I am putting a 151 challenger on my 08 mtx. I wanted to know how far everyone has moved their skid back, and how much adjustment it left them.
I am not going to use brackets, but keep mounts in original sheet metal and wanted to keep the mounts as far forward as possible.
Thanks for any input.

I set mine back 3.5 inches. I also have 9" rear wheels. I am at the beginning of the adjustment. I could have gotten away wit 3.25" or even 3".
I am not sure if you will be able to bolt it all in without the rear plate. Let us know how it works out.

Thanks, I think the only issue with not using the plate is the bumper bolts. But that can be addressed fairly simply. I believe there is plenty of room for the suspenion to go up in the rear.
Unless there is something i am missing?

Drilling a hole in the existing plate will probably work but you will loose a little ride heigth. I am not sure if it will cause issues with the suspension. You may be breaking new ground. Let use know how it works out.

The phazer is plenty high to begin with. An inch in the back won't hurt anything, I think. Plus it will help keep the angle of attack flatter by not lowering the front. Raising the back gives the same effect on ski pressure.
I just cut the track tonight, so hopefully i can get the sled done this week.
Lash, so you went exactly 3.5 inches and are at the beginning of the adjustment? so you have what? nearly two inches of adjustment left or something? And are you using 9 inch wheels on the stock axle? or one of the offset axles?

Better double check. I think Lashcat has a 153 and you are going 151. 151-144=7/2=3.5
9" wheels instead 0f 7" takes up the inch difference needed for a 153 0ver a 151.

To do the math properly a 151 track should measure 151.2 (60 drive lugs x 2.52) and a 144 track should measure 143.64 (57 lugs x 2.52). Everything has to be a multiple of 2.52. Leaving a difference of 7.56 inches.
But the question is, if everyone is leaving for example, an inch and a half of adjustment left un touched, why not leave the skid forward an additional inch or so, and use the adjustment?
I just didn't want to start drilling too many holes in my tunnel just yet.

If my track needs adjusting in the future I have plenty to work with. I am at the front of the slot. Let us know how it works. I am sure there is more than one way to skin a cat.
As for drilling all the holes, I read a thread on here where a guy drilled his 5 times. He may be the one who figured it out and the rest of us have been using his example.

I went 3 inches and have most of my adjustment available. It actualy ends up being less than 3 inches the way i did it. I measured 3 inches in line with the tunnel then used a compass and drew an arch then used a level and went on a level line to the arch. The theroy behind my method was to keep the same geometry and similar ski pressure.

Thanks Tbyrd. did you use a plate to keep the rear mount level and then lower the front hole? or are both holes level on yours?
made a plate for rear attatch point of suspension, geometry would not stay the same had i not. Both front and rear holes ended up lower.

From what I have read the reason for the 1" drop is to maintain the right amount of ski pressure like T said. I was not thinking last night when I posted a reply. Sorry about that.
The was I did mine was I took the ruler out of a tri square and drilled a hole in it centerer on the ruler on one end at the 1" mark. I placed a leve on it. Then I place a small machines ruler with a square on it to mark my hole 1" down. Did the same on the other side. I drilled a small hole on each side then I welded in the plate on the back side. I then drilled the small hole in the plate using the hole in the tunnel as a guide. Then I drilled the hole to the size of the bolt.

gotcha, I am almost done with it. not sure if I will have to move some holes or not yet. But will put pics up when done.
