starting with mustang ii, but need to move too many things around, beginning with KPI/SAI, so I really prefer a custom spindle.

ANy ideas? I have been browsing all the suspension forums but havent found a source yet.

also, I guess to explain further, I am working with a cobra rep, so it is extremely narrow, thus having short control arms (11.8 and 7.5 respectively and not significant room to grow)

I have the ball joint locations identified to make it work pretty well. (that is about 1.3-5 drop at the upper and 1.8-2" at the lower) THat leaves the RC around 2.5" without less than 2" of RC movement in travel and decent camber curves.




I want good ackermann (50-70%) as I will be autocrossing. The mustang 2 spindles in it now have basically no ackermann effect.

I dont like much KPI for the same reasons, as steering angles get high and I want the outside wheel cambering up with steering. M2 spindles in it now have almost 13 degrees. I intend to go with 5 or 7 degrees in the spindle.

Stock Car products says they can do it but I cant seem to get their attention.

(I am missing one dimension from their sheet, the offset from bearing face to the KP axis... it may be that they dont want to screw with me because of that, but I cant fix that dimension without mocking up the spindle with the brakes and making sure I can clear the steering arm and tie rod with the inside of the brake rotor).

The ATS AFX spindle works good in the factory Mustang II geometry. You'd be amazed on what is changed with just the addition of the spindle by itself.

You might want to call Tyler and shake things down.

you might try martz. i know they make their own spindles for the sub frames they build.

thanks,any other ideas? The ATX is pretty far off m2, and Martz is hard to reach as well.

I would think that spindles would be more commonly fabricated than it appears.

Coleman or SCP. SCP is a little wierd but they can do it. Coleman is a great company.

we are able to fabricate custom spindles, from full billet like out 65-66 mustang spindle to a full boxed unit out of 4130 TIG welded. We just purchased an CNC mill and are in the process of setting it up so we can have the manufacturing in house. Please give us a call for any questions, we are easy to reach!

i check my e-mail several times a day so that is also a good way to get a fast response.

KPI/SAI are like a second language to us!

Louie (the engineer of the company) is the mastermind behind all of our suspension geometry and design, as well as a CAD guru and machinist! Give him or me a call and i can set you up with him.

I'd want to see a lot of FEA data before running a one off billet upright. Ask the AFX guys what it takes to build a one.

Dealing with SCP:
I had a pair of spindles made by them. I started out dealing with a guy named Tony (builds fabricated spindles). After discussing dimensions (he was very friendly and walked me throught the whole process) and the intended use, we mutually decided that the fabricated spindle wouldn't be quite strong enough. He recommended that I go with their SuperSpeedway spindles. That required dealing with a guy named Chris (their SuperSpeedway spindle "guy"). That guy is kind of a jerk, very knowledgeable, but a jerk nonetheless. I had a really hard time dealing with him. Tony went over from his work, talked to Chris, and got my order completely squared away. The end result is... I got exactly what I needed

SCP is great to deal with, those guys really know uprights. I have also had great luck with Coleman. I would stay far away from custom built Al spindles, very few guys are building them and part of the reason is the R&D costs associated with FEA and cycle tesing. Anyine selling a Al upright without having done the homework is playing with fire.

There is nothing wrong with a billet spindle, some even use billet spindles for Class 1 vehicles with no issues. The key to the billet is the design. We have been in the R&D stage for about 2+ years and are in the final prototype and setup for manufacturing stages. There will be test results available, nothing we sell will ever have a strength issue. If anything; we build strength into our products from the begining.

For those not into the idea of running a billet spindle, we will also be making a fabricated 4130 TIG welded splidle that will house the same great geometry and have added srtength. This 4130 spindle will weigh a little more than the billet and be about the same price. These will be available before the entire billed setup is released.

However, that 2+ years of R&D and FEA needs to be done on EVERY new design of the same component. Not sure most guys want to wiat or pay for 2 years of work for one pair of custom designed uprights.

Getting your prototype off the ground is great but change one aspect of the design (add some KPI or change the pin height) and all tests need to be done all over again.

yeah we are getting there for the billet ones. Our goal is to have the final done and ready to ship in AUG, if we dont make it thats ok too. Im not going to release a product that is not fully tested.


On the other hand, we can build a 4130 setup that is custom and will be plenty strong for the application. I prefer working with 4130 simply because im a welder and TIG 4130 is just plain sexy. The only drawback is that the cost for a one off set will be more than the production series.

Are the AFX spindles available for the MII?

outstanding! I will be giving you guys a call. I appreciate all the input.

I have been trying to reach tony, but he just seems too busy or uninterested to talk.

Heres a picture of mine.I had same problems with stock stuff . With these i got the ride height and needed KPI .
