Anybody know what the spring rates are on these 2 cars or were I could find them?
Spring rates as in lbs/in? Never seen that published. They use different springs and pretty sure the T/A is stiffer. The SRT uses the R/T Super Track Pack springs in the front. Rear springs different too. The SRT can use a softer spring then stiffen it back up with the adjustable shocks. What you wanting to do?Anybody know what the spring rates are on these 2 cars or were I could find them?
Hellcat are 314 front and 777 rearI'm curious after reading this post. So, I decided to take a quick look and found the data. Granted, it's very old back in 2009.
The R/T Charger uses 204 lb/in front and and 514 lb/in rear with Nivomat rear shock.
The R/T Challenger uses 224 front 514 rear with Nivomat rear shock, 547 rear without nivomat.
The 300C SRT8 uses 227f, 622r.
The Charger and Magnum SRT8 use 284f, 778r.
The Challenger SRT8 uses 261f, 669r.
SRT8s sit 1/2" lower than the 5.7L and 3.5L rwd cars.
The cop car springs are 250f, 652 rear (with Nivomat), but sit even taller than base car due to how they are typically loaded down.
custom, based on each application and its intended purpose, in other words JJ Furillo from @ultperformancespeed would request additional information and then select the correct set up, springs rates, etc and would also set the coil overs based on the information, from there you have someone you can talk to to assist in adjustment based on driver inputs etcWhat is the spring rate of that sweet Jri set up if I might ask?
