Suspension/Wheel alignment adjustability

[drunkenmaster]

geez, thats a fairly strong opinion but short of adjustable control arms which is a fairly extensive modficiation in my opinion, I dont see how else to correct the camber due to the lower ride height my new suspension will provide.

Good food for thought though, thanks for your $0.0263189 AUD

It's only 1 persons opinion, and I was really conficted when I removed them. I loved the great & precise handling, but it was such a pain to deal with the condition of the roads around here

FWIW, the adjustable control arms that I'm familiar with would have the same issues. Solid mount.

I haven't looked into them (at all), but what about those "camber plates" that mount up top of the strut?

I will have to discuss that with the local authorites.

The beauty of an adjustable bush or camber bolt used on newer cars is no one knows that they are there.

I am not sure what it is like in the USA but my car will be extensively reviewed by an automotive engineer approved by the road authorites when I try and road register it due to its significant deviation from standard and I am worried that cut and shut control arms or adjustable twoer plates will not pass safety requirements/design rules. I will have to consult them.

I will agree with Carl. The discussion of delrin bushings has come up many times and the final consensus for road use is a big....NO. The is a reason why it's good not to tranfer tons of vibration to your unibody. I know many think the Datsun engineers were complete idiots, unfamiliar with modern technology. Why else does everyone hate plain old rubber? Are you building a road car or a race car? You can't have it both ways, and have a desent ride. If your car rides like a brick on the street, what are you damaging besides yourself? The fact that a Z handle pretty dang good even with a worn-out suspension tells me that the Datsun engineers knew what the hell they were doing. You want to put in delrin, polyurethane or even solid steel every where, that's your business, but you don't need it. One of the guys who raced Z's said, the average driver can't even get everything out of a stock Z, much less one with all kinds of fancy mods. If you're going to keep your Z forever, don't set it up to last less then that by substituting stiffness for lack of driving skills. Build your car for American (or Aussie) roads and you'll be happier.

I understand.

However I have upgraded my suspension and brakes to suit my non standard motor. Since these items were being visted anyway, I added height adjustable coilovers to the struts. Now when I set the height to what I feel to be optimum, I am sure this will end up being lower than standard ride height which from my experience will add negative camber, likely too much which will go past the point of aiding cornering and just wear out the inners of my tyres. The main reason I want to add adjustability to camber is so I can correct this, and while the whole front end is apart in my garage, now is the best time to do it.

I agree solid bushes are not the way to go on a road car, I was not aware initially that they were solid. I am not real keen in sectioning my control arms or slotting my strut towers either. I have OEM rubber bushes to go in now, so I suppose I will just have to wait and see how it all comes together.

No one can fault you for thinking this out now (while you have the car disassembled). Far better to be thinking about it than not thinking about it.

Good Luck in finding a solution that will work for you.(and the inspectors).

I plan to use mostly OEM bushings, with a few choice uses of polyurethane. The area that the Z is lacking the most is in sway. I will upgrade to a heavier front bar and add a rear one.
