The Coupe's spring rates are 451 lb./in. in the front and 480 lb./in. in the rear, while the Roadster's are 434 lb./in. in the front and 451 lb./in. in the rear, compared to 303 lb./in. front and 337 lb./in. rear on the base Crossfire Coupe and Roadster models.
One mod that is painless (1/2 day) is to swap out the sway bar bushings. Another is to go to 18" rims all around the extra sidewall in the back makes a world of difference.
I installed a Eibach Pro Spring Kit on mine this past weekend and I ain't ever seen so many bars & links connected to an inner hub. And BTW, the rear of the car only dropped maybe 1/4", front dropped 1".
