**FIXED** Ride is sitting way too high!!
**FIXED**
I checked for installation error but everything was fine then i measured my new shocks with the old oem ones and they were exactly the same. so i bought a set of C2 front springs off my friends e92 316i and installed them and finally my ride height is normal like all the e90s w/o zsp. Thank u all guys for yr help Hi guys, i just replaced my old shocks after 100,000km and they were completly worn out , i installed new Bilstein B4 for the front and the rears the part numbers are VNE-500 , VNE-501 & BNE-502 which are the direct replacment for my 320i, now the car sits way too high about 4 and half fingers in the front but nothing changed in the rear hight , i used to have a 3gap in the front after i installed 17 inch style 285 and with the stock 16s the gap was 2 and half fingers, i checked everything regarding the installation and everything seems fine. iam really annoyed as it reminds me with the x-drive version , i checked the springs codes and i found the front are C3 and the rear are C2, i also checked my friends 320s and they have the same springs but there height is completly different is this due to the high pressure of the bilsteins? or my front springs are wornout and cant hold the new shocks?? i also heard that people use the zsp and msport springs on the standard suspension but iam a little worried about the life span of my new shocks , and the only aftermarket springs i found was the koni sport springs that drops 30mm fornt and rear. Any ideas??

If you JUST replaced them the car might need to settle still.

Hmm...this is not good, as I was just preparing to buy some Bilstein B4s for my car. I checked the part numbers and they seem to be the right ones.
Gas pressure and damping force should not have anything to do with the ride height unless your car is sitting on the shock bump stops (search Google) - can you check ? If it's the case, the ride should be very stiff in front. In some applications, the stock bump stops have to be trimmed or replaced with shorter ones. Did you receive new bump stops with your new shocks or used the stock ones ? The other reason is that the replacement shock has the spring seat placed higher than the standard shock, which should be very unlikely unless you received different parts than the ones you asked for. Did you have the chance to compare the two shocks (Bilstein & stock) side by side to see if the placement of spring seats is the same ? At the rear there are no problems because the spring sits completely independently from the shock. By the way, how is the ride with the new shocks ? Let us know how this evolves...

About the spring perch i didn't compare it with the oem shock as the bilsteins were a direct replacement to my oem shock, but it seems that i will go to the shop i bought the shocks from and i will measure my old shock with a new bilstein set. My opinion on the bilsteins is that they dramatically improved the car , the difference is night and day , i dont feel that the rfts are stiff anymore and the car drives perfectly on poor roads exactly like the comfortable E60s with 16s !!! . On the Highway the handling is improved alot and the car is completly different than a brand new 2012 e90, i was going to buy SACHS aftermarket (Super touring) they are way better than the oem BUT Bilstein proved that they are the best stuts ever. I advice anyone using the oem setup with the crap oem Sachs to replace them with B4s.

Abcarino,
I think your model is considered as a standard model, so it may came with standard height springs (as you found out). According to your OP, the new shock has helped the springs to bring the car to its proper road height. I think regardless of make any replacement shocks may do the same thing. Plus, when you changed to the 17 inch wheels from the 16 inch wheels, you have increased the height by that 1 inch or so. As you have already researched, you can use lowering springs or spring perch drop units (usually used a the front) to get it back to the height you desire. This is your best bet. Changing the bump stop does absolutely nothing to lower the car except to increase wheel travel, which can be a good thing in certain circumstance. Good luck and keep us informed.

I think, maybe, the springs are soft and compliant (not sure what Egyptian roads are like). The shocks are new and freshly charged compared to worn shocks. Together, they may cause your car to sit a bit higher than norm. I agree with others that have mentioned the shocks will settle in time and mileage. Have you taken your car to a good mechanic or dealership (someone that you value their opinion) to have an evaluation performed?

first check that everything was installed correctly, make sure the front struts are completely seated in the spindle.
if that is correct, whoever did the install may have tightened everything while it was not at ride height, resulting in bushing bind and not allowing the suspension to settle. so if thats the case, loosen the bolts, set the suspension to ride height and tighten everything |

Yes, Kevin gives really good advice. abcarino, now that you've fixed the problem by installing C2 in front (), what do you think happened to cause the problem? Did the installer switch springs on you by mistake when they installed the shocks?

no my car came from the factory with c3 in front but it seems that the shocks were worn when i installed the 17" wheels so i didn't notice any change in the hight untill i installed my new shocks that stretched the springs back to its original position
