Considering a suspension combo with stock springs and lowering springs..opinions?

[8thLS6]

Basically picture my stock rear height with my current lowered front height. I'm on gr-2s all the way arouns but one of my rears blew. So I'm considering stock springs with 1 oem strut and the 1 remaining gr-2 for the rear...and leaving the front dropped as is and get agx's for just the front come tax time. If I can keep the front gr-2s alive until then lol.
I should also add as is my rear sits slightly lower than my front..I think this combo would help even it out or at most end up with a slight rake

Also one other question. I have the common v6 axle vibe from lowering. Since agx's supposedly raise height some, could that possibly help with the vibes. Would new bump stops help any too? I already have to replace a motor mount soon, so I'm wondering if that will aid as well?

Thanks for any input
