Ultimate Adjustable ARB?

[260DET]

Thats anti roll bar, stabiliser bar, roll bar, whatever. Poly bushes may be an improvement over stock but after testing its obvious that the front ARB on my S14 suspension 280ZX circuit car and its mounts have to be upgraded.

 

Under heavy load poly bushes squash out allowing the ARB to move rather than twist. I do have a spare JDM 32mm hollow bar which could be used, providing it can be mounted using bushes that don't deform significantly. Or perhaps a universal type bar with removeable arms may be better, although a hollow bar for weight saving is preferable.

 

So who has tried what and can recommend something? Either a universal type kit or perhaps some material which can be machined to make bushes that don't squash out. That is the preferred option but I'm willing to buy a kit if it is the ultimate solution.

For example, the tubular bars here look promising but there is a lack of info as to the mounts http://www.howeracing.com/Suspension/Index-Stabilizer-93Up.htm

Are those eye things the mounts? How?

THK Powergrid is a vendor that advertises in Grassroots Motorsports magazine. (http://www.powergridinc.com) They make adjustable end links for bars. I talked with them months ago and was told that links could be made for my track car if I would supply them with dimensions. Somewhere between my busy life and my lack of knowledge as to how to adjust them for my needs, has lead me to not contacting them again. Perhaps someone with real setup knowledge will chime in and describe the merits of having the ability to adjust the end links.

Yes, the eye things are the mounts. How? Well, they get an eye that is larger than the bar, thread the bar through it and attach it to the control arm. That's it. The bar just flops around inside the eye, so far as I can tell. I just subscribed to Circle Track magazine and I couldn't believe what I was seeing when I saw one installed like that. I guess the idea is that if you wear out a bar off of a Chevy they're so common here that you can just go get another one, and in the meantime there is no bushing to create any bind. Picture here:

I like the way my setup came out, but I still haven't used it yet. Can't beat heims joints for freedom of movement and lack of stiction. I can tell you that when all bolted up the thing moves really nicely.

Is your setup similar to what Tube80z mentioned in this thread Jon?

Here is a pic of another solution, only thing is I'm not sure about welding the spring steel hollow bar.

[JMortensen]

Yes, and there are pics on page 6 of that thread.

I believe those eyelets just slip over the ends of the sway bar and the other end of the brackets clamp to a control arm. The "loose" eyelets that jmortensen posted are there just to stop the ARB from sliding out of the eyelets on the brackets. That's how they get "infinite" adjustability. Another method I have seen is where the ARB bolts directly to the control arm (or other moving suspension piece) and they technically don't need any brackets, etc.

 

OP: several of the posters on this sub-topic are amazing fabricators (jmort is one of 'em) and if you search their names under this sub-topic you will wind up with several different methods of execution that do not feature poly/rubber.

Jon's design is a good one but I like the idea of fabricated arms which can be drilled for some adjustability. So I'm going to shift a question on welding the arms to the bar as done in the blue one pictured above over to Welding/Fabrication.
