i have a 1997 sx vmax with long travel suspension and i wanted to drop the suspension out of the tunnel with some drop brackets. so i droped the rear bolt with some brackets and did not change anything else, but the rails were not touching in the front. so i was told by maxx perf that i needed to move the center bolt down half the disatance that the back went down. so i try this and no luck, so i decided to try moving the front w arm down and now it looks like the rails are lying flat what will this do to the ride. was this the right thing to do?
 
I was always told not to move the front. You can play with your limiter straps to drop the front.

Maxx perf told you right tho, what ever you move the back the middle goes 1/2 the distance.

How far did you drop it?
 
I left my center at stock and just dropped my rear 3 inches. You will run into problems with the track spearing your rails if you dropped the front down. I'd move it back up, and do the center 1.25 inches or 1.5 and see how it works. Maxdlx
 
that doesn't seem right to just drop the rear mounts, its gotta be changing the geometry of the suspension. It is setup to operate with the mounts in their exact locations. If it were my own i would drop the center mount half the distance i was dropping the rear.
 
Holic is right, ya need to maintain the geometry. If you look at the rear shock geometry (including those 2 flat control bars) you should see what I mean. However some guys just rotate the skid relative to the front mount. You can accomplish this by leaving the front, and lowering the rear but also moving it forward forward. Think of using a huge compass with one point on the front mount and the other striking an arc that the rear mount can be on. The center mount needs to stay at the same distance from a line intersecting the other 2 mounts, and the same distance from the other 2 mounts. If you are off as little as 1/4" the skid may not work right.

here are some #'s doing it exactly like you said.
3.5" rear drop = 1.325" center drop
4" rear drop = 1.625" center drop
