  1. Hey guys,

    I have top issues as well. I haven't checked for any codes, but my top (pump) has completely stopped working. Mine is also a 2000 cab. So I figure something busted. I just can't find it. I had a leak somewhere, and added fluid every couple of months, but it got worse, and there is no pressure. The clam shell opens & the top unlatches in front. And the windows roll down. After that I have to lower the top manually, and there is zero resistance. once lowered, the shell closes & all is well. To close it the same thing happens. no hydraulic resistance, and I can't find the leak. Any ideas?

  2. Since this got resurrrected, I'll just point out that these readings are with new tires at recommended inflation. Worn tires alone will vary this up to 18mm LESS (7/10s of an inch), plus all tires from different makers are NOT the same diameter, even for the same size. This is just one minor spec of the "N" rated vs non-"N" rated tire specs. It is hard to correctly calculate what the height should be, as you can't just add tire wear, because the tire flattens. It is probably closer to .75 of tire wear.In addition, it is a grave misnomer to conclude that PSS9's are the same type height "adjustable" as true adjustables like JICs or Motons. This is not true at all. There is a strict allowable range set by Bilstein, if you want the strut to perform as designed. Many have called the PSS9s junk because they were trying to force the strut to perform outside it's recommended range, simply because it is possible to adjust the spring to that location. They are a great improvement over stock, within the limits prescribed by Bilstein, which is one of the reasons they are so much less than Moton or JIC. SO the charts above are of very limited FYI use when installing PSS9s...you CAN"T just choose the height you want to ride at, you can only choose "a little higher in the Bilsein range or a little lower". The installation instructions are crystal clear on this. There is only a 5mm range of adjustment for the rears, you start about 30mm lower than stock and can only go down to about 35mm, in the front. The start point is car dependent. Remember Porsches spec for the springs is + or - 10mm!!. If your car runs naturally higher due to spring tolerance, then you may find it 35 or 40mm lower to start. If your car runs lower, then it will lower less, as you are replacing the inconsistent stock springs with the consistent Bilstein ones. The 5mm is primarily for corner balancing, not for ride height. While the fronts start about 30mm lower and allow adjustment of 20mm lower from there, the rear hasn't that range, and sort of deyermines wher he fronts will end up. According to the PSS9 "expert" at Bilstein I spoke with, this is to allow adjustment for different front spoiler heights, rake, and corner balancing. The fronts require more height adjustment to "move" the same weight frontward or rearward, than the rears, due to the heavy rear bias on the 911. They are designed to be installed near the center of each range. I had called them because I thought it odd that the fronts had 20mm adjustment vs the 5mm in the rear. The rear height is more critical due to the rear engine RWD design of the 911, and the PSS9 is designed to be in it's best range when installed accordingly. They make 1.5mm thick spring isolator "kits" (read big fat blue plastic washers) that allow you to add a little height if need be, and fix the spring windup clunk that sometimes occurs on the front struts in slow turns.My $0.02.

    . Where are you getting tires with tread that's 1" deep? Sport tires usually have tread depths of 10/32" when new.
