W212 front coil spring OE vs kilen kyb Sachs

[kingkhan]

Hi guys
So i fitted some new aftermarket coil springs on my e250 cdi (4 blue dots on oe coils) with bilstein b4 struts. they are known to be comfort springs so the car sits higher than standard and sport. The distance between the tyre and front arch is 85mm.

Has anyone had problems with good branded aftermarket Springs?

I replaced them with KYB springs first, the car was sat very low and became extremely bouncy, felt like the coils were bottoming out and touching each other over speed bumps. I noticed the coil design being a little different from OE so i decided to remove and swap to Kilen 17295 (with comfort suspension). This improved slightly but the car was still sat low and the distance between the tyre and wing was 55mm. After 4months of driving with the kilen springs,i decided to refit my old springs and it feels normal again and the height is back to normal. I called Kilen and they said the springs should sit almost exactly like oem, so return them to the seller and they will have to warranty claim.

This is the kilen spring gap between coils

UPDATE- Kilen sent the springs back to the factory and they admitted that they had printed the wrong product code on the coil springs so they have refunded me. what are the chances of that happening!

I was going to say that the most likely issue with ill-fitting non-genuine springs, is incorrect cross-referencing of the P/Ns, rather than 'poor quality' of the non-genuine product.

I could not live with those comfort springs.......looks wise.....looks like a 4x4! Mine has 18 inch rims and factory sports suspension.....but I still think the rear sits a tad too high....
Not the best pics as I'm at work but it should give you an idea.
