wicked vibration through-out entire car - 986 Forum - The Community for Porsche Boxster & Cayman Owners

The vibration is felt everywhere, almost like the car is falling apart.
But, it is usually only felt when cruising or dropping in rpms/slowing down. It is almost never felt when accelerating because you get past the "weak spot" (around 3200rpm) so fast you wouldn't even notice it.

can anyone else confirm this (especially my 987 brethren out there)? This crazy-ass, my car is falling apart, I wouldn't run this on a straightline, all over vibration is NORMAL? Wait, I thought I bought a Porsche - fine, german engineering????

Is there a hidden badge on the car that actually identifies it as being constructed in Tijuana???

A friend with an A4 had a similar kind of all over vibration and it turned out the be an ignition coil problem - something Audi ended up doing a recall for? Thoughts? I mean, is Porsche sending up a smoke screen because they're not sure why this happens? BruceLee - any of the 911's you have demonstrate a similar phenomenon???

to the dealer tomorrow - keep your eyes posted on Fox news (OJ got nothing on me!)

From another thread:

There's an issue in the 3000-3300 RPM range with the dual-mass flywheel that's standard on the Boxster. I feel it all the time, mostly in the seat. Mine started a few months ago. The problem is similar to a warped rotor, but since the flywheel moves so much faster it's a vibration you feel rather than a shaking like you would get from a brake rotor. The range widens over time and mileage.

Sounds like its time to upgrade to a Sachs lightweight flywheel and performance clutch.

yeah - if i'm replacing anything in this new car because it has to be, rather than because I want to for peformance gains, aesthetics, etc - than by golly I'll replace the car!

On the other hand, if this were a 75k mileage car or a 5+ yr old car that required a new clutch and flywheel because of normal wear and tear, my stance would be a lil different. But, crap - 4000 miles on a car that's supposed to be better than the domestics and asian imports and already has a rattle and hum (not courtesy of U2) that makes me think, hmmm road trip this weekend - yeah, maybe we'll take the wife's subaru!!!!

It sounds like a classic case of either demonic possession or aliens attempting to communicate with you via your Boxster. If the Boxster starts spinning around on it's mid-engine axis or you get the uncontrollable urge to mold your mashed potatoes into Devil's Tower, you'll know which for sure.

Glad I could help.

sd- in fact, just the other day, I began shoveling trash and dirt into my kitchen window after I swore the boxster moved it's front trunk up and down and in not so feminine voice - urged me to build it...

my wife promptly said that she wasn't terri garr and to immediately get the dirt the f*(& out of the kitchen!!!
