GVM UPGRADE FOR LC300 SERIES GR-SPORT

[niftus]

Hi, has anyone out there been able to get a GVM upgrade for the GR-Sport variant that retains AVS functionality? I have been told that some providers have come up with a combination of products that makes this possible but haven't been able to find out who/where this has been done. Appreciate feedback from anyone that has gone down this route. Cheers.

I have a GR-S with a JMACX 4200 GVM - the key component to answer your question is the electronic version of the alpha dampers.

its a bit of a double edged sword - the drive mode wheel now only controls throttle response and transmission/streering gremlins, as the Toyota dampers are gone, however the replacement supersedes function quite nicely.

You get a cute little panel that can  operate the shocks in different ways. You can set your baseline firmness for each shock, and either lock this in ORRRR turn it to adaptive mode and feel the outside dampers firm up around corners, front ones firm whilst braking etc. It presumably uses a 2-axis accelerometer to tell which corner to do what. You can even get to display the data it’s utilising to make the realtime changes.

so… this seems to work like the Toyota system - in my opinion, it feels less ponderous than the factory suspension, but the relatively inconsequential issue of the drive mode not controlling the shocks can trigger the OCD amongst us.

I’ve only had OME suspension prior to JMACX - I must say I’m overwhelmed with how much engineering has gone into the system. Driving the vehicle around, it feels like it’s dominating the road, rather than timidly subbing. Coming from a 200 that felt like

As mine is black with an ARB bar and BFG 35’s, it’s also somewhat intimidating - which has its advantages at the school drop off - and its disadvantages as I’m pretty sure most drivers just think I’m another obnoxious black monster truck driver with a loud snorkel and exhaust.

im actually not that obnoxious.

have I even answered your question?

I know of no system that fully integrates that knob.

oliver - very tired
