cause they are harder or so I read! so mean less movement of engine plus i think its more like 9.5hp  | | | | | 06-01-2007, 04:42 PM | #7 | | Senior Member Join Date: Jan 2006 Location: Cincinnati Posts: 890 |
The I6 mounts are much harder than the I4 versions. There isn't much reason to upgrade them unless you have the engine to upgrade with too.
You'll basically transfer more engine movement to the chassis and ultimately to your seat bottom if you install the I6 mounts on the I4.
I'd probably just leave them alone. __________________

I understand that they are probably made of a more rigid urethane, but there's no performance increase in doing so.
All you're doing is transmitting more vibration to the chassis. The motor may move less, but the drivetrain rigidity is limited by the guibo/flex disc anyway.
You're going to end up with a louder car, beefing up good links on a weak chain.
If it's that you don't want to replace them as often, give a squirt of WD40 every once in a while. It refreshes the rubber. __________________

my engine rocks like a fricking roller coaster and it sux I am assuming is the mounts! | | | | | 06-03-2007, 01:47 AM | #11 | | Senior Member Join Date: Jun 2003 Location: Halethorpe, MD Posts: 1,028 |
Aren't our mounts liquid filled? It seems like I read that somewhere. | | | | | 06-05-2007, 03:06 AM | #12 | | Senior Member Join Date: May 2007 Location: Seattle, WA Posts: 402 |
Just remember, if your engine is rocking "like a roller coaster" and you firm up the mounts, that energy will transfer to the car, and the car will shake. Check the mounts, but if it's not that, don't think of firming them up as an upgrade, unless you want to turn your morning coffees into a frappuccino.  You may have an engine timing/tuning issue if it's shaking as bad as you say. __________________ 1997 332ti - Don't even ask.
