Need spring rating for rear

[coug66]

I put a Hyperpro progresive springs on both front and back of my K1200LT and now I am noticing that I am bottoming out in the rear.

I am not a fan of progressive springs since my weight is 360 lbs and most of the spring isn't working for me.

What constant rate spring weight would you recomend?

The shock upgrade was amazing on my FZ1. I used a Hyperco. I used a 700lb up from a stock 450lb.

Thanks for your help.
