Yep, 2011 Sienna AWD. Did 2” but others did 3.5”. Did it for higher H-point and just to f-around with it a bit out of curiosity. Also did modest wheel spacers. Now for kids to drive.
This won't affect the springs at all. They're installed above the tophat. Effectively it's only pushing the lower mount point down. As far as the shock knows it'll sit at the same "ride height" it was before, the spring will be compressed the same amount, etc. The control arms and CV will sit at different angles and lower. The geometry change could affect up and down travel limits...that would be a bigger potential issue, but only EVS knows how the geometry, motion ratios, and up/down travel limits may have changed with this. At least until some enterprising individual installs it and takes before/after measurements.
Enough is relative to what you want to do and how much margin/risk you want. In the Toyota community here in Colorado you can do probably 90% of the trails in the state with a 3-inch lift and 33 inch tires (over the 31 inch stock) along with whatever armor makes you comfortable. Doesn't stop some people from going further, but at least for the previous generation 4Runner and its platform-mates it took a ton of work and money to mod beyond that. I think the current generation can take bigger tires (maybe up to 35s) without modding beyond a 3" lift.
My rig before the R1T was a 3rd Gen 4Runner just like this — 3" lift with 33s. Felt comfortable on basically anything.
and I agree that spacer lifts are trash compared to the real deal! I also think folks should just wait for the non-performance trim for the same reason you mention.
Sorry gents, I will say it again - it's not coming and not happening. And it has zero to do with the active suspension, that is not the obstacle.
There is nothing fundamentally different about suspension in an EV than an ICE platform. Once you dump torque from the motor/drivetrain into an axle, it all behaves the same after that. Geometry is geometry and an EV drivetrain doesn't change that. Rivian may have made specific design decisions that affect what can be done on the cheap, but I have no doubt that if demand were high enough someone could make long-travel suspension work...it just may require replacing control arms and axles in addition to the damper/spring assemblies. That said, I highly doubt anyone will go through the hassle with both R1 already existing and the coming Scout vehicles that are both way more suited to off-road use than the R2 ever will be. That's like someone modding the hell out of a Bronco Sport instead of just buying a Bronco.
Okay, good luck with that, but it is not true.
