It's not difficult and you only need to remove the wheel. I used my floor jack handle as a prybar (must be at least 3' long and not wooden) to lift the spring. I was able to slide handle through a coil of the spring and used a block of wood resting on the rotor to pry down against. This relieved the tension of the spring off of perch so I could move the ring down and lower the perch. I was able to do it my self but I highly recommend someone else help to hold the prybar while you lower the perch...much easier to do with two hands. Make sure the prybar is solidly planted because if it slips out and that spring comes whipping down it will be ugly. You only need to lift spring an 1/8" to get the job done. Here's a drawing of what I mean. Do at your own risk.
Bumping this one back up. Thanks to @eroc0808 for the advice on moving the rear spring perch. I attempted with all my might-but couldnt get the springs up high enough to move the perch on the drivers side. On the passenger side I was able to move the spring up enough and actually move the C Clip-however when I put the spring back down, the c clip did not sit in the perch properly. Thanks to my prybar-I scratched the rear shocks pretty good attempting to pry the springs up. To avoid further damage, as the car was already on stands, I decided to remove the drivers side rear shock assembly and compress the springs off the car to move the perch-problem solved! Now I just have to reinstall and do the passenger side.
Forgot to add a pic-looks like by moving it to the lowest perch setting I should lower the rear 1/2 inch or so.
With this in mind, the car could effectively be lowered a bit on the OEM springs if the car is equipped with PASM/SPASM, right? Are these adjustable perches on the 992 PASM shocks as well? If so, this might explain why I haven't seen any consistency in ride height among the 992's I've seen on dealer lots. Some without SPASM were lower/more even than cars with SPASM and I couldn't figure out why.
Just had my GTS lowered with KW HAS last week, drove it about 100 miles and then went back to lower the front a bit more. The car drove surprisingly well at first but today after lowering it just a 1/4" more up front is riding quite bouncy. I'm contemplating trying a DSC module or lifting it a 1/4" front and rear.
Did you manage to install the KW Has kit with Centre Lock OEM wheels without issue? The kits say "no centre lock wheels" but I've heard of some people install HAS without problems and using the Centre Locks. Thank you.
