Anybody have any DIY pictures of the modifications required to reinforce the steel control arms?

 

ive seen one- basically just a 1/8" plate on each side IIRC.

 

i have done well over a 100 sets for vw, audi, and porsches . you have to box in all 3 sides with 12 gage steel plating .do not worp the control arms when you weld it up . i made a jig to do them , its so i know there not bent before i do the job and to keep them from worping and bending then i do the welding . if you are using welt reds or rubber control arm bushings (stock) then its a waste of time to box them in ! your lap times will not change with this modification untill you go with a bearing kit which is the only way to stop unwanted deflection .
