Just so everyone knows, I wasnt trying to defend or defame anyone. Just maybe offer a diff. perspective is all.

Dave, with them it's just the communication issue on some faulty parts.. it's not like they're collecting money and not giving any effort at all, but as you can see from this thread they got themselves involved in a mod that they didn't research enough and now haven't made this right in over 2 months since this was first posted..
they said that Koni says to cut at 52mm in one of his responses on page 1 of this thread.
When Koni says to cut a "Sentra strut housing" at 52 mm to install the inserts... they are talking about the OE strut housing of a Nissan Sentra SE-R Spec V - not a B13; this is where it becomes a "custom" job.
Overkill used those instructions from a Koni Spec V insert on a B13 rear strut housing.
They struts are called "CSK's" for a reason: CUSTOM shortened Koni's.. you have to do your own measuring because the differences between the B15 strut housing and the B13 strut housing..
If you drive a Spec V and want Koni Inserts, cut at 52mm.. if you drive a B13 SE-R, you need a custom fabrication - the instructions Koni supplies with the Spec V inserts DO NOT WORK. You have to take your own measurements and figure out the right amount to cut off to make the strut work right.
They didn't do this.... they used Koni instructions written for a B15 housings used w/B15 inserts on something that should have been custom: B13 housing w/B15 inserts...
And it gets better, Steve Foltz says in his writeup that you cannot use OE diameter springs with B13 rear housings and B15 inserts.. I don't know why exactly, but according to 98sr20ve (Steve Foltz) you can't.
Here is where he is saying the Spec V inserts can't be used with lowering springs (bolded in black letters):

Standard Koni B13 rears- This is your only option for those running lowering springs (such as Hyperco and Road Magnet) on a B13. You can not use any other Koni in the back on a B13 with those lowering springs. It is 1 inch shorter then oem standard so you don’t even need to do any tricks to lower the things. Just install them as the instructions say. They work fine with lowering springs but I don’t pair them with the Maxima fronts. Max spring rate is in the 275# range. Another option for those with lowering spring is to just use AGX's in the back with Koni in the front. The front is the place that we have major travel issue, the rear is not as big of a deal. With a under 1 inch drop you are fine in the back with AGX's with Hyperco. I have no experiance with Road Magnet springs.
B14 Koni Fronts installed into OEM B13 rear housings- This is what I pair with the Maxima fronts on a B13. This unit is strong and will easily handle your 400# plus rears. It is not externally adjustable. It require a really long bolt (grade 8) a bunch of spacers and it has to be spaced up to be the right height in the back for the GC setups. It can not be used with lowering springs. I struggle with recommending this setup as you need to install these properly or you can really have some issues. Max spring rate is in the 400+ range.
Spec V fronts installed in OEM B13 rear housings- Same info as above. Just externally adjustable and not as strong as the B14 front. Max spring rate is same as front. Around 400#.
B13 Issues in the back.
If you are running the OEM rear bar you need to use the OEM rear housing to have the swaybar mount. Not all housings have the rear swaybar mount but many do. If you use the oem housing and later run the progress bar you may run into clearance issues. The bolt on the bottom of the Koni may hit the bar. You can usually adjust the bar to solve this issue. If you are using the Progress bar already just skip the OEM rear housings and run some front housings in the back. They have a lot of clearance for the swaybar and don’t require as many hops to get the Spec V and B14 inserts to run at the right length because the housing places the bottom of the insert higher from the start.
