Solid Steering Rack Bushings (Press Fit)
We will be making a variety of solid bushings for our new shop car but we decided to start with the ones most directly connected to the steering feel.
We designed a solid aluminum bushing with much tighter bolt holes, and a true press fit. These can be easily installed by putting them in the freezer for 20 minutes at which point they virtually slide in. We also took out as much material as possible bringing them from 143 grams stock to 54 grams. It doesn't sound like much but we strive to make every part as light as possible. |

Interesting. Please excuse my ignorance; what is the benefit of a lighter bushing in this location? What is the implication on durability for track applications? Am I correct in assuming that there is no downside, since the material is taken out from a non-stress point?

As far as the bushing being lighter, there is no particular advantage in that location vs anywhere else on the car it's just reducing overall weight. A few grams isn't much but notice its almost 1/3rd the original weight. It might seem like such a small weight savings that it's irrelevant but if you pay attention to the weight of every detail you possibly can you can shave hundreds of pounds 1 ounce at a time. For track durability this would be a one time purchase, you are never going to wear out a pressed in solid bushing. |

How many racks have you measured to get your baseline for the inside diameter? What have you found the factory tolerance to be?

That said if anyone ever has a rack that is way off what we measured we can easily make a set to fit. |

Nice!
Off topic, but I recognize your shop's name from my days in North Carolina (Went to NC State), and I believe you guys are big on the HorsepowerJunkies forum with some serious builds, including that bad ass F40 build you all did.... I was drooling over the welding work you did.

what is being done to prevent corrosion? especially the dissimilar metal galvanic kind at the interface between bolt to bushing and bushing to rack?
my experience working with aircraft landing gear components made out of alum tells me that your product cannot and will not last for the life of the car as you clam due to operating environment. even with extreme protective measure, unlike rubber, or polyurethane, alum will corrode over time. once it corrode, what is your plan to remove those bushings w/o making the hole ID oversize? putting it in is easy, removing and replaceing those bushing with basic hand tool is hard. |

I may be incorrect on this, but I thought with aluminum parts the corrosion to aluminum oxide essentially protects the underlying aluminum. So the part itself will be okay, but this may be saying very little about it seizing against other parts that corrode.

We're hoping around $40 shipped in the continental US

To be perfectly honest you're not going to see a huge night and day difference from this part alone (though it will help), like everything else chassis/suspension related it's the whole package that makes the difference. Quote:

As for replacing it, although there is almost no chance of that being necessary in a worst case scenario any decent shop should be able to handle the job easily. Quote:

Years ago I worked for a historic racing shop that serviced cars from road cars to race cars from the 50's and 60's. I could count on 1 hand the number of times we had issues with pressed in aluminum parts even 40+ years old. Thanks for the interest, we will be sure to update this thread as soon as our car is back on the road. Happy Thanksgiving! |

We just finished up our exhaust manifold flanges, and opened up a box of 321 stainless tubing. We will be creating another thread for that!
