I am looking for a way to bring the rear up a little bit on my M2 as well as replace the rear spring. I dont care about original, stock, I just want it to happen. Advice?

One inch change in length will equal about 3 inches in height.
You want a slightly SHORTER shock.
Easiest way may be to slightly shorten the spring. Might need new shock rods, for open shocks, to get the preload back to what it should be.
Stock can shock? Believe they are held together like the original RS1200 Works shock. At the back of the shock there is a wire just inside the cylinder holding the plate which holds the spring inside the cylinder. Need to compress the shock by pushing against this plate and the front shock mount, or the front of the cylinder. As the plate moves inward, the wire ring will expose itself. Take out that wire ring, release the compression, then take out the spring.

Penske shocks were adjustable with about a one inch range and were slightly but noticeably shorter than stock.

You could technically use a 14" shock with a 16" shock mount, but if the 1:3 ratio mentioned above is the case, that's probably a big more height than you're looking for. You could always take your front shock mount to a machine shop and have them make a new mount that'll keep your current shock and raise up the rear to any height you want.

We moved the shock mount on the bracket lo slightly lower my S2. It's a bit easier with the early welded mount , but a good machinist / welder should be able to do this for you.
