Re: [MBZ] heavier 123 front springs
Yes and 32-250 gives the lengths and resistance values for a whole bunch of the springs. The problem is that Mercedes does not have all of them available any more. It might be possible to have an aftermarket spring company build you the springs once you figure out which ones you want.

Re: [MBZ] heavier 123 front springs
I thought his issue is the heavier engine, if so that is more sprung mass which will need additional damping. Length probably won’t matter much (!!!) but they would need to be sized to accommodate the bigger engine mass; hence, perhaps a “heavy duty” damper or something from another car --FT Sent from iPhone > On Jun 24, 2021, at 6:18 PM, dan penoff.com via Mercedes > wrote: > > They would.

Re: [MBZ] heavier 123 front springs
They would. However, the mass of the engine and car itself are unchanged in a stock setup. The stiffer or taller springs in these cases were meant to offset the poor or rough road surfaces. Shocks have nothing to do with ride height - they dampen the action of the spring as you suggest. And it’s not so much that they would be “heavier duty” necessarily, the damping rate is changed with different valving. In some cases they might be larger in diameter to accommodate a larger volume of hydraulic fluid to deal with the larger/heavier load, but ultimately it’s the damping rate that matters. We’ve all seen cars that had bad shocks if we realized it or not - they’re the ones that when they hit a bump or change in the road surface they “bounce” rather than the suspension absorbing the hit and the frequency of the amplitude of response is quite rapid. That is, they take a while to “settle down” after such an event. -D > On Jun 24, 2021, at 5:39 PM, Buggered Benzmail via Mercedes > wrote: > > Don’t the shocks kinda respond based on the mass that’s pushing them around? > So a heavier engine == “heavier duty” shocks? > > I’m trying to remember my classes in dynamics... > > --FT > Sent from iPhone > >> On Jun 24, 2021, at 5:23 PM, dan penoff.com via Mercedes >> wrote: >> >> Shocks typically remain the same, as suspension travel doesn’t change, just >> the spring rate. >> >> I’m not sure if it’s the same for a W123, but for the earlier models there >> was a formula you had to employ that took all of the various options on the >> car and drive train to calculate which springs were the proper ones for the >> application.

Re: [MBZ] heavier 123 front springs
Shocks typically remain the same, as suspension travel doesn’t change, just the spring rate. I’m not sure if it’s the same for a W123, but for the earlier models there was a formula you had to employ that took all of the various options on the car and drive train to calculate which springs were the proper ones for the application.

Re: [MBZ] heavier 123 front springs
You can probably identify and possibly get stiffer or taller springs from Mercedes. Give me the VIN and I’ll look in the EPC to see what optional springs were available for it. Mercedes offered different springs for various models to accommodate road surfaces/conditions in different parts of the world.

[MBZ] heavier 123 front springs
I decided to drive the 123 wagon with the motor swap. It is pretty great. I put the cat back on to pass CARB. It is a euro wagon, so if it were not motor swapped, there would be no way to license it here in CA, lacking as it does a federal emissions sticker. With a 2006 motor it can be done, as long as it conforms to stock tune and emissions specs for 2006. Which it now does. Adding the cat back cost some performance for sure. But it also made the car far less stinky to drive. It now drives like any modern car, except more torque. The exhaust gas recirculation seems very loud also when it is on, which seems to be mostly when the car is cold for some reason. I think it shuts the VNT vanes down tight to raise the EGP and shunt the exhaust back through a cooler to the intake when the cat is cold. Anyway, the front springs are a little light for the om648. The car is not super low, but the suspension doesn't have enough travel up front, and oil pan will hit a concrete parking stop if I drive up too close. I was thinking of trying some 126 front springs. Anyone know if they are any stiffer?
