they will work on the SRT6 for sure, but be ready for a NASTY-rough ride. i had a KW variant coilover setup on my jaguar. handled like a go-cart, and felt like riding the rockies. very very uncomfortable, but functional.

the weirdest thing about this car is that when i lowered it with H&R springs and put in the Koni adjustable shocks, the ride got BETTER than stock!!!! i've NEVER had that happen with a car i've owned!

if you know your way around cars, the KW's will still take you quite a bit of time fabbing to make them fit right, but they will fit.
