all cleaned up up and ready for a race next weekend weather permitting. I’ll post video when I can.

Inspiring work. Very clean and functional work you’re doing.

Back on track with alignment done per HBZ sticky....... can’t wait to race again, get some tire temp, and do some fine tuning

terrible phone pics but a here’s a couple of shots.... I short test drive indicates a much smoother and quieter ride. Car goes in for performance alignment on the rear Thursday.

Well it finally all fits! Car is back together and waiting for a performance alignment with new TTT LCA's. It took DSS 4 attempts to get the stub axles machined to OEM spec but they finally got it done. Personally, I would use checkered flag racing if I did it again, but I will give Lee at DSS a lot of credit for contuniually working to find a fix. Hopefully DSS will now have the proper specs for future buyers to avoid all the hassles I went through. Jim

Hopefully DSS will now have the proper specs for future buyers to avoid all the hassles I went through. I owe the HBZ community an apology for using the forum to vent my frustrations..... I was never looking for technical "help", because the only fix had to come from DSS. Just more of a buyer beware that was a little more colorful than intended. Anyway, I appreciate all the input, and I hope others can avoid this expensive frustration in the future. Jim

Stub axles arrived today. Initial measurements look promising..... let’s hope the 4th attempt is right. I’ll try to find some time to install this weekend and update HBZ accordingly. Jim

Pics llave please....

The overall length to mounting surface is 14.25 full compressed and 16 fully extended. Axle bar is a black powder coat. They came preassembled 108 mm 930 “style”. FWIW I believe the oal length is going to be 1” to short..... per DSS instructions, once they return my wheel stub axles (hopefully with proper machining of all surfaces per OEM axle I sent them) I need to bolt up the stubs and take measurements so they can adjust the length of the axle bar as necessary. Hope that helps. Still waiting for parts to return at this time. Jim.

Nice work. I’ve been contemplating making a splitter as well but have my hands full with my axle swap at the moment. I’d love to see some more pics on how you attached that. Again, nice work. Jim

Agreed. I like skillards stuff I just wish the splitter fit 240’s a little Better. There is a really lg gap between the core support and the splitter that isn’t there with the 280.

I use the xenon dam in Redding California and it hits 100-110 all summer long. I built a support for it and it’s rock solid. I have some pics of the support on my build log in the Gen III IV V8 forum.

72 240Z LS1 T56 full suspension upgrades and 17X9&9.5 with fuel cell. 2500lbs wet. 2700 50/50 balance front rear and crossed with me in it.

Beautiful car and well executed.... I’m just not a 2+2 fan in general

UPDATE: DSS is asking for the stub axles back again for one more try. Sending them back today. As frustrating as this has been, I will at least give DSS credit for repeatedly trying to make it right. Side note: the CV axles appear to be too short as well........ With all of the drama surrounding this conversion I measured every single part yesterday and the axle bar is 1 inch too short. DSS asked me to bolt up the stubs when they arrive and take measurements...... They will replace the axle bar once they know the stubs fit properly. Just another step to take the half shaft cv axles back apart and send them back for correction. As long as I'm back racing by march-april I'm good to go. Thanks to the community and vendors that have reached out in private and forum for all the help and support. Jim

