Leith280zlt1 Posted January 5, 2009 Share Posted January 5, 2009 Hey guys. It's been a while since I've been very active on the forums. I'm about done with school now and I'd like to be more active in the Zcar community. I've decided to go ahead and start building differentials again. I'm not doing it for any profit really, maybe a bit of pocket change. What I can offer is the Power Brute limited slip unit in whatever gear ratio diff you want. It's about $600 for a new unit plus shipping. I've got several diffs at the shop now with various gear ratios. I know I've got a 3.54, 3.7 and 3.9 out there right now. I've also got a couple r180's. Don't know what gear ratios they are tho. The limited slip unit for the r180 is a bit cheaper but I'll have to call up Reider Racing to find out exactly how much it is. For the rebuild differential itself I charge $150. If you decide to send me your differential, I'll cut that down to $75. With the shipping both ways to anywhere in the Continental US it'll end up being about $750 to $800 total. I know it's expensive but so is the alternative. Finding a used LSD is very difficult and often you'll spend over $700 when you do find one, and then it's going to be a 3.7 gear ratio. You could order the unit on your own and install it yourself for about $650 with the shipping for the limited slip. It's really not that big of a deal to do the install. The benefit you get tho is that you get whatever gear ratio and *if* I run into problems with shimming or whatever, I have the capability to fix it. I'll also machine the bolt spacers for the ring gear when it's needed. So, if anyone is interested, I'm in Gainesville Tx if your wondering about shipping. If you have any questions about the quality of work I do you can ask some of the members in the forums for a recommendation. Let me know what you guys think and if you have any questions.

junglist Posted January 5, 2009 Share Posted January 5, 2009 How are you still able to source the Power Brute LSD units? I thought they were out of production? Am I mistaken? Quote Link to comment Share on other sites More sharing options...
Leith280zlt1 Posted January 5, 2009 Author Share Posted January 5, 2009 Well, here's the deal. Reider Racing is no longer in business. They shut their doors about a year ago. The company that bought them and all their inventory can still get those units but there is a minimum amount that they have to order. I'm already set up as a distributor. What I'm going to do is buy the minimum amount (10) to have them shipped from overseas. The only downside now is that I have to pay for the freight from overseas. I don't know yet what that will cost. I know I can get rid of 10, I'm not going to get any more than that at this time. We'll see how fast they go since no one else is selling them. I'll keep you guys posted. Quote Link to comment Share on other sites More sharing options...

I'll keep you guys posted. The story from former member "Mike" was that the factory in Japan burned down. Mike had tried to organize a group buy on these units and it ended up falling through. I wouldn't give up though, it could be that Mike handled the group buy so badly that they just gave him a line of BS to get rid of him.

Leith280zlt1 Posted January 5, 2009 Author Share Posted January 5, 2009 The guy I talked to said everything was a go right now. He told me the prices on the units themselves but didn't know about shipping. He sounded very optimistic and definitely sounded like he knew what he was talking about. I'm gonna keep with it and make sure everything is still fine, I'll let you know if anything changes tho. I've been getting quite a few calls about LSD's so I know people need 'em. The sales rep did say that it would be a minimum of 45 days before they were ready to be shipped. Keep your fingers crossed I guess. Quote Link to comment Share on other sites More sharing options...
blairjj Posted January 5, 2009 Share Posted January 5, 2009 I'm fairly certain that member savage42 (gary) checked into this and confirmed the story, at least the one that Reider was giving out. I'll see if I can find the thread. EDIT - found it: http://forums.hybridz.org/showpost.php?p=820201&postcount=360 Jay Quote Link to comment Share on other sites More sharing options...
johnc Posted January 5, 2009 Share Posted January 5, 2009 Since we've had these LSD group buys fall apart before, make sure you are truly able to deliver on this before asking for any money. Please do your research and perform a lot of due diligence on the vendor you're choosing to work with. Also, please make sure you are up to the communication and follow-up demands necessary to get this done and be ready to step up and and immediately fix problems when they come up. No excuses. Read the Rota wheel group buy thread to get an idea of the work you're committing yourself to. Quote Link to comment Share on other sites More sharing options...
Leith280zlt1 Posted January 5, 2009 Author Share Posted January 5, 2009 Of course I wouldn't ask for money before ordering these things. In the past I wouldn't even have people pay me directly. They would order the limited slip unit themselves and then have reider drop ship it to me for the install. So, I'll make sure I either have them in my hand or have a tracking number before taking orders. This time around, I've got the capital to buy the units myself before trying to make a sale. And like I said before, I'm really not trying to make money on this. It's just I see a lot of need for these things and it's a good way for me to contribute to the Zcar community and still make a little pocket change on the side for the installs. I hope this doesn't fall through this time around. I'm fairly confident everything's just fine. The main reason I quit doing this before was because it was just as easy for people to order them from reider racing and figure it out themselves as it was for them to go through me. I'll just have to play it out and see what happens. Edit: Also, I'd like everyone to keep this in mind. This is NOT my primary source of income by any means. I design and manufacture automotive machinery with my Father and this is completely on the side. I don't want people to get the wrong idea about this. I have the shop and resources to do a good job, but I'm not a customer service rep by any means. I'll do my best to keep this thing as professional as possible and I WILL make sure whoever I deal with is happy in the end. The only thing I can't promise is that there will be any sort of time line for getting one of these things out the door. At the very latest (once I actually have the LS units of course) it'll be a couple weeks before I can get one all cleaned up and shipped. I hope everyone is ok with that.

