Recommendations for Adjustable Rear Control Arms

[oceansize]

With the vanishing of m3forum.net I can't find what I need so I'm forced to ask a question that has been asked a thousand times before.

I'm looking for a good set of street ARCAs that are easily adjustable, reliable, and comfortable. Weight savings isn't a primary goal in this instance.

What would you all go with?

I went with the Turner street/track camber arms when I installed my Ohlins R/T coilvers. It's only been a couple months, but so far so good.

I personally like the Bimmerworld street/track rear camber arms. Most camber arms use stock M3 rubber bushings while the Bimmerworld street/track uses OEM sealed monoball bearing which are used on CSL aluminum rear camber arms.

Also the obligatory follow-up question.... is it worth it to run a rear camber arm with a rod-end joint versus a sealed monoball like shown above? For an aggressive/street/track car.

[pawa_k2001]

I don't like exposed rod end joints on a street car, the dirt and grim kills them. Sealed monoball should have a longer service life and does not need to be looked after.

Love my eibachs, made by spc. The aluminum ones. Rubber bushing. But they are pricey.

Turner's are nice too and on sale:

I installed SPC's over the winter and was impressed with the value. They are beefy and not light. Sorry to give you an out of stock item, though, and maybe BW can give a lead time: https://www.bimmerworld.com/Suspensi...36-E46-Z4.html

I didn’t know that about the inner joint being different on the CSL and the Stock m3’s. Is that BW arm the only one that uses that inner ball joint?

I’ve been using bushing end TMS rear camber arms for a few years, with no issues.

Yes, BW street/track camber arms that I linked above use CSL style monoballs. Most other camber arms either use rubber bushings or metal exposed joints.

Do you think using the Bimmerworld arm along with solid subframe bushings would lead to significant NVH?

I actually got Megan racing to try and they've been doing the job just fine for past 2 years.

I've had the Turner (rubber bushing) arms on my E36 for years and have been very happy with them. The single outer jam nut design makes them easier to adjust than SPC, etc that have two jamnuts on either end. They also offer individual replacement parts should you need them.

I personally like the Bimmerworld street/track rear camber arms. Most camber arms use stock M3 rubber bushings while the Bimmerworld street/track uses OEM sealed monoball bearing which are used on CSL aluminum rear camber arms.

^^ Little known detail.

Much like the modern shift in RTAB design (Dinan, SDW, Fall Line, etc) the sealed monoball are the best of both worlds. Last I checked CSL camber arms were NLA but they were about $700 per side before and were known to bend easily.

Bimmerworld and Ground Control are the only ones I know of who offer a comparable product with sealed bearing. I will probably be going with one of those unless Turner comes out with their own version...

I have Rogue, Turner and D2 Racing, and works great.
