    Adjusting the Macc Sponsons

    The instructions say up and forward is least aggressive, down and back is most aggressive, trying to find a happy medium. Has anyone played with these much? I want to put a set on my daughter's ski, but trying to figure out a good starter position that's one step more aggressive than stock on her VXS. Any ideas?

    Also, these have an adjustable "trim tab" feature. Has anyone used this to get the nose down on a VXR/VXS?

    Do they have adjustable backing plates or is that the trim tab adjustment you are talking about?

    Yes, the backing plate is slotted. On my FZR I have the backing plate in the middle of the slot and the sponson all the way back and down. I personally don't find this too aggressive and I haven't been pitched when landing sideways on a jump. The trim tab on the rear of the backing plate tunes the bow pressure. I like to turn so I set it level to maximize the pressure on the bow. You just have to take your tools with you to the lake and test, they're very easy to adjust on the water.

    If you look at the back of the backing plate there is a little "trim tab" that is adjustable:

    First ride with the sponsons were eh. Turned harder, but still slipped a little in some big turns. Also in the 20-40 MPH range it seems to walk from one sponson to the other. Hoping that can be fixed by putting the trim tabs down in the back. Setting is in the bottom right hole of the four shown above.

    Were you able to see if they helped with the bounce at all?

    I've got my ride plate shimmed right now, actually too much shim. I was able to do a full superman on light ripple with two bars yesterday and the thing didn't skip a lick. But my guess is the sponsons won't help.
