Keep in mind the OE spacer sits above the shock/spring assembly. This means it moves the whole shock travel down in relation to the arm swing arc, it does not extend it. At some point you’ll run out of downtravel in the suspension arm and cv before the shock reaches full extension, and more harmful, you can run out of shock uptravel before the arm hits its bump stops, which are what was designed to take this force, not the shock.
Plus you’ll eventually run out of length on the upper shock bolts which go through the spacer.
TLDR version: if you want more than the OE spacer lift on your brand new $80k+ vehicle you should go about it the correct way and buy a spring/shock package designed to operate in that range.
