Do you have divorced coilovers?

I'm sure some suspension guru will come and give a perfect answer but. Afaik. You can't do anything to the spring to change stiffness. You can adjust ride height and preload. Neither of which will change the stiffness of your spring.

You can buy stiffer springs tho.

In the video he shows raising ride height on divorced spring setup for bc coilover.

good video to explain how right height/preload don't affect stiffness

You can’t change the height just with the shock.

You can buy a different length spring with the same Or different rate, Swift makes all sorts of springs in different lengths and rates

Or

You can get the SPL adjustable midlink. I thought you already said you were gonna…?
The SPL mild link has a spring perch that has height adjustment. Just make sure you get the right diameter spring, I think it’s 65mm

From talking to SPL directly, a 6 inch spring is appropriate for almost every one

EDIT;
Look at the pictures

Preload will change ride height without changing the ride quality/stiffness and also without changing the shock body length. Which means you'll have the same suspension travel.

Whereas adjusting the shock mount will change the length of the shock and will change the wheels position at full compression and full droop.

With that in mind don't the divorced rear springs on a BC BR come with an adjustable perch? I think most divorced setups come with that. You can adjust that to adjust preload and subsequently ride height without changing the shock body length. I don't know what is an "acceptable" amount of preload but I assume if you are adding too much preload at some point you will need to extend the shock body length via the adjustable base. And possibly get longer springs like the guy in this thread below:


EDIT: Looks like they do come with adjustable perch?
