Thanks for the input guys..

Going to try to talk to Rich again about the actual drop now that have heard good input from that regard;
and bio.. he has said they are progressive rate, though the same numbers have been given..
and again, a FULL set, front and rear.

We are going to need to get a 25% deposit going to get serious, money talks.
I am hoping I can convince roy/whunter to help me out with helping facilitate the monies on this buy, Phil didn't bite on the idea;
would rather not deal with all these financials. please lend any ideas, it needs to be generated as a group transaction.
If you are interested though email me at vogtland123@hotmail.com so I can generate good numbers. thanks.

Another Update!


We can make this a 40/30 mm drop kit, no problem. The 50 mm drop kit is pretty typical in Germany because the car has such a big fender gap. The main issue is that with many of these cars having old springs and the cars possibly sitting lower than when they left the factory. Therefore, you'll have to let them know that the drop is nominal and some may get less and others more. We will not guarantee ride height as is normal for our products unless it is excessive like 10 - 12 mm beyond nominal.

The original designs do not call for a progressive design. We speced it out as linear. These rates are ideal for a performance street application. Most of our Benz applications are linear because of the suspension geometry. The high motion ratio in a SLA suspension does not lend itself to a progressive spring design because the spring moves very little relative to the wheel unlike a strut suspension. Neither of the performance German spring companies ever offered progressive rate springs for that application, so I am not sure why they are asking for it. We might consider it for a 300TE as a rear cargo coil, but most had self leveling anyway.

I am trying out if I can get access to the original factory replacement springs for that vehicle. We produce replacement springs for the original supplier to MB. Do you think there is an opportunity to sell original replacement springs as well. See what feedback you get. I do not have any pricing yet, but I do not think they will be too high.


These are the final specs unless the is any additional input, thanks.

Thumbs up

Interesting about the constant rate...the link I posted to the AMG catalog also looks like they were using constant rate springs back in the day

40/30mm F/R drop sounds good. From Vogtland's comments about our older springs possibly already sagging, I don't think we should go with any less drop than 40/30. Available spring pads will help us adjust our own configuration.

Like said in rudolfgreen's post, the revised 40/30 is the final spec unless someone else has input. Reviewing my current spring pads and my adjustability options (2 nubs front/1 nub rear), I can go with the first proposed 50/40 or with the 40/30. Does anyone have opinions?

I don't know much about alignment, and I am not at all sure where I would take it around here for the alignment(except not the dealer). Would more drop be harder, more expensive, to get everything in full alignment after the spring change? Is more drop not better or could we run into alignment/clearance problems?

hear ya don, after all the input though, 40front/30rear seems better to fit the majority.
50mm drop would definitely perform and look better.. but concerned about street durability, potential shock/alignment difficulty,
and fitting 18"s underneath.... but really about the first two.

Don, what thickness spring pads do you have right now? I have the 2nd to thinnest of the four available in front and can go down another ~8mm if I need, but I'm maxed in the rear with the thinnest already installed.

Check this thread out for spring pad info & p/n...

8mm is ride height change in front going from 13mm to 8mm shims (5mm change at the shim on top the spring)...a little lever action there Also, I forgot there are 4 thicknesses available up front, 3 rear.

You can buy all three sizes for the rear on the forum parts link, but none for the fronts. I talked with Glauser Mercedes here in town a while back and they can get them for $10-15/pc, IIRC.

Talking Suspension Adjustments

I looked in my FSM last night and found reference to chapter 40-320 for front end alignment and 40-330 for rear end alignment. Those are nowhere to be found on the 123 manual, but I did find them on the 126 manual The suspensions between these two chassis are very similar, if not identical for the early model 126s. What I did find though, is camber, caster, and toe is adjustable for the front. The rear only mentioned procedures for toe, but it reads that camber is also affected by toe adjustments.

Toe and caster up front are adjusted by changing tie rod and guide rod lengths (threaded ends). Camber up front is adjusted by changing the position of the eccentric bolt at the lower-inner control arm bushing (it is standard equipment) - doesn't sound too hard. Toe (& camber) in rear is adjusted "after a wreck" by replacing standard trailing arm bushings with eccentric ones and lining them up correctly - hmmm, I wonder what the alignment shop would tell me if I asked them to adjust my rear suspension

Good info. How much will the ride change with these springs? Similar to stock or much harsher?

Update

Sent out the first round of invoices for the Vogtland Spring group buy.
It is for a $75 deposit towards the $250 total (incl s&h) via Paypal.
($202 for the springs, and the remainder to cover s&h and paypal fees)

If you are interested, please send an email to vogtland123@hotmail.com
would like to get the group deposit to Vogtland by the 15th.

and BG, from talking with Vogtland, believe these will be slightly stiffer,
similar to stepping from Bilstein Comforts to HDs, and should match well with these.
..and am personally a super fan in the performance of HD's
