fadiss2k: I assume you have the 5.9 Kit. I purchased the 2.9 kit about 3 months ago. I have put 2,500 miles on my kit. Since the day I put it in I have had a problem with the rear end shaking. I am not sure if it is the diff I purchased or if it could be the driveshaft or axles. I have an appoinment to have inline pro look at it on the 22nd of October. I was wondering if you might have experienced this problem with your kit. Let me know.

I get vibrations...but it is always the 6 blue bolts that hold the adapter flange to the end of the tranny coming loose. I have tried everything to fix that!!! Red loctite didnt even help. I even thought i was stupid and couldnt install that adapter(have changed my own motor/clutch/tranny/oem diff/axles/suspension/turbo install...pretty much do all my work on the car) so i took it to a shop and paid for a shop to install it the last time it came loose. Well few weeks later and it started coming loose again.
And now im having to replace my bearings all the time.I will agree that Inline Pro is top notch in customer service. Love there turbo kit as well. The parts they made for the diff kit(mounts) are top notch. But like the above guys...i wish i wasnt having this many problems though. Im in college so problems like this suck when this is your daily driven car.

If i know anything about inline pro they are doing the best that they can for you.
For those who complain about the price you need to look up the prices of the DSS parts because they are extremely expensive.

I hate to tell you guys this, but DSS has had a bad reputation for quality, fitment, and consistency for years. However, they always seem to be the go to guys for any differential, axle, or driveshaft projects. Many of the parts they ship out are excellent with no problems, but there are a lot which are simply wrong. Honda-Tech had lots of horror stories just like your own.
If I remember correctly, even Diff Techniques struggled with QC issues on their axles and driveshafts from DSS (for their own R200 conversion).

Not too surprised. If InlinePro doesn't want to be associated with that poor QC, they should do some internal control on the parts before shipping them out. After all, it is part of their branded "kit."
Either that or DSS should have access to a few Honda parts (like bearings) for test fitting.

Similar DSS bearing problems on 350Zs.

As a disclaimer, they have always been polite and pleasant when I've talked to DSS on the phone.

That is the best way anyone can put it. The Inline Pro brackets are nice pieces but, like you said the DSS parts are part of inline pro's diff kit. They should check the parts before they go out.
I am happy with my turbo kit and tune from them. All I want is to get this rear end vibration gone. I have had multiple built stock diffs. Ya I blew my stock with 4.77's but, my 4.57's had no problems at all.

