2wd rear blazer coils HELP

[Nightmare70]

Hey guys I got a new project 70 blazer I lowered it with rear coils 4" CPP these were crap bottomed out on everything and bounced up and down. I switched to a 3" Western chassis these are WAY better support the blazer alot better no bouncing and squishiness, But with my two teen kids in it the blazer bottoms out. I know its the extra weight but I was wondering if there was something I could do to keep it low and still support the weight? Something other then bags? Thanks for any help