With all do respect newzed you have contrbuted nothing new to the solution of the problem that I had not already addressed many weeks back with DSS. I may not be using terms that agree with you.... I said “bind and won’t turn” and you prefer “won’t spin”. Your suggestion of filing off a dust cap is impossible as we are talking about solid billet machined parts that are meant to be to spec. You just can’t take a file to this stuff and call it good and I don’t own a lathe. I purchased these parts at great cost per DSS selling them as bolt on and in regularly use on many S30 Z’s. They have since admitted that they have NEVER had this stub axle on 240Z and admitted that there stub axle was previously copied off of an unknown Datsun stub axle they were told was an S30. I have supplied them all of the measurements using my mics and calipers for the risers so the bearing would fit per spec. Unfortunately, the first riser was not machined to measurements I provided so they did them a second time, this time per my measurements and they are perfect. Great, however the billet machined shoulder then cam into contact with the housing and again would not spin. Soooooo I sent them a stock 240Z OEM stub axle along with their axles with the understanding that DSS would machine into the billet stub axle the proper recess and width allowing the stub axle to fit as OEM with the stock stamped dust cap. DSS sent the axles back to me with shoulder machined down but without the necessary recess. I called them concerned they still would not fit however, per their instructions, bolted them back up as they were “within .005 tolerance of OEM”. I bolted them back up and they continue to press against the housing and will not spin. I called DSS with the bad news and they said “sorry, we didn’t think the recess was that important”. My response was “why didn’t you just machine the axle to match the OEM one I sent”? There Response- “Im not sure i need to talk to the machine shop”. As of this afternoon, DSS has requested I send it all back one more time and they will make it right. I’m going to give them that opportunity again as I am to far into this to just turn back. So, after month of emails, pictures, and sourcing hardware to fit (since the supplied hardware hits the differential on the adapter side of this conversion) I am again hoping that DSS machines these stub axles to OEM spec. Keep in mind, this is advertised as a “bolt in no modification kit”. Im really not offended that I’m not making sense to you. I’m offended and ticked off that I was sold a product that has never actually been bolted on to a 240Z and that I have been patiently (admittedly sometimes not so) trying to help them produce a useable product from the other side of the U.S with phone calls emails and pictures. The final straw is sending them an OEM axle with the instructions “make a copy of this” and it still came back machined wrong. Every point you have made regarding bearings and risers and clearance I agree with fully and in fact I communicated to them to fix those issues as they arose. It’s been a long process. I’m sorry I can’t satisfy your deepest need for every piece of communication and I honestly can’t tell you why they keep getting it wrong. Funny thing is, they can’t explain it either, but they sure as heck are not blaming me. Lee thanked me for my patience with all of DSS mistakes. Getting into a war of words is not my bag. I’m bummed out this crap is clogging up the forum. I apologize if I offended you. I’m really just a hard working guy that loves Z’s and gearhead culture in general. I’ve been building and racing for most of my 50 years of life (first kart and motorcycle age 5) and building cars in my garage is my therapy..... supposed to be fun. Given all my frustration with this purchase, i just needed a place to vent and I really want others to avoid the same. So hearing that I’m a whining complainer that doesn’t know what the hell he is saying and is incompetent to turn a wrench hits where it hurts to be perfectly honest. Agree to disagree is cool with me, time to let this squabble go. With respect, Jim

Thanks you. Good luck to you as well

Richard.... They have not responded yet. Ill let you know. NewZed: with all do respect you have absolutely know idea the depth of conversation I have had with them and the extent of the problem. You cannot file the dust cap down and make this work, that's is a completely ignorant statement! This is a crappy design and machining problem, a fact that has been supported by other vendors that are highly respected in the Z community that have reached out to me in private in order to help me find a fix. You seem to think I'm some kind of dumbass that can't turn a wrench. I do not have the time to relay every communication I've had with them (DSS) to the hybrid community, just a general overview. Please quit trying to read between the lines. Respectfully, Jim

That has been addressed twice by DSS with machined spacers the first was wrong and the second correct. The point of contact is the shoulder / dust cap..... it is too wide and 3mm too tall and contacts the outside edge of the upright housing. This was supposed to machined down to spec of OEM to match the OEM axle I sent them on the 3rd attempt however it was not done properly and remains a point of contact. I spoke with DSS yesterday along with multiple emailed pictures and an offer to send them an upright and another axle for reference..... they will get back to me today on how to approach this yet again. In the mean time, checkered Joe has reached out to me (great guy by the way) and has an alternate solution for me if DSS can’t or won’t fix the problem and returns my money. I will know more later today. I will admit that lee at DSS was very apologetic and seems willing to fix the problem..... I’m just tired of doing this repeatedly and really want my car back. My race this weekend is obviously a bust. Jim

That’s pretty odd. I’m not to familiar with johns kit but can’t you shim the mounts and raise the front a bit?

The outside flange contacts the housing. It has assembled all 4 times correctly. DSS has already repeatedly admitted that the stub axle is not machined properly that is why they have repeatedly try to fix the problem. Unfortunately the problem has yet to be fixed. I am still working on a solution with DSS. And yes, when I say it’s binding I mean the wheel won’t spin. Thank you for your points of help...... this can’t be fixed until the product is machined to OEM spec.

No you are incorrect. DSS sold me the parts and advertises them as a bolt on solution used on “many Z’s all over without problem”. The stub axle has never fit in any way shape or form. I am on my 4th attempt to send them back and again have them machined to spec to match stock stub axle. The issue at hand is that when the stub axle is installed it binds against the housing and won’t turn. I’m not sure how much more information/communication I can give them aside from sending an axle with instructions to make a copy. I support product from vendors on a regular basis and after 30 years of building cars I know that a little modification is typically necessary to make things work, however $2600 and 4 months with numerous emails and pictures with measurements from me since I placed my order and they still can’t get it right. My frustration comes from providing them everything to make the right product and them sending me something different repeatedly. Thanks for your input, I don’t mind be reminded to stay the course or not to lose focus blaming others unfairly, but this situation is all on them. I’m still waiting for reply from DSS I’d they wish to try again to get this right. Thanks for the picture provided, I’ll pass that along as well. Respectfully, Jim

In the event that DSS doesn’t come through with a solution..... anybody know Joe for modern/checkered? I can’t get ahold of him. I have not heard back from Whitehead performance either. Thanks. Jim
