3, Checking the rear spring left side:
Now I inspect the rear spring in detail on the left side.
Rear spring left side:
A lot of arms around the spring, the upper arm is the one to replace if you want to have a camber adjustment. More about that later. Above the stabilizer bar and behind the shock absorber.
Checking the spring, it's looks okay even on this side and no damage. I also count the number of revolution it has, 8.7. That was strange, 0.2 more revolutions on this side, I couldn't see that the right spring was broken. But it's difficult to see exactly how many revolutions the spring has, maybe the same.
The end of the spring at upper side.
Close up view of the top end of the spring.
At the bottom of the spring, the tip of the spring is buried in sand.
Here the spring ends.
I also want to know where the spring is attached on the lower arm, 21 cm from the inner pivot point.
And to the outer pivot point it's about 25 cm from the center of the spring.
Now I know the spring is attached about the middle of the lower arm. The car is on the ground now and the spring is compressed. The height of one revolution is 25 mm, it gives 50 mm at the wheel. The difference between the right and left side was about 11 mm, little bit less than 1/4 of revolution of the spring. If I want to lower the rear of the car by 20 mm I should have a spring that is 10 mm shorter when it's compressed. Normal kit you buy lower the car between 30 to 45 mm, too much for me and you must have shorter shock absorbers too with that huge lowering of the car.
Here are two good links with information:
I boughty two spring pads long time ago to have as spares, but what did I bought ?
Now when I examine them in deeper detail I see that these have two knobs, it's the 9 mm thickness. Measured from the deepest part to the bottom. 1 knob is 5 mm thick, 3 knob is 13 mm thick and 4 knob is 17 mm thick. Now I must found what I have installed on the car today, have they mixed them earlier or are they of the same thickness but the springs a bit different stiff. Perfect for me is if I can lower the side that is higher by 10 mm, because the spring is atached in the middle of the arm a 5 mm pad shim maybe will be okay.
