Rear springs

Has anyone got a recommendation for standard  rear springs ?

Seen Kilen on EBay which keep cropping up on search

Any suggestions as mine I've decided have "sagged" as slightly lower at back now and springs are slightly loose - can turn them freely  if you jack wheel off ground 

The rear springs are not under a lot of load when wheels of the ground,.
You don't need spring compressors when replacing them, it's usually the rubber mount ontop of the rear strut that squashes over time and can give the car the low back end look.

If you look underneath the wheel arch you should see the rubber bush between the body and strut

Yes that's a thought 

Just assumed the springs had created the issue with car being sat so long over the years without use.

I've got some spare rubber bushes so will take a strut off and compare the thickness - as you point out new ones aren't much anyway but it'll give an idea if they've squashed up 

Thanks 

Bought a pair of new springs for rear this week.

Stripped the O/S rear unit off car and got spring out - pic shows the existing spring on right is quite a bit shorter than the new one - so hopefully this will fix the squat position at rear
