The tricks to building a really strong Lazer (I wish somebody would sticky this, type it a lot!!)
Firstly DON'T OVERTIGHTEN ANYTHING, JUST NIP IT UP!! Sorry if that sounds aggressive but I see so many people bottoming out screws then putting a load of extra compression into the joints, this stresses the plastic and WILL lead to a failure eventually.
1) replace the bolts that bolt through the tower mount, link plate and trans case with 18mm - 20mm long cap head ones (depending how high you space your tower up, I use 20mm as I have the front +1.5 & the rear +1.75). Put a thin plastic spacer under the heads of these, I use the ones from the shock sprue, same as I use to space up the tower. I prefer cap heads as they are much harder to round off.
2) places a small plastic spacer under the head of the single screw that goes the tower mount into the center of the trans case, make sure that the screw is long enough to just break out into the inside of the trans case but not long enough to touch the diff.
3) Fit the tower to the tower mount using slightly longer screws, not so long as to come all the way through the closed hole on the tower mount, that weakens it.
4) Do not use carbon towers or ali tower mounts, they transfer the loading to the trans case and that takes much longer to change if you break it.
5) Use bolts that are only just long enough to mount the shocks so that no thread pokes through the back of the nylock nut and fit the shocks like this ...
screw- shock bush - any spacers - plain nut - tower - washer - nylock.
This is totally opposite to how most cars build instructions tell you to do it but it does 3 things for you;
a) means that the loaded part of the bolt is longer so it will bend before leavering a failure on the tower
b) means your much less likely to crush the top shock bush by accident and end up with a tight upper pivot
c) means that you only have to undo 1 nylock per side to move the upper shock position (I play with this a lot)
Point 5 is particularly important on the front!!!
Follow this & you will be near bullet proof
