i was looking at azautohas and they have 2 sizes for the rear, 9.5mm and 19mm, which ones should one get...if the springs HR will already lower the car 1.3, is the size of the spring what it would lower further?

is this synonymous with the nub

MB has three sizes available for the rears, one-nub, two-nub, and three-nub. IIRC, to get a proper stance is two-nubs in the front and one-nub shims in the back. Definitely not three-nubs in the back!

Oh - this is all for an SLS car. I don't have any experience (yet) with a non-SLS set of springs.

wait so is the number of nubs u have increase the height or lower the height

im so confused as to whether is the springs or the nubs that is controlling ride height..

i always thought that if u have springs that say they drop u whatever inches, thats your drop,

how does this all figure

and are these nubs something u have to uninstall the springs to change everytime u wanna see your set up and then have to redo alighnment etc

Yep, partially, yep. :)
Shims sit on top of the springs inside the spring perches. Factory stock is 4-nub F and 3-nub R (IIRC). The best looking H&R setup is 2-nubs F and 1-nub rear. But.... if you have a little rubbing problem, a shim change can help.

Changing the front ride height *requires* a wheel alignment so put in the new springs and shims, drive around the block to settle the suspension and make a decision on keeping that or changing it before heading for the alignment.

There will be opinions galore as to the "proper" spring pad setup. I have 2 nubs front and 3 rear on my 84 AMG SEL with lowering springs. See my previous posts for pics of my stance. My stance is very level.

I have 1 in the front and 3 in the rear which give it that raked looked. I like the look but will try a 2 in the rear just to see how it looks. If I don't like it I can raise it a bit with the SLS.

so......if i was only to change my stock front nub from 4 to 2, would i probably get the desired affect of a lowering, even if i kept the stock suspension set up

I cut 1.0 coils off the front springs in my SEL and it looks great. With the stock springs in there it rides noticeably softer than my SEC with the H&Rs. Back to the original question - whaddya want??

My SEL is nicer driving in the city with the bumpy roads, my SEC is MUCH better blasting through the mountains.

Yup, 8, 13, 18 and 23mm are the sizes 1 to four nubs. So you would lose about 10mm going from 4 nub to 2 nub. Are you sure you have 4 nub in the front? Mine was on 3 nub as standard i think.

ok cool, so nubs are spring pads/shims...good

very wierd pricing on that link above, the 13mm fronts are quite a bit more than the others

and theres even differnt sizes for the rears..

i think i might go conservative with my set up and go either 3 in front and 3 in rear so i guess that would be 18 mm and 19mm respectivly

I would vote for not going with the 3's. Especially in the front. Your thread started worrying that 1.3 lowering would not be enough. I don't know about your car though it very well may have 1's on the front and back. My SD did. If that were true than you would be only be lowering your car about an inch if you went with the 3's. I bet if you get 3's you will later want to change them. I have Eibach springs with 1's in front and 3's in back. If I get in there again I will change the back to 2's or 1's.
