All of the super stock springs have more arch than stock, and will make your car sit higher. I prefer a softer spring as the car will see a lot of street driving, so I picked a set close to the weight of the car. Still haven't had it on the road yet though.
i have the 3400pound springs on the Demon did pick it up a bit in the rear. and teh car sees street everyday it's able to nice ride smoother then what i was expecting. Used to drive around my popz 83 F250 3/4 ton truck that was lifted 4 inches the front were Disel coil's that where for the 3/4 and 1 ton trucks so talk about a stiff ride
