rear suspension amuminum control arms

[T0Pnotch55]

hi everyone, i am curious to know if someone makes aluminum rear control arms or if by any chance there are newer Mercedeses that might have similar suspension geometry to w124 and can swap aluminum control arms to w124 chassis

The only one I know of is the torque arm: See this post from GSXR in my thread:

The aluminium torque arm was identified years ago, as noted on W124performance back in 2007 (photo below).

For rear camber adjustment, I prefer the Megan Racing units. More info, and photos, are in this thread. Avoid anything with Heim joints (like Camber King).

Yup, what Glen said. No real need for any other subframe link upgrades. The links are robust as-is.

i was thinking more as an aesthetic upgrade, more for looks and maybe some weight saving
