Uprated rear springs

[RogerL]

Surely the back end of the car pitched up and down just as much when not towing but with the boot filled to the brim?

No idea, I never drove it like that. When I initially complained to the Vauxhall dealer they contacted Vauxhall UK who suggested fitting springs/dampers from one of the German models - this did improve things solo but not towing - I've no idea what the difference was between UK and German models of the Astra but mine was a saloon version, exceedingly rare in the UK.

Best to ask a Vauxhall dealership that one.

So all our answers failed the OP😜

Getting slightly off the thread, we bought a Vauxhall Cavalier Coupe, ex Vauxhall owned, it turned out to be a Hybrids model for the Swedish Market, different everything, mirrors, camshaft, valves, heater matrix, only found out as my uncle was in the experimental section and checked up on the serial numbers for me.

So everything can be different according to areas.

It would be unusual for the springs on the left hand side and right on the same axle to have the same spring rates. This is because the kerbweight distribution from wheel to wheel can differ significantly. This must be taken into account when fitting alternative springs.

Every OEM spring I have ever replaced has had the same part number for both right and left hand side so must be the same.

Mine is a 1957 Ford Ranchero, a relative of the Fairlane.

Same here, never seen them handed.

With all the round abouts one would expect the nearside spring to be stronger. LOL!

It's not uncommon on front-wheel drive cars for the front springs to be handed because the engine is offset to one side, especially if the engine is offset to the same side as the driver.

Rear-wheel drive cars are more likely to be symmetrical.

That might well be so, but not in my experience admittedly from many years ago. But surely in terms of the thread and towing, we are discussing rear springs.
