    Default R10 motor supports?

    Calling the knowledgeable ones, again.
    I've heard conflicting opinions as to whether or not the supporting "braces" between the motor and bell housing are actually necessary.
    Is it a case of: "The factory wouldn't fit them if they weren't necessary", or
    "They fit them just in case", to cater for worst case scenario?
    Has any body out there had any good or bad results resulting from leaving them off?
    Thanks in anticipation,
    Henry

    I don't find it a too bigger problem to put them back on so I just do and don't worry either way.

    Hi
    No direct information really but both these statements are true.
    Why would you not fit them. Five minutes work and a few grams weight
    Lots of cars from all brands have them.

    I am from the "factory wouldn't fit them if they were not necessary school" so why not fit them? Perhaps they are only necessary under extreme circumstances so perhaps an extreme circumstance may occur. Fit them!

    Simon will probably chime in here, but the reason they may be on our cars is because we got the Tropical/rough roads versions. Were they fitted to all versions??
    If you are always driving on smooth highways these days maybe it is safe to leave them off BUT, you are also bolting an aluminium bellhousing (which are getting quite hard to get hold of) to a cast iron block so like others, I think 5 mins work to avoid possible problems from vibration etc to be worth it.

    The gearbox braces are not just "rough terrain", they are fitted in normal conditions as well. I have had to replace 3 bell housings (broken) where they were not fitted or had not been tightened properly. One case was so bad that the spigot shaft was worn excessively that the entire gearbox needed rebuilding.

    I'm of the case the factory fitted them for a reason !!!!!

    My first modified Renault was a 4CV and I took the 750 out and bought a secondhand 1108 and gearbox. Skimmed the head to high heavens, fitted the hottest cam available and 2 sidedraught Webers from a Fiat Scorpion and went dicing. Broke plenty clutches and what have you but never a bellhousing. See my picture that was taken in 1972

    Up to today I have never fitted any and have never yet broke anything. The G Turbo had one on the one side but that was more for the support that carried the weight of the turbo.

    Maybe I'm just lucky but it became second nature to discard them

    Frans, Nice wheels, I think they were made by Tiger, if I am not wrong.

    I'd love to know if someone has a street car R8/R10 with R12 conversion that's tried with and then without the braces to see if there's any notable difference to the buzzing through the car. My car never had them when I bought it and I've often wondered if they'd help reduce NVH in the car. I know they're pretty agricultural anyway but I'd be surprised if they were as buzzy as mine from factory. Oh, I do have new engine mounts too by the way but I haven't fitted my new gearbox mounts yet so maybe that's not helping.
    cheers,

    John

    My Floride S is noisy (annoying drumming) over 90kph and I am blaming the centre rubber gearbox thrust support. As I have broken the side gearbox mounts despite them being reasonably new. I also have a fair bit of negative camber that I never used to have so my thought that the top mount is sitting on the bolt (metal to metal) hence the noise. I am due to pull the whole unit out and check it shortly. Perhaps that is your noise as well J-man. Sorry this is not about side supports.

    Maybe it is Sunroof. I'll have to get off my derrière and change them! I'm sorry this isn't about side supports too
    cheers,

    Frans,
    Have you got the supports on your race car?
    I suspect that if the g/box and/or engine mounts are defective, then the supports will make a difference.
