read that on a fresh mind.

its always best to base a suspension on some known "good" suspension. many aftermarket items are based on the Mustang II but it was never that good geometrically in the first place.

most leter model unequal length control arm setups are best for bags. setups with short arms like some imports or a Ranger dont have the correct amount of travel to allow for very good alignment throughout the whole travel.

the longer the A arms are the better the travel will be. unfortunately the engine gets in the way.

It appears that all is needed here is some adjustment to some things and everything will fall where it needs to. good thing asking before you are halfway through the build.
