    Hi all, just needing to clarify whether I can use both F355 challenge engine mounts (PN: 168358) AND the F355 gearbox mounts (PN: 159423) on a regular M2.7 F355B ?

    I've read the engine mounts are a good upgrade but haven't found any threads regarding the gearbox mounts so thought I'd double check before ordering.

    I been thinking about the same upgrade for a while, Michael. Yes, they're compatible, but I doubt the average person would know the difference. I don't think I'd bother having them changed unless my standard ones were showing signs of wear and I was due for a major. If you're working with a limited budget, I would save my pennies for a rainy day. With cars this old, rainy days are usually around the corner.

    It looks like your 2.7 car will need the different/additional spring washers and washers, too (#127496 & #14496609) if your car has the "old solution", but it's probably best to replace all the mounting hardware.

    Yes, I've had them on my 95 for 10 years. I believe they are the same on the 550.

    Yuuup they fit. Depends on what you consider an "upgrade"
    They are stiffer that's good for a race car but a street car I think I rather allow a little flex as designed.
