Pretty difficult to lower one of them. The rear camber will be off. As for the air suspension, yes, you can reansfer it but there are many extra holes to be drilled and parts swapped, like the front and rear axles. The air pump and associated bits and pieces must be swapped as well.

What's the matter with the W109 that makes you want to dump it, other than rust that is?

Not part of the in-crowd since 1952. It's BRAKES not breaks. You break a bone, use brakes to stop your car. /rant

best way is to turn your hat round backwards and let the air out of the tyres. Mercedes spent alot of money designing that car. 2 hours with a grinder or cutting torch will not improve the ride.

despite the naysayers, you can cut the springs since they are liner. Also, you can swap over an air ride set up and get a controller from an aftermarket source (but spendy). I "believe" that you have to swap the front lower a-arms also, not exactly sure on that.

You can buy lowered springs from the SL news letter, but they are a grand. here is the link: Sport Springs I am still researching to see if I can fins another source. Don't worry about the folks who give you the"Mercedes built it perfect, why improve it" line. If that was true, why did they ever build another model?

Performance parts for w126, r/c107, w201, m117, m119, m102, m104 and few other things.

Reproduction 17" Penta wheels coming soon.

Thanks for the input John. I am about to rebuild the susupension anyway and wanted the car to have a better stance.

You could put some fat people in it ... har har..

I would replace the springs if you really want to do that - check with companies like H&R, Koni, etc, they probably make something for it.

as a side note i pulled up beside a late model A4. i though to my self "wow that thing is slammed" look at the passengers and all 4 were not under 350lbs.

i dare say the old 76' 300d might have won that drag race

they don't, although koni does make shocks to fit. better deal than buying Bilstien HD's, since there are no sports that fit.

your best bet for lowering springs would be to find a newer model car and see if the perches where they sit are the same, then get springs for that car. i was looking for springs for my 77 and 74 280 se and all the shop guys laughed at me cause the cars are so old they dont have them in their database, but i found a number of the newer models where the springs are an exact fit. DO NOT CUT YOUR SPRINGS AND DO NOT HEAT THEM to lower it. if you heat your springs it will lower them but the metal becomes brittle and could snap. if you cut them you decrease the load bearing capacity of the spring and your car will ride like crap and most likelybottom out when you hit bumps. go to some junkyards and and do a lot of research youll find what you need.
