Back to step 4 and 5 update.

I think most people wouldn't bat an eye with the Kinetix arms, but then again, SCCA Nationals sounds like it's run by a bunch of lawyers.

There are options its just that they are substandard in their adjustability and in some instances build quality. The SPL arms are pretty much the best on the openly available retail purchasable option list.

Extracting a stock bushing and replacing it with an offset bushing of much higher duromemter is not misguided. Energy Suspension and PowerFlex, to name a few, have based businesses off of this practice. Its not metal but it has much less deflection than a rubber bushing sandwiched between two metal bushings. The original intent on that design probably lies somewhere between creating a softer ride by mitigating some vibration and making a responsive steering system fully designed around the car being track oriented. Can't have both, need to settle somewhere in the middle.

What was the gap between the winner and the protester?

Do you think that bushings, shot up with nails, had a remote chance of causing the gap?

The fact that arguably trivial rules are made in response to protests leads me to believe that there are a lot of drivers that simply protest those they can't out-drive. -and making rules to keep people like that happy just seems like bad policy.

I understand there's money on the line, but I would have a hard time protesting another driver under many, if not most of the rules, unless I thought he had a real advantage and/or the gap was very close.

What about the Stillen arms?

Looks like the ball joint is a no-go on the stillen A-arms.

Shamu

Thanks again for stimulating my thought process on this rule.

Neimad

A ball joint is a spherical bearing is a bushing=NO?

Damn...If the amount of metal in the Stillen ball joint weighs the same or less as O.E. is that ok? The rubber on the O.E. is just grease retention, not the bushing itself.

the kinetics mentioned will suffice....and super easy to adjust trackside...

Made a mess tonight, still not any closer to getting the bushings out!

Did run to pick up a vise as I didn't have one. I'm hoping that will help me tomorrow evening so I can get some real work done. Hopefully.

The rule is that the amount of metal in the bushing to some other material, can't be more than it was OEM

i have SPC a arm and run in BSP.
Ima get Kinetix a arms, and later, get it customized to have caster adjustability

This is speculation on my part, but Kinetix ones *look* like they might be the lightest as well.

Chris,

I sent you my bushing puller via FedEx. You'll get it tomorrow.

Shamu

Well submitted an appeal to SEB on 15.8 C today asking for revised wording that will allow non solid bushings that might have a little more metal than stock.

In the mean time I'm working on a new solution that I havent seen anywhere.

Shamu

....So if somone were to make a control arm bushing from non metal composite material would it meet SP no more metal than stock bushing rule? Certainly wouldnt have more "metal" than a stock bushing.

Yes, that is what we have been talking about from the beginning. Have someone machine a poly or hard rubber bushing... Done and Done

I made some out of Hydlar Z and have been running them on my 350Z for about 4 years - its a no point mod with NASA TT. I actually made two sets and Chris has been trying to install the second set in his stock UCAs.

Shamu

Im talking about working with someone to offer adjustable control arm on aftermarket turnkey. No fabbing, no offset bushings, etc Designed to use this material. I think there is a solution coming our way soon with very high quality arm for 370Z. Any interest in 350?

Shamu

Why is Chris pulling stock steel bearing then?