Guest kmat Posted January 5, 2009 Share Posted January 5, 2009 Sir do you have any new or used LS units for an R-180 at this time? If so please call me at (626) 358-1754 Regards, Ken Quote Link to comment Share on other sites More sharing options...
Leith280zlt1 Posted January 5, 2009 Author Share Posted January 5, 2009 This is the reply I recieved from the Sales executive concerning the factory being "destroyed". "Hi Larkin, Thanks so much for your help this afternoon. I'd like you to make sure everything is still ok in Japan. What I'm hearing from some of the customers is that the factory in Japan had problems during an earthquake last year an lost everything. They have told me that these units aren't available any more since the factory wasn't going to re-tool the factory for these units. Is that true? Apparently this is what a few people heard from Reider Racing last year. Thanks alot!" "From what I am hearing, there are no delays with any of the factories that we are using. I am being told that these are ready to be ordered and manufactured. Larkin Wood II lwood@omix-ada.com Sales Executive Omix-Ada, Inc."

Leith280zlt1 Posted January 5, 2009 Author Share Posted January 5, 2009 It looks like the same story on the R180's. If I have enough people ask about them I may try to order some. I didn't sell alot of them before when I was doing this so I'll probably start with the R200 units first. Quote Link to comment Share on other sites More sharing options...
mark Posted January 5, 2009 Share Posted January 5, 2009 I had Leith280zlt1 put this unit in my 3.36 R-200 a few years ago. Service was good and the unit has held up well to almost 2 years of track days. Quote Link to comment Share on other sites More sharing options...
stroked_Z Posted January 6, 2009 Share Posted January 6, 2009 what kind of horsepower will these handle Quote Link to comment Share on other sites More sharing options...
Leith280zlt1 Posted January 6, 2009 Author Share Posted January 6, 2009 I KNOW that they can handle up to 500 hp. From what I've read in the forums they have proven to handle up to 750 hp (yell at me if I'm wrong) but the halfshafts aren't strong enough. I think Modern Motorsports has a CV joint upgrade that solves that problem. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted January 6, 2009 Share Posted January 6, 2009 If you're basing that comment on the JNJ guys' wheelstand picture, they use a welded diff, not an LSD. The 300ZX diff has a bad rep for stripping the clutches above 300 hp and then functioning as an open diff, but they only had the one active clutch disk per side. I haven't heard numbers for the Power Brute LSD, but handling 500+ wouldn't surprise me at all. Quote Link to comment Share on other sites More sharing options...
takayuki Posted January 8, 2009 Share Posted January 8, 2009 are powerbrute lsd's 1 way? 2 way? or 1.5 way? I might be interested Quote Link to comment Share on other sites More sharing options...
Leith280zlt1 Posted January 8, 2009 Author Share Posted January 8, 2009 They are completely 2 way. Quote Link to comment Share on other sites More sharing options...
zx beast Posted January 29, 2009 Share Posted January 29, 2009 hey, I am in copperas cove tx, and lookin for some lsd... if I were to drive down there, how much would it cost to pick up a lsd... I have an 81 zx na... what is the best gear ratio??? Quote Link to comment Share on other sites More sharing options...
angry_dave24 Posted February 3, 2009 Share Posted February 3, 2009 Ok so i have a 1975 280z and i assume it has an r-200 diff, since what i have read on here is that the manual version had r-200 differentials. how much would it cost for you to rebuild this diff, with a lsd that will handle the power of an ls1. please call me at 910-308-0934 Quote Link to comment Share on other sites More sharing options...
bjhines Posted February 4, 2009 Share Posted February 4, 2009 ^^^ rebuilding the diff brings up the questions... Are the shims available? are the bearings still available? Or is this yet another part of the project that will require creative approaches. Quote Link to comment Share on other sites More sharing options...
