Adjustable Rear Camber Arms

[zzyzx85]

i just replaced the ball joints on the GC arms. The old ones were some no-name brand. The replacement ones they sent were OEM. They were OEM ball joints with a flat spot where the set screw is positioned.

I already have Turner's "street" ARCAs but just wondering which GC ARCAs you got. Seems like GC has 3 of them: bearing, OE ball joint, and "cry baby" lol.

Not sure. They came with the car. Old bearing and new bearing.

That's the OE ball joint version. I figure the bearing version is best for racecars and dedicated track cars, but I have no idea how the durability compares to the OEM-style ball joint.

Surprised nobody is running fall lines.

They are, but on dedicated track cars. If they made a sealed version I would definitely run them.

Yeah. Not sure I would run open race-style bearings on anything short of a dedicated track/race car. Even dual duty cars are better off with a sealed ball joint IMO.

Although not in stock for another two months, these offer a lot of pro's.

Adjustable at the upright (don't need to loosen the jam nut at the subframe end).

Light weight aluminium

Large range of adjustment

Can fit a rod end boot to seal the teflon lined bearing from the elements for street or multi weather use.

Similar to what I have.

I'm running the BWs, with sealed monoballs. I always go the sealed monoball route, when one exists-- and, in this case, the BW design is as close to a copy of the CSL design as I've seen. Plus, they're alu. The non Alu versions are really quite heavy-- even these are heavier than I'd really like.

Got them in last week already from BW, very quick shipping. They are pretty heavy but at least it’s low and in the rear, and only 1.8 pounds heavier than the Turners which were my other option (but, rubber bushing). Everything else is pushing $500+ these days but BW has so far kept their price at $350.

I can't run monoballs on my car per class rules for autocross, which is a bummer, but it seems like Turner and others offer adjustable arms with standard bushings instead. Does anyone have experience with the SPC arms? At only $100 each they severely undercut the Turners and BWs. I'm guessing they're made of steel and do not have a cast/machined fork like the others do. If the only penalty is a bit of weight down low it doesn't seem so bad, but if anyone has any experience please share.

I think a concern with the steel SPC is that they wouldn't break if you were in a collision and you might bend other, more expensive things like RTA or worse.

I think the Turner arms are a good middle ground. I went with a rubber bushing even though my car is track only.

I may switch to a rod end when I refresh the rear suspension. Had them before and didn’t take long for the rod ends to start clunking.

Are all rod ends created equal?

[zzyzx85]

definitely not.

I went from TMS rod end ("oh cool, race car parts!") to TMS bushings ARCAs when I realized I would be putting 95% of the miles on streets (and pretty crappy streets too). In the end, I went for longevity, and ease and cost of replacing the OE camber arm bushing vs. a rod end.
