2bav, was that what that was? An apology?
You guys want to talk tech, let's talk tech.
First question, who here knows what is wrong with our Mustangs front suspension geometery? Do you know what happens when you lower the upper control arm an inch? AND do you know why you are doing it?
I guess that was more like 3 questions.
Here is a fact. The distance between the mounting points on the spindle, vs the mounting points on the car of both the UCA, and the LCA is off by a little more than an inch. This means that when the suspension travels in it's full cycle, you have changes in the caster/camber of the tire.
Now lowering the upper control arm puts the geometery in better shape, however it also puts the ball joint in a bind. If you are only going down an inch, it may never give you any problems, but again the UCA should be shortened if you are going to lower it to provide optimum performance from both the ball joint and the arm.
However I am sure no one here wants to try and shorten the factory arm, and I would NOT recommend doing it either.
Another problem that the factory stamped arms have is flexing during hard cornering. Many people have boxed in the arms to stop this, and that works great, but it still doesn't correct the problems discussed above.
You can box in the arms, buy the negative wedge kits, bump steer correctors, lower the control arms, and get in the ball park. However why not just fix it at the source, and put the geometery in it's correct place?
Money is probably why, but if you are seriously going to race your car, money shouldn't be the issue.
If you are just going to drive the car on the street, then when or why are you going to go fast enough to NEED to correct the suspensions built in faults?
I plan to run my car in the Silver State Classic. I have a very good reason for doing what I have done with my suspension. The question everyone else has to ask themselves is this; will I ever NEED the high dollar stuff?
