Is anyone running the Gmod and dse arms?

I am trying to align the car with about one dgree neg. caster and three and a half degrees pos. caster, and so far I need longer c/a bolts and had to trim the c/a towers a little for clearance.

Curious what others have done?

The car feels great once its in a turn and it changes direction well but it needs a lot of attention on faster turns and going staight.

The steering box is old and stock so I guess thats next on the list.

I have the carrera shocks set on four front and rear and about 37 pounds of air in the tires.

You need more caster.... like around 5+. With a degree static neg camber you will want more + caster in it initially. I would just try and see how much caster you can get out of your set-up. -1* camber with +6 caster would be a good starting point.

The positive caster will decrease instability issues at higher vehicle speeds.

The required mod for the DSE system is of Kyle's own direction. Which is really doing the same thing as the Gmod, but works specifically with his control arms. The difference between the two isnt too much but his relocation moves the mounting point closer to the chassis centerline to reduce the amount of shim for the UCA....... which is a HUGE help not to mention the ability to use the offset bushings to get need caster increases without an inch stack of shims.

Is their a point of too much caster, and how can you tell?

Am I following you correctly, the "dse mod" involves welding the control arm tower closer to the engine?

Is there such a thing as too much caster? Sure, but you won't get there using DSE arms and the g-mod. The practical limit on positive caster is somewhere around 12 degrees, I run ~9 and that is with drastically different UCA. Typically you decide on a camber setting and then shoot for as much possible positive you can obtain without compromising the camber setting.

What do factory Benz's run? They have really high caster settings, IIRC.

That is the problem with non adjustable arms, you usually hit the headers before you get your needed adjustment.

Most MB run upwards of 9 degrees with most being in the 10-11 degree range.

Also, it just looks crude to have a freight train of shims on a longer bolt.

Does any one have a DSE jig or the specs of it?

The DSE UCA's are normally used in conjunction with their UCA mounts and coil overs.

Their Jig/mounts relocates the actual UCA mount closer to the chassis centerline..... and if you are using the arms alone, without moving the mount..... you are going to use a pretty fat shim stack.

So yeah..... you are going to need a longer bolt and pocket full of shims to dial it in.

Interesting ....
I just recently put on DSE UCA, 2 inch drop springs, and sway bar ( part of their kit ) but did not do the G-Mod or relocate any brackets. Will I be running into alignment problems ??

Should having them start off at -1* camber ... then seeing how much positive caster they can get from there be the best way to go ? I'm running a 225/50-16 tire.

Chris You should not run into the problems that I did because I did the gmod and you didnt.

I cant make alignment suggestions, I am still in the learning stage there.

Dave pozzis website has a good section on alignment specs.
