King Suspension Question - Front Coil over Spring Weight

[fastdiablo]

Hello, looking to find out if people are running 550lb, 600lb or 650lb front coilover springs on their 5th Gens. If you know and wouldn't mind letting me know, it would be very helpful. If you're running anything over standard 550lb, curious what kind of weight you have on the front like bumper, winch etc.
Thanks!
