    Hello Forum,
    Obviously you can't drive my 360 to give me a firsthand opinion, but... if the car has a loose/boaty jerkiness after switching gears or stopping and going, what you do think needs to be addressed and potentially replaced?
    I'd like to "tighten up" the feel of the car a whole bunch, and it just doesn't have that right now.
    I recently installed a brand new clutch and the "upper gearbox support" replaced during the clutch service.
    But between new lower engine mounts, ball joints, and bushings, what do think will tighten up the car the most by replacing, in your experience?
    None of these parts have ever been replaced before on my F1 360. My mechanic said the old upper gearbox support he just removed from the car was completely shot and dated from 2003!

    Start with the engine mounts if their date/mileage is unknown, especially given the upper trans mount was just replaced since weak engine mounts will work that new trans bushing hard. I discovered my passenger side engine mount was no longer 1 solid piece upon removal.

    Just a thought, You may want to check your tires, air pressures, damage, excessive wear, etc...

    Good Luck to you!

    I felt that on my 348. Turned out the gearbox 4 bolts all came loose and the gearbox was hanging by the half shafts. (Mistake from previous owner)

    Apologies to TF for being the one to post a video, but…

    Every time I see this thread title, the following song starts playing in my head:

    agreed on starting with the engine mounts, but it's likely to need all of those things replaced sooner rather than later. and i bet it feels like a whole new car once you've done it all.

    Engine mounts and transmission mounts typically give the feeling that the engine is bouncing on the chassis, especially on throttle lift. BUT - if you are going to do it anyway, Challenge Stradale mounts are kind of cheap and will change the feel of the car. It will be loud and the vibrations will be extreme when idling, but the driving experience will improve significantly.
