I installed Koni Yellow with the H&R springs from Tire Rack. They are awesome, mine are set to medium and my chassis has come alive. I went to the track this last weekend and really enjoyed the feel. Next time I will adjust them to 3/4 firm for the track. Now that the track weekend is over I will adjust them to almost full soft.

 

Where on the shock do you adjust the Koni Yellow shocks?

 

On all four, you adjust the konis on the top. This top adjustable piece is accessible fairly easy for both the front and the back. There is an adjustment part that will stick out through the hole in the shock mount and the chassis. On the front, you have to remove the two plastic covers (on the left and right hand side of the battery cover), which is easily removed with one screw each side.

On the back, the mechanic showed me how easy it is to remove the carpet and adjust them. There is a small rectangle "shelf" that is behind the rear seats, you just grab the carpet in the middle and pull up, and then grab the ends and the carpet comes out very easily (you are not breaking any kind of glue or seal, so don't worry). Once the carpet is out, then you have access to the adjustment part for the rear dampers. The set comes with 4 white adjustment handles, and you just turn left or right depending on which adjustment you want to make. It probably takes under 5 min to get access to all 4 and start making your adjustments. Very pleased with how Porsche obviously thought about giving owners access to the shock mounts from the top, and then Koni designed a system to take advantage of that design. Fairly good process for a car that was built in 1999. Now days you just push a button, but for those who don't have a 991 this is a great approach, and also gives you more flexibility on the exact setting you want to select (which may be a good thing or bad thing depending on who is making the adjustment).

 

The only thing I didn't like about Koni adjusters at first is the lack of click adjustments or any markings but I got used to it.

 

Vikings8 - thanks for that. Looking at the pics i thought might be the case but had no idea how to actually access them to do that.

 

You could stick your own marking on with an indelible pen once you know which way to spin for soft hard and where you like them.

 

They go around multiple times so markings will still have to be accompanied by counting the turns.

 

If you have a Bose sub, you have to remove the bose faceplates (they pop off) and then unthread this painfully long torx (t27 I think?) bolt, slide the sub forward a bit, unplug it electrically, then slide it the rest of the way out.

This got to be such a pain that I now just leave the faceplates, bolts, and carpet squares all uninstalled. The sub won't go anywhere so long as the rear seats are up; the brackets hold it down and the seats keep it from sliding forward.

 

sds911 - Please keep us updated when you get them on your car and your thoughts on them - thanks.

 

Will do. Just paid my property taxes so shooting for summer to buy and get installed.
