Hey Lads,
I was wondering, is there a specific formula I could use to determine what kind of rates I would need for the springs as well as the compression & rebound rates for the shocks?

While the A15 isn't that much heavier, I'm somewhat worried about the idea of a B140's entire drivetrain being heavier.

Also, she rolls a bit too much in turns around our mountain pass. I realize it might be that the suspension is 40 years old...Still, I can't have my brother or father getting in with me without the the GX begging for mercy.

Last time I went bonkers and way too stiff, so I won't be lazy this time. Show me the math
