I would like to put a suspension with the TSL but I have 1.4 track.Because I do not want that the track touches the tunnel or avoids making it. I believes that I has to put it on the lower holes (on the bracket rather than on the tunnel) I am right?? And I am going to have to re-drill holes????

Audigy,
You can defenitly put your track to the braket that you were talking about. Only thing is that I reccommend that you also lower the front of your skid to match the drop that your giving your rear of the skid for clearance. If you do not level out your suspension, you will have an upward slope to your track on where it lines up with the ground. Unfortunetly to make up for that miss-allignment you have to compress your suspension 3-4 inches in order to make the suspension sit level on the ground when your sitting on it. Like mentioned above to avoid this 3-4 inches of sag, you need to lower the front of your skid to match how much you lower the rear of your skid. I have done this on my sled and I it makes my machine run like a dream on the ruff stuff.

Notice that I put my bolts through the very front hole on the braket located below your tunnel. That would be where you would want to place your skid at as well.

For the front of the rear skid, I had holes pre-drilled through the tunnel itself, but not through the re-enforced plate on the other side of the tunnel. this made it so you could not see the pre-drilled holes until you crawled up under your sled and looked at it from inside the tunnel. All I did was finished the holes through the re-enforced plate....and walla. No mesureing required. Hope that your sled is similar to mine, as you dont have the ett tunnel and may not have the pre-drilled holes in your tunnel to help you out with.
If that is the case, get back to me and I will take mesurements of where my holes are. Hope this helps.

Here is the end result.
