Rear sag on acceleration in 4A

[Redrightthand]

I have a 2022 Wildtrak, upgraded to the Fox 2.5 Coilovers. I had it in 4 auto the other day and noticed a significant amount of sag on acceleration, switched to 2H and operates normally no sag. Sag is while rolling and on take off. Is this normal and if so what is the purpose?

4WD vs 2WD plus soft suspension.

It's cause the VTEC is kicking in.

I had this issue with my HOSS 3.0 Fox's... It's gone now with my ADS setup, but nearly as plush. The first thing I noticed and seems quicker off the line...!

its just due to the forces at play when you're turning all four wheels versus just the rears. the sasquatch rear suspension has a lot of anti-squat built in, which means when you apply power to the rear axle, the torque applied to the axle makes the suspension want to rise up. you may have noticed if you power brake in 2wd, the rear rises a few inches. when you are in 4wd, the front tires are pulling forward, which shifts weight rearward, causing squat. think about a worn out honda accord taking off from a light: brake release and the rear whacks down on the bumpstops because its a honda and by god, the oem shocks don't need replaced at 150k.

Basically, since torque is being split between the front and rear, theres less torque to the rear axle and less anti-squat, plus the torque applied to the front axle is shifting weight to the rear making it squat.
