Spring Steel, Spray Paint, and Salvage: Our Anti-Roll Bar Brackets Get a Makeover

We have a friend named ‘Josue’ that we call ‘Sway’ for short. We can count on him to not let us down, unlike these sway bar brackets have.

Long term viability was not our strong suit in the early days of turning our once daily-driven sex-mobile into an inbred racehorse. Midwestern winter driving and near-SpecE30 suspension mix like Virgos and Scorpios. Which is to say that astrology is all made-up as it goes along and we shouldn’t have been driving this car in the winter. The parts that took the beating in particular were ones with a thin, eBay quality epoxy coating or none at all. In other words, all of them. Since we took the front ST anti-roll bar out with the fingers-crossed promise that we’d refinish the brackets, we took the opportunity to do just that in between some work on one of our significant-other’s work-and-school-mobile.

If you’re familiar enough with stock E30 suspension, you’ll notice the differences immediately. The original bracket leverages into place inside of the front subframe and then bolts into place to semi-permanently secure the bar. Because the replacement performance part is slightly larger in diameter and experiences higher torsional forces (that’s us making it up as we go), it came with a special bracket assembly that helps brace it flatter against the subframe with a large backing plate and a bracket that bolts into the original bolt hole. It also dual-purposes one of the subframe bolts.

Step 1: Safety First, Second, and Fourth (Third is Lunch)

As with any operation involving swinging phallic equipment attached to something with too much energy, you’ll want protection. Since we’re using our Harbor Freight bench grinder with included Harbor Freight wire wheel, safety glasses, underneath a face shield, behind ballistic glass would have been the wise decision. But for now, all we have are safety glasses. Gloves are generally not advised for using with rotating equipment, but since the actual bracket portion of the bracket assemblies are awkward to hold, we took the risk. Refinishing the other parts of the bracket was easier because of their straight-forward shapes.

Step 2: Stripping – Taking it all Off to Get Us Through Vocational School

Foreseeing difficulty in attacking these with the bench grinder, we took a whack at them with a nylon wheel and a hammer drill. The nylon wheel had been great at removing the surface rust on our cast iron lathe chuck because it removed it briskly and without damage to the chuck itself, but against the thick rust of our unknown-alloy steel brackets it was almost useless.

To the bench grinder we went. For the brackets, we made sure to get to the insides, outsides, and sides. This would seem obvious, but it’s easy to get caught up in this oh, so shiny metal as it appears before your eyes that it’s easy to skip the quality checks before you move onto the next piece. The part wasn’t as difficult as we expected it to be, but it did take some unusual angling to get to all the nooks on the piece. Specifically, on the outside of the bracket where it bends at 90 degrees. A tip for wheeling the smaller components like the washers and the fasteners; place them in a set of locking pliers. For the nuts and bolts, we spun them together with a fair amount of hand-tightness and ran them against the wire wheel without touching the threads. You’ll remove the special coating that accompanies hardened fasteners like these and will make them more difficult to remove the next time you need to (sometimes even with the application of anti-seize materials!).

After about 20 minutes of tiny projectiles to the stomach and a podcast we couldn’t hear over the drone of the bench grinder, everything was looking as if it had been freshly cast in a medieval blacksmiths forging facility. Blacksmithery? Correct us in the comments. Someone. Anyone. Please read our blog! Anyway, on to paint they go.

Step 3: Epoxy Paint Me Like One of Your American Anti-Roll Bar Brackets

Previous projects on our Alfa Romeo Spider left us with more than enough black epoxy paint. We double-fisted each pair of components on some bailing wire and coated each one three times. Normally, we wouldn’t coat the threads of a fastener with paint because it can negatively alter those threads capacities to have torque applied to them. In other words, they won’t tighten no good no more. But since we had the nylon nut already covering the only area of thread that it would ultimately be engaging, we went ahead and painted it with the intention of it being a rust preventative maintenance.

While we let them air dry between each application, it’s important to let them cure for whatever period of time is suggested on the back of the can. Since we won’t be installing them again any time soon, we let them rest on the bench to do the requisite curing, hoping all the while that they spring to life the moment we close the shed door and go on a Toy Store like adventure in the time it takes us to eat, sleep, kiss our loved ones (and pets), and return to the shed for the continued torture of not being inanimate objects that become sentient in the absence of people.

We hope you had a happy holiday season and that you slayed many no matter what belligerent you fought for in the war on Christmas.
