Can anybody help Taxi_G with his query regarding my stock ARBs that are currently for sale in the classifieds section?

Are they any bigger and/or stiffer than the ARBs off a non-vRS model?

Not that there has been much response. There are certainly different sized/strength ARB's but I'm not sure which is fitted to the vRS.

Best plan is probably to measure both and go from there.

non-VRS rear is 19.6mm.  VRS is 21.6mm.

 

You can make them a bit stiffer by re-drilling the drop link holes.

 

I've never looked at the front diameters but it's a fair bet they are a fraction stiffer on the vRS.

 

This might help

The whiteline rarb I had fitted to my vrs is very good but not sure it was £100 good ...

Slightly off topic but has anyone tried swapping the standard rear bushes for power flex on the standard Arb? Does this make much difference??

I fitted another brand of nolathene bush to the front bar of my Mk3 Cabrio.  It was fractionally better - about the same level of increase as fitting a "high performance" air filter.  ie: possibly the level of improvement was all in your head.  You'll get more improvement by shortening the lever arm.

So realistically it's more of a placebo mod! I'll leave that then!

If your D-rubbers need changing then use the poly bushes.  If the OEM D-rubbers are OK then you'll hardly notice any improvement.  I think you are going from about 50 duro for the black rubber to 100 duro for the poly bush.  As a component of a total system it isn't much.
