Rogue Engineering Adjustable Rear Control Arm - BMW E46 M3, E36 M3

What does a ARCA do?
An Adjustable Rear Control Arm (ARCA) determines the rear wheels' camber settings.  This is important on vehicles that are lowered or frequent the track.  Whereas the factory arms are adjustable, they have limited range because of the eccentric cam bolt design.  While lightweight in design, the "BBQ Tong" design of the factory arms cannot withstand the continual pounding of track and street driving forever. 

Our Design Details
We have modified our ARCAs over the years to continually improve their performance and function.  Our latest changes allow for a simpler, stronger part at the same time, allowing for easier adjustments when required.  However, when considering the design details of our arm, we specifically identified a few issues with other available arms:

 

  1. Adjustment points must be easily accessible.  When companies design their arm with simplicity at stake, they tend to put the adjustment points on the ends of the arm.  While the one near the clevis is easily accessible, an adjustment point near the subframe is not.  Typically, the adjustment nut is so far into the subframe you cannot clearly access it to tighten or loosen it adequetly.
  2. Having replaceable parts is a must.  Not all parts will last forever, and when they require replacement, easily sourced parts is key.  This is the reason we use a rod end that is 5/8"-18 (LH) on our ARCA.  In case it requires replacement, one can be sourced quickly around the country (outside the US may take longer).
  3. Mild steel parts do not hold up in NJ.  In our region of the US, our road are salted during the winters.  This wrecks havoc on steel parts.  Using parts such as aluminum and stainless steel help against these corrosive elements.  When appropriate, we balance the use of anodized aluminum and stainless steel in the design and construction of our parts.  It's more costly, but we want our parts to last.

 

Kit includes two (2) complete arm assemblies.  Professional installation recommended as an alignment is necessary to dial in the exact amount of negative camber.
