I just changed my front spring cups from a #4 to a #1 which seemed to lower the car about 1/2 inch. Since the car originally came with a #4 in the front, does this mean the rear will have a #4 as well?

I want to make sure before I go and guy the rears.

Thanks

The rears may not have the same as the front. You won't know until you take the springs out.

If I'm not mistaken it might a 3.from what I've seen the front is 1 number higher then the rear.show pics please when ur done.did u just change the spring pads or did u change the springs also.

Cars can have different spring pad/cup setup. If you give me your VIN, I can check your current setup. You can also go to EPC to check it out.

Most MB have diff pads front and back. these pads were designed to set the final ride hight of the vehicle. You can tell what size they are by looking at the "bumps" sticking down on the pads. 1 is level 1 2 is 2 and so on

Pads could be the same front and back, but not necessarily. In my case, I had 3's all the way around. I have a 320 cabrio fwiw.

Honestly, the pads are dirt cheap (like $4 on parts.com) so I would just go ahead and buy them. I'm in the process of trying to run zero pads all the way around but may want to revert to 1's if I'm having noise problems, so I'm just buying 1's F&R just in case. Never hurts to have extras laying around if you want to play with the height more.

I found out about my car setup from EPC. Apparently when I look up dlbehrns's car, EPC does not specify the spring pad setup. Perhaps the setup is only applicable to AMG cars.

Again ALL cars have a diff setup. it is based on acc and options. the factory only uses thes to set the final ride hight. the difference between the pads is very small you wont get much of a drop even from goging 4 to 1 bump. If you have a real intrest in the subject there is a neat thread on the 190rev site. I know it is a diff car but the idea is the same.

dlbehrns

the difference from #1 pad to #5 is .67inches.

insame1

that is the difference in the thickness of the pad. that height will translate to less of a difference at the wheel do to the angle and length of the LCA.

dlbehrns

what I was saying is that: there are 5 pads total, each with a different thickness. thinnest being #1 and thickest being #5. If you have a 5 and drop to a 1, I believe the drop will be about .67" or around a little over 1/2 inch.

No, I did not change the springs reason being my driveway is high and I do not want to rip my new front bumper apart which is why I opted to change the spring cups.

The back seems really high compared to the front therefore Im going to have to change the rears also. I may just go with a #2 in the back to have the correct stance. Im thinking if I put a #1 in the back as well the car may look a little odd as far as the drop goes. I currently have the stock rims and am thinking of getting some 18's.
