Hello all,

I'm noticing the car bouncing/wallowing a lot recently. Setting PASM firms it up a bit, but not as it once did. The car has 69000 miles on the clock now so I'm thinking perhaps it's time for the shock absorbers to be replaced.

What shock absorbers do you recommend? I'm considering either Porsche original parts or Bilstein B4 gas. I understand that the original parts are made by Bilstein so I'm at a loss to understand the difference between buying Porsche original and Bilstein B4 gas. Does anyone know if there is a difference?

Also is it worth the upgrade to Bilstein B6? Or will it make the ride excessively harsh?

Thanks in advance for your guidance.

I vote for what we cal RoW 030 in the US. Just make sense as original engineered equip and that is what I will do when my suspension needs replacement.

When one of the OEM shocks on our '05 997 was loose, the suspension shop I talked to said even though Bilstein makes the OEM Porsche shocks, the Bilstein replacements are much better. Not sure what the options are for PASM, but based on what I found out, I would go for Bilstein HD shocks over Porsche branded. The dealer replaced the one shock under warranty, so I didn't have to pick. I think the Bilsteins have a lifetime warranty. I don't think the HDs work with PASM, though
