M3 control arm track increase & tension arm idea

[tree233]

Hey everyooone

Has anyone measured the track increase from the M3 control arms? How much longer are they than stock?
It's easy to find info on the camber increase, but I can't find any info on the track increase...

Also wouldn't the ultimate setup for track driven cars be the Meyle HD tension arms, with the bushing replaced with a spherical bearing? Due to the HD having a larger stronger ball joint on the knuckle end.

On the OE & M3 tension arms, the rubber bushing would take most of the shock, so replacing it with a spherical bearing would put more strain on the outer ball joint... therefore having a HD outer ball joint would be ideal! And since there's no geometric difference between M3 & non-M3 tension arms (please correct me if wrong), this would give the best result. I.e. performance & longevity
