I'd suggest installing an Airlift
×kit. Air suspension will seem like a bad idea at first since it's expensive to install and repair. However it really makes up for that with its versatility. It allows you the option to change ride hight, stiffness and softness with the push of a button. You can lift your Rav4 to overcome rough roads and lower it to minimise body roll when driving through sharp corners by dropping the centre of gravity.
