Rears are adjustable as per the directions. Provided yours did not come with any or you can't read words that don't glow, here it is:

Rear koni adjustment works best with a solidly mounted vice.

Lock end of piston in vice

Fully compress the shock (and I mean fully compress it)

While fully compressed rotation of the shock body adjusts the damping (rebound only). Clockwise is firm, CC is softer IIRC.

The shock must remained fully compressed while it is turned or the shock will not be adjusted. You should be able to feel when it engages/ disengages.

There is a huge difference between soft and firm so have no fear of being able to tell if it's been adjusted. On soft it should decompress easier than it compressed. On full stiff it's going to take a while.

Just like the fronts with the magin Koni knob, adjustment is 2 full turns lock to lock. The easiest way to determine the setting is to turn all the way to lock and count the turns made from full soft or full stiff.

Now the little plastic disc should be places over the piston and sits on top of the damper body. I'm pretty sure it's job is to keep the piston from being compressed enough to enable an adjustment change, though changing it requires some pretty serious intent that I highly doubt these could be adjusted "accidentally." The collar/ spring perch from the stock shocks must be transfered to the koni's and the rest of the spring and mount rebuilt and installed in the same manner as the stock setup.



The same weekend I replaced my suspension with the whiteline works kit (along with uiuc240) my friend recieved the Illuminas for his 510. Comparing them, the compression setting of the konis was right around 3/5 on the illumina's. The full soft rebound setting on the koni's was softer than 1/5 on the tokikos and full stiff was stiffer than 5/5. Of course this doesn't account for valving differences (if any) for the differeing applications (240 vs 510).
