I did change my rear springs to non-AHC used LC100 springs many years ago.
The reason was that the car dropped to low with a loaded car and camper trailer. With these springs never had an issue anymore.
That's the LX450D over here I guess.
I drive mine for the last 10 years.
I ordered parts on Partsouq on the 21st, delivered today 28th.
Pretty happy with that.
Amayama was delivery estimated at end May.
