Check those engine mounts

What did you replace them with? Hopefully with some Nylon ones instead?

Oh my goodness no. You would never want nylon or delrin in this application. You need something with some give. Nylon would probably crack or deform over time. Rubber or urethane is the way to go.

I'm restricted by my competition class rules, so I went with stock. However I do have a spare mount that a fellow ppbb member sent me, which I gutted and urethaned with 80 hardness urethane. I'm going to do the same to the mount that came out of my car.

And yes, the other two mounts are going to get a check this weekend.

If that's true then why are people always buying these Polyurethane motor mounts and bushings like these? These mounts are designed to limit the travel, reduce the chances of breakage, and put the power to the wheels.

You said nylon. Polyurethane is NOT nylon. Totally different stuff. Polyurethane would be OK for this application - but as far as I know nobody makes a polyurethane motor mount.

As I mentioned, you can make your own urethane motor mount using the old mount.

My bad, sometimes I can't remember the correct names/terms of certain parts. And yes, your right, no one makes them for our cars right now. Not sure why, maybe we could get a petition started to have a company start making them for our 986. A company called Motion Control makes some rather nice bushings and mounts.

Hi,

Polyurethane Mounts and Bushings aren't always a natural substitute for Rubber. In many instances the flexibility of the Rubber is factored into the equation, especially for some suspensions. Firm it up w/ Poly and you can actually negatively impact the function of the piece or system...

Happy Motoring!... Jim'99

One big problem is the market for Boxster parts is pretty small.

It's so easy to take your own mount and urethane it anyway. For $30 in materials and a couple hours of your time it seems a worthwhile DIY.

This is a common upgrade on a 911, check out www.wevo.com for best in class. Maybe we could get them to make some 986 parts like a shifter as well as the mounts.
