There's another way to lift up the rear suspension of the evo chassis. You can cut off some plastic off the rear knuckles.
Once you got that area cut off, put everything together and install the upper suspenions top plate from the RS racing suspension tuning upgrade, then you can get the rear end of your evo chassis as high and as much clearance as a stock xmods truck. Here's a few pics of my rally STi from a few years back.