I tend to avoid speaking up until all avenues have been exhausted, but it's time to chime in here. I had a set of DriveShaft Shop (DSS) 2.9 axles that caused vibration (esp. under load, almost like a bad CV). Trying to work out a fair resolution, but that's covered further down this post. Welcome additional posts from others who've had good or bad experience with DSS 2.9 setups, as I'm trying to determine whether there's an inherent design flaw and whether to go with the InlinePro 2.9 kit or to go PuddyMod. Timeline is below, car setup is in my signature (primarily a street car + autocross, rarely if ever drag-race style standing starts), and no one has called me hard on equipment. In fact, most people know I sacrifice 0.5 sec instead of downshifting or doing a hard launch so that I can preserve the equipment...
8/20/08 I ordered a DriveShaft Shop 2.9 kit sold by Lightning Motorsports for the stock S2000 diff. Installed 8/29/08 by JC AutoSpec, 2 weeks later. My job doesn't allow free time to either wrench or ferry a car to/from a mechanic while they're open -- so I was out of Lightning's 14-day return window before ever getting the parts on the car.
8/29/08 I paid $300 to get the DSS 2.9 axles installed (along with a reinforced S2000 diff) under the car. About 300 miles into break-in, I start to notice a very slight vibration, barely noticeable unless under load. Nowhere near boost though, since during the 500 mile no-boost / light load break-in I'm being ultra-careful. Around 500 miles, the rear end begins to "ring" and the vibes get worse under load (but no boost yet -- still breaking the diff in). Not cool IMHO.
9/26/08 After calling the diff shop and shipping the reinforced diff back (another $60 return of the diff, plus $45 to return the axles to DSS, plus $300 to swap the original diff & axles back in) the diff shop diagnoses like CSI. They find a one-in-a-million metallurgy flaw in the gears. OK, not the best of luck. No reason for any vibes though -- diff shop says the vibe had to have been a bad CV or improper shaft length. Argh. Despite that, the diff rebuilder I worked with offers either a refund of my money or to pay for re-installation of the fixed diff (they installed a new cryoed ring and pinion gear set so the diff was pristine in every other facet) and shipping back to me as good faith effort. I elect to take the refund (thought it was fate) and try the Nissan R200 approach.
I call up Chris at InlinePro who offers to broker a swap of my existing (possibly flawed) DSS 2.9 S2000 diff axle set in exchange for an InlinePro R200 setup. Awesome customer service and greatly appreciated. Two options presented at that time: full swap of the 2.9 kit if I elect to go 2.9, or an upgrade to the 5.9 kit for some extra money. 5.9's backordered, so I wait. A couple of weeks go by with InlinePro playing phone tag with DriveShaft Shop in some backordered parts needed to make a 5.9 kit. During this time, the NISMO LSD unit becomes forever backordered/unavailable so I have to get a Carbon diff instead. So Inline offers a discounted deal on the 5.9 Pro kit for all the hardship & waiting I've experienced so far (it's early October by now; car's missed a couple of races and the nice weather).
During this time, UPS beats the living hell out of a diff that InlinePro sourced for me -- both output flanges destroyed in transit. Good times. So I have to send that back (Inline or UPS covered the return shipping and new/safer boxing)
10/21/08 After giving up on the 5.9 kit ever becoming available again, I ask Inline to do the 2.9 swap they originally offered. They say DSS needs to confirm the axles aren't in bad shape before issuing credit. Umm, they were DEFECTIVE and the whole reason I'm doing all of this silliness. Couple of days pass w/no confirmation of refund/swap.
10/23/08 GOOD NEWS! My second R200 diff is here from Inline. No bent flanges.
BAD NEWS... the pinion is seized. Rut row. They say the third R200 diff is the charm, right??? Yikes.
10/24/08 I talk with InlinePro again and they say that DSS wouldn't honor the return/swap of 2.9 axles -- the defective ones they sent which caused the vibration in the first place. Huh? One axle was too long or had a bad CV, so one would think they'd offer to exchange the defective unit for a (hopefully) new, triple-checked 2.9 set tailored to the R200-diff-in-a-S2000-chassis InlinePro setup.
10/24/08 Called Lightning Motorsports (who sold me the DSS axles in the first place) after hearing of the potential DSS issue. I learn that I'm beyond their 14-day period, but they called DSS and at least got them to honor the original 2.9 for 2.9 swap agreement established with InlinePro -- swap the 2.9-S2000-diff-in-a-S2000 axles for a set of 2.9-R200-in-a-S2000 axles.
to Lightning Motorsports for helping stand behind their products. Mostly. When I ask whether they would consider refunding the axles less a restocking fee, well, not much love there. But at least they called and resolved my path to getting the original 2.9-S2000-diff-to-S2000-axle set swapped over to 2.9-R200-to-S2000-axle approach.
Almost feeling better... But a friend who works one row over from me overhears me talking with InlinePro and says he ALSO has a vibration problem with the DSS setup he installed in his GTO. And then I find this thread after searching for "problem" and "DSS" on this forum. Argh. While I'm already out $705 of labor/shipping (300+300+60+45) alone, here's my dilemma:
(A) Do I trust that DSS will triple-check their 2.9 axles, driveshaft, other parts and proceed down the path of a $4+K InlinePro, Carbonetics LSD, DSS 2.9 setup? Magic 8-ball says "Dude, you are gullible."
-or-
(B) Should I go back with my stock Honda axles, get something like a PuddyMod reinforced S2000 diff and be done with it?
Have to admit that after seeing more people have DSS-related problems (and my cube mate overhearing / commiserating today about his DSS-magic-fingers GTO kit) I'm very close to just going back to the stock S2000 axles and getting a reinforced (PuddyMod if I can afford it) diff solution. I'd feel way better if DSS was willing to guarantee labor and shipping if this now second set of DSS axles that I purchased turn out to be defective / cause vibration. Keep in mind that I'm hoping diff number 3 from Inline turns out to be the charm.
If any other folks have DSS-related problems and/or positive stories (Lord knows I need some good news to sway me in that direction), please share. I'm REEEEALLLLY trying to get comfortable with possibly going the InlinePro/DSS route, and the intent of this post is not to trash DSS. If this thread helps us S2000 folks identify a potential flaw in DSS's design which caused the vibrations and DSS fixes said flaw, my hope is that our good intentions spare future customers the same fate. Search my other posts and you'll see I'm not malicious & that I rarely say bad things about firms. I've had 100% satisfaction with Laskey, JC AutoSpec, Full-race, Laivins, CCW, Boost Logic, Summit, PuddyMod, Car-part, San Leandro Honda, Majestic Honda, SPC, etc. Some of these firms sponsor me, and their products and services are a big reason the car finishes toward the top of the podium in autocrosses (click these links for a couple of recent results).. That said, I don't want to be a beta tester when I'm dropping this kind of cash.
Best,
Stanford

i also have a good working stock diff to trade.
