Thanks Corky.

To determine best option and check ground clearance, do you have comparative measurement of spacer tube lengths (between bushes) for SS1/Chevette Daewoo links?

Poly bush reference is useful. Do you have a preferred supplier for these parts or is it eBay trawl?

If you click on the part number above, it should take you to the cheapest vendor on eBay for that Super-Pro kit. Just check that the supplier is sending 8 X bushes, as some car models only use 4.

QRG price is £24 + P&P, eBay price is around £17 delivered.

I don't know the lengths of the tubes, but I can measure them and get back to you.

Just put my winter wheels/tyres back on and had a look at the links while doing it. The bolts are still straight and I think the poly bushes will last another year.

Hi Peter.
It would be useful to know what sort of mileage per year your car does. Plainly, a car that hardly turns a wheel from one year to the next is no indicator.

Done about 10k since the poly links were fitted - not a great mileage but 4 years.

Could some of that not be shocks Peter?
Yes could be, one has Koni Classics (with the ARB) the other has Spax. It just feels like the one with the ARB is stiffer at the rear when cornering.

IMO I think you can dismiss the issue of "fitting the arb upside down" as theoretically there's little or no difference between the upper and lower faces, and the horizontal-ness or upward-sloping-ness of the ends is entirely due to the drop link lengths. The arb should pivot fairly easily in the chassis mounts (with drop-links disconnected);the arb is only ever stressed when one wheel either bumps or droops.
I think the drop-link length can be determined by ensuring the arms are horizontal when the suspension is at rest; movement up and down will then result in an arc that introduces the minimum of bending forces on the drop links.

I've opted for Chevette drop link (thanks Corky) fitted with ARB bent ends facing upwards (as I found it). Drop link spacer tube in my original set-up measured 30mm whereas the Chevette spacer now fitted has 75mm length. I fitted the through bolt with its head at the bottom and find with suspension in neutral position it does not hang lower than the chassis so shouldn't present a ground clearance problem.

It will take time but if a problem arises I'll post an update.
