I've been working on having a fully adjustable rear camber and caster kit for the 280ZX with a friend of mine who does an amazing kit for the Datsun 510.  The 510 shares a very similar trailing a-arm suspension with the S130 280ZX.  I just sent over a rear cross member and a-arms  to Byron and in comparison the 510 is MUCH larger than the 280ZX (about 4 inches to play with as opposed to the 1 1/2 inches on the 280ZX).  That means the 280ZX rear cross member adjustable bracket needs to be completely redesigned from the original 510 kit Byron makes.  Byron is willing to redesign the bracket to work with the geometry of the 280ZX but he needs 15 buyers just to break even.  He's willing to do the project if I can get 10 guys to commit to buying a setup in the hopes that he'll sell at least another five just to get his money back out (that's not including all the time in his design, etc).  Each kit will be $300 each and will allow you to adjust both the camber and caster of the rear end.  This is a MUST if you are lowering your 280ZX and/or if you are racing or auto xing your car and want to be able to tune the suspension.  There is currently NO other adjustable systems on the market for the 280ZX and the only option is to use toe bolts and/or slot the rear cross member but there isn't a lot of material to do any slotting as it is and the adjustment range is minimal.  For Byron's kit you would have to cut off the stock mounts and weld on the new ones which is fairly straight forward but does require welding - this is not a bolt on kit - that would require a complete cross member replacement and would be very expensive.  The kit would be complete with everything you need other than removing the bracket and welding the new kit on.

 

There's a bit of a thread on it and the installation is over [URL="http://www.zdriver.c...966/"]here[/URL]

 

Here's Byron's 510 kit. Build thread is [URL="http://www.the510rea...ilit"]here[/URL] and the install thread is [URL="http://www3.telus.ne....htm"]here[/URL]

 

If anyone is interested in a kit please post to this thread!

What about toe? on my ZX I have about 1* of toe from it being low. Also what about modifying the actual trailing arm? 

 

I know Purepontiackid basically chopped up his rear control arms and welded on heim joints in an offset pattern. With this this and heim joints in the regular location, toe would be adjustable as well. 

 

This is a pretty neat kit, how much more time before you think they get made?

We need ten guys to commit before Byron's willing to take on the task then it will likely be a month or two for the design and drawings and getting a test set on a car to start stress testing under load, extreme driving conditions, etc.  This is a complete redesign from the 510 setup because of the smaller space available on the 280ZX for the brackets/body clearance.

 

This will be a toe and caster adjustment.  PPK's mod is a way old school mod they've been doing on 280ZX's since they came out and really the only solution out there until now.  I've been bugging Byron about doing a set for the 280ZX and he has a small window of time to take this on before he moves on to his giagantic list of stuff to do.  Regardless he'll put the time and effort into making this perfect - that's how he does all his stuff and he's an amazing supporter of the Datsun community.

 

New control arms would be great but much much more expensive.  There seems to be little interest in anyone making up a set anyhow - I've asked and most manufactures aren't interested.

It will be a similar kit but it will need to be a complete redesign because of the much tighter constraints on the 280ZX in comparison to the 510.

I wouls like a set for my car. Currently I have installed the special products adjusters, but they are limited on their operation, and I have never been happy with them.

Ine thing I would like to get some clarification on is , when the kit is installed, how do the half shafts look with the car on the ground. Do the shafts promote the squatting actio the ZX cars like to do, or have you taken the angle out of the shaft for the lowered cars so that it will not squat like a stock car does. I would really like to fet this part if it will fix some of the zx problems.

If this is still on the table, count me in.  I would definitely commit to buying a set.

I think I've seen this same thread on ZDriver. I'm planning on copying it, hope that doesn't upset to many of you! These brackets are the final piece I need to get my car back on the ground. If someone gets a kit made up in the near future I'd be more than happy to buy one, but I'm just too impatient. I know there is enough demand for these so if I get one put together, I'll have more made up.
