Stiff front end looking at aftermarket solutions

I’ve got my wife’s Challenger running 11s
I crawled all over a B/SA Challenger with a 440 six pack running mid 10s, bought there old springs that got the wheelie award at that NHRA event, I think it was averaging 110’ it didn’t get there by loosening the suspension.
Minimal suspension drop, and stiffening is what got the weight transfer.
