W124 Gullideckel wheels

[c107]

In comparing some wheels I had on my car, I learned something today.

The early W124s (until 1989) had forged wheels, same as the W126 and R107. Most of these were 6.5x15 ET48. Sportline are 7" and some base models were 6". Part 124 400 1802.

Then, in 1989, they cheapened them, and went to cast wheels. Part 124 401 0802.

Later cast wheels on the left, forged on the right.

Was it the pursuit of a lighter sprung weight that was the cause of the change or the desire to cut costs? Is there a weight difference? Is there s difference in strength?

That was what I had always understand. Forged wheels are stronger and lighter, but more expensive to make. Traditionally Mercedes always used forged alloys, like the ubiquitous Mexican hat alloys found on the 70s cars. the aftermarket wheels were generally cast.

And which method do they use on current model?

Presumably cast given how many MBCNSW members seem to bend on sydney potholes

Some years ago Lancia moved from forged to cast because the softer cast bend and saved the suspension components. I remember that now that you raise the issue of bent wheels. The ones on the Spirit are forged.
