I added a 10mm spacer to each spring at the rear axle. Intent is to add a bit more support to the AHC system, as I tow a heavy 27' Airstream travel trailer. This exact same mod could be done to an LC too, but will result in lifting ~1/2".
While the LX570 never asked for it, this is a well established mod carried over from the 100-series LX470. I had added spacers to my LX470, to bring AHC neutral calibration pressure back to stock and to support more load as I towed with that car also.
I'm not being as thorough here as I could hookup techstream to see where the pressures are. Note there is some mixed info in that the LX570 doesn't report pressures like the LX470 did.
The LX570 AHC seems far more robust. Where the LX470, once near payload capacity, will no longer lift to high position without additional mods like this, I've not found that upper limit on the LX570 yet.
Specifics: Old Man Emu 80/100/200 10mm coil spacers
I installed the spacer between the chassis and coil seat. Traditionally, I'd install this between the seat and spring. But this was easier as the seat fit tightly in the spring. The chassis has a depression that it positively locate the spacer anyhow. It's a quick 30minute mod. Need spring compressors.
