Haven't installed mine yet, but I bought the raising links from soupy's that are adjustable. The instructions say not to mess with the locking nuts as the two bars are matched at 1 inch more than stock ( which will apparently raise your license plate1.25 in off the ground). I'm going to install them when I bump up to a190/55 tire. And then if it's too much, start lowering the links and tune it to where it's perfect.
Not sure about putting my new chain on at the same time as I want the wheelbase shorter rather than long, and I think you have options for number of chain links depending on where you want the rear axle. As well, tuning with different link length will probably require chain tension adjustment. Totally doable, but I'm just not super clear on the dynamics yet.
The only downside is they're a little heavier than stock, so once I know my perfect raising link length, maybe have some made from billet. If an inch longer is perfect, then I will feel dumb for having bought the heavier adjusting links...
