He has a 2015 R/t 5.7 and wants to stiffen the rear end, anybody know of stiffer springs short of replacing with coil overs? Thanks for any help I did a search but only come up with lower springs sets
He is looking at stiffer rear for drag racing and he knows about the sway bar, but I can't find any stiffer springs for him unless they are lower and not after market unless a coil over setup.
I would guess that Hellcat springs would be the stiffest since that car has the highest weight rating. You can grab a VIN off cars.com and use that get the springs at dealer.
The Demon I think uses a softer rear spring for more weight transfer at launch.
