Suspension lift?

[Mr_Groundhog]

I love the IS300h ...however, the one thing I'd change is the height of the rear suspension: seems a bit too low in the back?
Sometimes I think it makes it looks less sturdy (and a bit as if it already had two people in the back)
.... so I was wondering if anybody would know of a simple way to lift the rear just two or three centimetres? No more than that, really....
I don't even know if that would void the warranty (probably would hence not worth it?). The aerodynamics should not change much by such small change, but maybe it's just me looking at the car for too long. 🤪
May end up being too expensive to do, for what it is.

If you want it to hand like a boat by all means go ahead.  You probably need springs with more clearance, its the weight of the Battery in the boot what makes it looks like it's low.  Keep in mind the suspension was developed by Lexus testing real world terrain & dynamics of the ride changing it could well alter the way it rides & forget about mentioning insurance any excuse not to pay out.
