Bilsteins on a light rig?

[91Mav]

G'day fellas,

I'm looking at ordering some 12" Bilstein 5125's all round for my YN65 Lux but am worried they'll be too firm. It weighs 1350kg and the back will get even lighter when I remove the tray for a flat bed.

12" 5125's only come with 255/70 valving. Is this too much for the rear of the Lux? 12" 5150's come in 170/60's too. The remote reservoir is overkill for a play toy but will they be better? OR should I just get some cheaper shocks for the rear?

Thanks

I have some of the 10inch Bilsteins on the back of my LN65.
Im happy with them.

Alot of other Lux guys run Bilsteins front and back and are happy.

Cheers mate. I suppose I can just inboard them further if it's too firm for my liking.

I read somewhere that for max performance, you want to have the shocks almost straight up and down, instead of inverted too much.
Maybe modify the upper mounts.

What they meant by "max performance" is that for the maximum compression and rebound damping, the shock should be perpendicular to the travel of axle articulation. The best compromise for this is vertical.

What I was saying is, if the damping is too firm for my liking, I can inboard the top mounts. Basic trigonometry shows that the dampening can be reduced (which is what I'm probably after). 10* angle on the shocks = 92% effectiveness (if verticle = 100%), 20* = 92%, 30* - 86%, 40* = 74% etc. What I'm saying is, I can fine tune them by playing with their angle.

The issue is the more it compresses the greater that angle becomes .. so the shock looses effectiveness as it compresses .... not exactly what I would think was a good thing.

The axle travels both upwards and inwards during up travel, the amount depending on the height of the roll centre. This would help to negate the increased angle of the shock but it is a good point that I didn't consider.

Thanks
