I think I'll try out these Coil Springs
They're around 200 lb/in and should be somewhat comparable to the 919s I'm currently running. I'm planning to cut the coil springs down to the height and use the 2" poly spacer to help seat the coil to the frame.
I've also ordered material to build all 3 rear controls arms. Not only are mine bent, but I will need to adjust the rear pinion angle after the extra lift.
...That's about it for now. I currently have the front axle pulled for paint.
