Looking for new rear leaf springs
I don't think I'd run that much spring rate. That's on par with the heaviest SS springs. From a handling perspective, you'll almost certainly be in oversteer. And they will likely raise the back end of the car.
If you like a firm, solid ride, increase the size of the torsion bars up front and go with a good shock like Bilsteins or the Hotchkis Fox shocks. Go with the 20230 springs, that will put the rate at 142, but with the slightly lower arch you should still sit at stock ride height, or maybe just a little lower.
With 1.12" torsion bars up front on my car and the 121 lb springs out back things are surprisingly pretty well matched, the rear sway bar is still adjusted at its lowest setting. And the ride is pretty firm. :D
The 20231M's sit with almost zero arch on my Duster. That's probably a little lower than stock from the factory, but its pretty close to where you usually see most cars with sagged stock springs sitting now.
This is how its sitting at the moment. The top of the front wheel arch is at 25", the rear arch is just over 26". The rear tires are spec'd at 26.1" tall, they're a little shorter as they sit. So it does have a small rake front to back, but it's fairly minimal. End goal is to lower the front another 1/4", and the back about a 1/2" when I install spring sliders in the rear and use them to set the height a bit lower.
