Unhappy Lower Control Arms (coffin arms) question

Hello All
Ordering new arms from ECS Tuning and they don't seem to have different (coffin) control arms for the front and rear.
This is the Meyle arm they retail, site only specifics the arm is for left or right fitment.
That arm is also included in the control arm package ECS sells here.


Is this lower control arm interchangeable front and rear?

Thank You!

Strange some manufactures have different part #s for the front and rears, but after talking again with ECS they confirmed even Porsche uses the same part # for both.

If you get the ones with the offset bushing to correct caster they will have a right and left but you can probably rotate that bushing. It's not something I've messed with yet.

If it’s the hard rubber bushing like in the GT3 Cup control arms, it takes a special tool, or possibly a good bearing set to move them.
I have the special tool.
I turned a left into a right to have a matched set, which I gave away in the pay it forward thread.
But I think you’re correct about the ones with machined bushings.

997 and 991 have a taller central bushing therefore need a different diagonal control arm.

Tarett includes a spacer in their kits for this reason.

I just started a suspension refresh project yesterday using the FCP euro kit. All went smoothly until it came to the LCA and I cannot get it to budge using a pickle fork. Any advice? Or is it just a question of perseverance?

You need one of these:

Ball joint separator
There are lots of manufacturers.

Thanks for the reply. I have one but you can’t use it on the rear LCA. You need to use a pickle fork

thanks I’ll give it a try. Both the FCP Euro video and the 101 project book say you need to use a pickle fork.
