Correct Oldblue.
I guess it's just the angle of our picture(s) that can be misleading. One coil wrap on one end of the front springs is a little smaller.
Here's a different angle shot.

It's been 5 years since I installed the Canucks but I do recall the smaller top winding.
Now according to Don's compatible chart, it's a matter of install and hope for the best!
In the OP's case I'd order front springs for a diesel model as the spring rate should be higher

I was thinking diesel too. But, I don't know why? It is the same block, same frame probably the same weight.

Do remember that early on the Cobalt front springs did not work on HHR, but HHR works on Cobalt.

Hello

So i need to tell in the shop the measurment of the oryginal spring so the shop can find the correct one cause the springs have different hights.

So the spring uses 14 mm steel wire
Its: 153 mm wide on the bottom
High: 314 mm ? Zafira - 310 mm / Vectra C - 304 mm

My springs are the oryginal ones but they are used by milage and years so they are 10-15mm lower (on the workshop the computer said the are used by 25%)

And whats more interesting on Polish market there are rear springs that are recomended for cars with LPG!, i was wondering why, and the outcome is that the LPG tank weights ~60kg and the fuel another 50 kg so the back so the car is always ~+70/+80kg on rear axle. Im learning every day something new

EDIT:

Zafira springs front:
REAR

Well those front springs, there is a smaller coil wrap on top and on bottom. So they may not work.

Your car looks really nice. I like the grille the most. Congratuations on your hard work and research. This is the place for help...

Did you get the ride height you wanted? I can't tell for sure if the rear is sagging low or not.

Hello thank You! I didnt lift the car yet Now im producing them, there is a company that makes springs for You own use with with documents all legal, but we are stuck in place with spring thicknes, and the problem is to get the right weight for the spring to lift... I made the spring on hard steel wire and the car was lift by 7 cm, so its out of producer suggestions so back to the drawinboard... meanwile im looking for oryginal lift springs and the question, i found those



they look ok, lifting by 3 mm but made for ORLANDO :/ what do You all think ?

And when ill finish all the mods i will send the photos new rims and tyres already bought.

No i have to place it all together

Those springs are for a kit to lower the car 1 inch or 25.4 mm
