    Are you referring to the body mount(short one) and the tranny mount(long one)?

    O.K. There are three different kinds:
    1) long arm/mounts to the tranny
    2)long arm /mounts to chassis
    3)short arm/mounts to chassis

    Whats the difference between these 3? I know that the tranny mounted one has some drawbacks, but I am mostly concerned about the long and short!

    This is the short style that I have>



    Thanx Y2K, for I am now able to post pics again!

    difference = its length...
    on a more serious note... short TA is good for acceleration, while a long one is good for braking. if you're into drag, a short one is the answer, if you are into braking and handling, a long one is the way to go.
    Can you get the best of both worlds ? yes... provided you pay the price for a GREAT product... a proper decoupling TA, such as http://www.unbalancedengineering.com/Camaro/

    With short TA, you will get major wheel hop, worse than stock when braking. if you thought the occasional wheel hop on acceleration was bad... this one is like a giant playing basketball with your rear-end.

    also, the advantage of having them mounted to the frame is that you don't put load on the tranny's casing.

    Glad to help you

    I knew the chassis mount one removed the stress from the tranny but didn't know the short one was good for accelerating while the longer one was good for braking. Good info, thanks Eugenio!

    I never noticed wheel hop with the short one!

    O.K. So how does a short one decrease cornering? How bad will it be? I did notice a slight increase in cornering!

    How does the decoupling TA work? Does it slide up and down?

    basically, with a long one, it allows to have have better squat and load on the rear tires, that give you grip. Without that, or with less of it, the rear end becomes very light and can easily go out of control (wheel hop) with any imperfection on the road or by simply having the wheels brake harder than the engine rpm's are able to go down while in gear, causing a fight from the tranny vs the brakes.
    If you haven't experienced braking wheel hop, you haven't braked hard enough.

    for cornering... with more grip and control while braking it allows you to better transition into a steady state so you can take your turn better while being more stable as well... for handling, you need more the braking than on a drag-style setup.

    So, a short arm could drastically decrease the cars handling capability?

    yes if you intend to think about trail-braking or doing track time.
    The thing is that it's rare to find a mod that will help both handling and drag @ same time... UE TA is one that does that due to its design... but it ain't the cheapest TA, though... mine is going on within the next week or so.
