    Nope, simply ran a vacuum line from the rear of the manifold to the CCV. I no longer have that setup as I went the GAS route, but it was very easy and quick. I wouldn't worry too much about oil getting sucked into your intake manifold if you just want to have a quick test run to see if it makes any difference.

    so i finally got around to purchasing parts. went with FSD's up front/Koni yellows out back (couldn't find a complete FSD kit...weird). went with the FCPEuro refresh kit linked in the 1st post above.

    question: i have the springs from my old zhp which have about 75k miles on them. current springs are believed to be original (178k miles). is there any benefit to swapping in the springs with lower miles? it's a "lifetime" part right? not sure if it would be a good preventive measure...

    Did you look for the Koni Special Actives? They're the new FSD's. I don't know how well the different front/rear will ride. Yellows are nice and tight all the time while FSD's will let the big bumps fully compress the suspension.

    No need to change out the springs unless you want to. They only fail if they rust and break.

    i did not look at the actives. i figure the front suspension compliance from the FSDs is more of a benefit while the rear affords a bit more stiffness since the front is what bears the brunt of most impacts. i dunno it was kind of an impulse decision lol. i could be wrong/crazy.

    I would try to match the same shocks front and rear.

    If you can't then go koni yellow or koni active

    I would recommend also changing the shock mounts (plus reinforcement plates if concerned with mushrooming).

    Well, you have to take off the springs anyway so what not go with lower miles if they are the same?

    I would recommend FSDs on all 4 corners. ECSTUNING has them available. I just installed them in my ZHP. They ride better than a new 3 series.

    well in the essence of time i went ahead and installed the FSDs in the front and Yellows in the rear. i am happy with the outcome. car handles super tight and body motion is controlled 100x better than the cheapo Monroe shocks that were on the car before. i can tell slightly that the rear is a bit firmer than the front but it doesn't bother me as the difference is negligible. i kind of wish i had gotten some springs like the H&R touring cup but overall it's minor. i'm happy with the setup.
