    • Baseline EVERYTHING before changes..
      It ran once before like that..
      Must be a reason why no longer is..
      Whatever the reason.. Your changes need somewhere to start from.. The bump steer might not even be there after the car has the M/T installed..

      • Of course.....just some thinking out loud there. Bench-racing as it were.


        More cleanup last night. Got the rocker panel 6x9 90's speaker hackery removed, and the spray foam dug out.

        Found more of those darn sticker cactus spawns of satan too. Grrr..

        This was in the rocker.........BEFORE they foamed it. Bet that rattle was hard to diagnose?




        "I don't often stuff beer bottles down my rocker panels, but when I do, it's O'Douls Amber."


        And what's this buried in the foam?



        Of course! Always need an opener handy!



        Removed the carpeting and padding, and one sides' tar-board. Of course, that's the side that it came off relatively easily, the other shows every sign of being a PIA to get up.

        But look! Actual steel for floors, not some iron-oxide wanna-be floor! This could be the first project car for me whose floors didn't come separately in a UPS box.

        • Front end: Flip sway bar over and flip ball joints over maybe? Might flip the spindle arms left to right to correct the ball joint taper?

          • I was wondering if you could re-taper the arms and put the tie rod ends in from the bottom. But I agree - try it first.

              I bet it'd put the rack within striking distance of the ground... I don't know this personally, but I suspect that racks hitting the ground is a bad thing.... just a guess, mind you

              • No, not a rack flip.

                Swaybar is contoured at the ends to clear the tie rods. Flip it over so the contour favors the other direction.

                The steering arms bolt to the spindles and are mirror images of each other.


                Swap them side to side and this will flip the taper and allow you to rotate the tie rod to the bottom thereby making the tie rod much closer to parallel with the control arm.

                Clear as mud?

                • Beautiful. That should work wonderfully.

                  • I'm skeptical.... I think the tie rod needs to be dead center of the steering arm.... flipping it over will, IMO, make it too low

                      • An old friend of mine who use to road race his 66 Mustang knew his stuff when it came to suspensions. His comment to me about bump steer was it's one thing to go into a turn at 30 MPH and it's another at 130 MPH. Basically it's how much you'll tolerate. I agee with the others. See how it is before doing anything. On the Mustang forum I hang out on, another guy who road races and sells parts under the name of "Opentracker" posted a really clever and simple way of checking bump steer. With the car facing a flat wall or anything flat, strike a vertical line on the wall. With the car at ride height, spring removed and a cheapy laser level strapped to the spindle with it's beam shining next to the vertical line you just drew, raise and lower the suspension and observe it's path compared to the vertical line. You won't get numbers to plot a graph but you will visually see the bump steer and go from there on any corrections if desired.

                        • Its not whether or not they are parallel, its whether or not their relationship changes as they swing through their respective arcs. It can be difficult to get to 0 bumpsteer, but through various devices you can generally get very close. I do know of certain combinations of parts for Mustangs where the tie rod end and steering arm have to occupy the same space, so not everything is easily fixable.

                          It's great that everyone is thinking of solutions, yet we don't even know the nature of the problem. Measure it, plot the measurements on graph paper and then we can find a proper solution.

                          • Yes you are correct Bob, but my assumption is that the tie rod was more or less parallel with the lca before the rack was lowered. If the rack and inner pivot is lowered 2", then the center point of the outer pivoting end (tie rod end) also needs to be lowered a corresponding 2". This is of course also assuming the Truimph engineers designed it with minimal bump steer in the first place! If not, all bets are off!

                            • One would like to think that a design that was meant to take the world by storm (in 1980) would have had good steering geometry......

                              But who knows. The British also think Lucas is a good idea.....


                              On that topic, just got off the phone with Rebel Wire in Tennessee. After last nights excavation on the TR7, I found lots of screwed up wiring. The main harness going to the back of the car apparently met up with the saw that cut the speaker hole in the right rocker, some that maybe one of those packrats found particularly tasty, and some that just are old and brittle.

                              Not to mention that every wire under the hood is painted blue along with the rest of the engine compartment.

                              I may just go with one of RebelWires' 9+3 circuit kits.
