The alu shocks for M18 are not yet available but I know they are on the schedule, though no exact information, no release date. If there will be any news concerning the shocks, you will definitely find them on XRAY home page.

Thinking about the current mounting of the shocks I think oil filled could be a problem....

If the shock is to slow it could turn itself out of the balljoints on the chassis....
To do it right you have to lock them like HPI did on the MRS4

talking of the suspension - is Xray going to release anti-roll bar set for m18?

The suspension arms seem to be prepared for anti-roll bars (I mean the ball heads on the arms)...

some people try to do the anti-roll bars on their own:

That makes perfect sense. I wonder if thats the real hold up (ie they designed themselves into a corner).

But wouldnt the a-arm droop screws possibly help to alleviate this if they stuck with longer springs (so car rides at full ride height always)? Not a perfect solution. But else a two stage piston that has no dampening decompressing.

Playing with thick silicone differential greese a dampening is possible:

I came up with this (because it would still allow quick shock adjustment versus having to unscrew anything).

A: A new front and rear shock mount via new bumper and stock chassis that has a area to screw in a partial "c" clamp for the shock bottoms. "C" because then you could still pop them off to use the other holes. (They could offer that c clamp mount for the xray graphite chassis separate).

(See attached picture)

Negative: Requires new chassis for stock users, and at least a new front bumper and shock holder for aftermarket.

Well, the clampthing can also be made as an optionpart to screw on top of the current holes


By the way, maybe the balls on the lower suspension arms has something to do with the oil fillesd shocks....

I think I remember something specifically at some point that those are for sway bars (on the arm).

The problem with yours and Penquins method is of course you loose any adjustment via changing the shock angle. That and you shift more outboard weight, so the car leans more (I realize is only a tiny bit with the stock dampeners, but oils would make this more apparent).

Also, wouldnt you run into the same problem? Thicker oil, with decompression too quickly with the shocks acting too slow, the shock balls might fall out of the upper holes. Especially a bumpy on-road track.

As I did write before, some diff greese is working perfect so far as you can see on the video. Using lighter springs or a stiffer dampening could give me the same problem.

But mounting like these can give you a shocktower like a 10th scale car with more optional mountings, no need to use the ballcups.

I agree with oXYnary - there are however two positives of this slolution:

1. adjustable camber
2. adjustable caster

I wonder if those shock will be as good as the ones GPM was making for micro RS4. I had couple of sets of RS4 shocks from GPMs x-shock system and I converted them to use on my M18. Then I ordered new shocks they have for mini-z. Major difference is lack of bladders inside shock cups.
Here is a pick of shocks on my M18.

Actually there is no news as during designing the M18 PRO there were several considerations being made but at the end standard shocks which work still good for this kind of car and for this concept were decided for. The alu shocks are still on the "task list" but to be honest there is exact date or schedule for it. As soon something should change or there will be any news I will keep you guys updated. Sorry for no good news.
