WB Scat Packs have the highest spring rates of all the trims - there was an FCA media release in a Motor Trend article:


"Especially the Scat Pack Widebody.

"This started out as a project to just put the Widebody package on the Scat Pack, but then we thought, 'Why don't we try to go a bit further,'" explains SRT vehicle dynamics chief Erich Heuschele.
His team ended up with a completely new spring/damping/roll-stiffness setup. At 359 lb/in, these are the stiffest front springs on any Challenger, up from 313 on the Hellcats and 284 on the base Scat Pack.

Its rear springs are shared with the Hellcats. The anti-roll bars are stiffened by increasing their diameters from 32 to 34mm in front and from 19 to 22 in back relative to base Scat Packs.
These hollow bars are now the same diameter as the Hellcat's solid ones. New Bilstein three-mode adjustable shocks are borrowed from the Hellcats but are uniquely tuned to match this spring/bar setup, the weight of the lighter naturally aspirated engine, and to work with the big 305/35ZR20 Pirelli P Zero three-season (or P Zero Nero all-season) tires.

Note that by contrast, the Redeye Widebody is just a Widebody package on a Redeye with no fundamental tuning changes."
