Advice on Powerflex inserts for transmission mount and passenger sode motor mount

Sorry if this has been asked before, I couldn't find an answer. It's time to replace my mounts and I stumbled across a post about using the oem mounts with the powerflex inserts.

Is there a need to purchase new mounts along with the inserts? Can I just swap the inserts for my worn out factory inserts? I don't want to waste money on new oem mounts if it's unnecessary.

Any advice is appreciated! Im going to attempt this repair myself, doesn't seem too crazy...

first, i would avoid running the OE rear motor mount. just get yourself a whoosh rear motor mount street spec... $100 + tax & shipping and you will get less of the motor smacking the firewall under significant torque. this is a very common first modification for FiST owners

I don't think you need to replace your OEM transmission and side motor mounts to use the powerflex mounts, but it would likely depend upon the condition of your OEM mounts.

I have the powerflex mounts you mentioned. They make a fairly subtle difference. I don't think I'd bother.

The rear motor mount makes a big difference in terms of the way throttle application feels, shifter feel, wheel hop, etc. Things to be aware of is that many of aftermarket RMMs have bushings which wear out quickly. Also, the rear motor mount adds a fair bit of NVH, especially in colder weather. I prefer the aftermarket RMM, but I'd probably swap in the OEM mount if I was selling the car.
