R36 OEM Suspension

[louiz]

The Bilstein B8 part numbers are front 35-122081 and rear 24-178006. Front strut mounts are 1KO-412-331-B and rear strut mounts are 3CO-53-353-C. I think these were sourced locally (not OEM) from Imparts.

Anyone knows the Sachs rear shocks part no. that fits R36 wagons?

I think the Sachs are OEM, so they would have a VW part number 3CO 513 049 - BS. But I think you could buy Sachs direct from parts suppliers like Pelican in the US.

I didn't want to go with OEM/Sachs because they won't last like Bilsteins. Sure they cost more, but you get what you pay for.

Nine months on I'm very happy with the Bilstein B8s - they suit the car. Firm but not hard.

Hey guys,

I know this is an old thread I’m reviving, but like the guys said on pg 2, the R36’s are getting on.

My suspension needs replacing, I’m pretty sure my rear springs have failed on my wagon.

I recently purchased KONI Sport active shocks all round and started with the rear - and it’s still terrible.
So i dont know if its a bad choice of shock or the springs are the problem.

Like the OP said, i pulled out my rear SACHS and pushed them down, and they never came up- so deff dead.
But in with the KONI’s and it drives like a mushy falcon. Any reasonable bump and there are multiple up and down strokes on the rears, it’s awful, and on the crappy Hume hwy, it tracks all over the place - meaning in those well worn divets I’m constantly correcting as the geometry is clearly all over the place. (New tyres and wear on the olds very very even for an R36)

KONI’s have been in for around 2000 K’s.

So seeking some advice and opinion on replacing the rear springs.
I cant seem to find anyone doing an OEM replacement.
I dont want coil overs and dont want to change the factory ride height of the 36 - very happy with that.
OK to go up in firmness doesn’t worry me.

Keen to get some input from the forum.

Cheers all.

I'm the OP here and I don't think you have a problem with the rear springs - they rarely fail. They can rust, break or sag, but it's not a common problem these days.

What you are diagnosing from your post appears to be an issue with the shocks/dampers. It's the shocks that control the springs up and down movement.

I suggest that you either get your VW specialist or a suspension specialist to have a look and test drive the car - you may have faulty KONI Sports. So it could well be a warranty job.

Six years on and my Bilstein B8s and standard springs are still going strong!
