Thread: X Arms

I think forum members,
rrturboD And skiboy both have or had X arms on their vehicles.
They may be able to give you some feedback.
I have a pair coming soon for one of my D90s.

Regards,
Mike.

I think Brendan may have them?

I believe Brendan has a rose joint rather than an X Arm.

I may be wrong, however I think I read somewhere that BrendanM has Johnny joints rather than rose/heim joints.
To the best of my knowledge, Johnny joints are able to be legally engineered, whereas (as far as I know) rose/heim joints are not.

Regards,
Mike.

All coil solid axle rovers have trailing arms in the rear except for d2's which have radius arms
The x arms look to be unnecessary
A standard or superpro bush will cycle a 12" shock easily with only cranked arms
In fact the roll stiffness in the rear trailing arm bush helps/forces the front to articulate
What length shock are you using?
What upper shock mounts are you using?

No pics of xarm/joint specifically, but hope this helps...

Hi David, The shocks, shockmounts and springs are all standard factory items. The reason I am interested in the X Arms is I am going through bushes very quickly. The car gets regular heavy off road use which is when the wear is occurring. I had thought about poly bushes, but in this particular application thought that the stiffer material may transmit greater strain through to the chassis during articulation. The following photo illustrates the kind of wear that is occurring:

As you note, I should have referred to the links as trailing arms rather than radius arms.

As Dave suggested, Super Pro bushes in that spot will help enormously.

As most of us continuously point out, SP bushes aren't stiffer than rubber, and the design is so far superior to the OE bush there it isn't funny.
