BTW Vince, have you noticed horrible bumpsteer in your experiences with using these spindles?
To me it apprears bumpsteer is HORRIBLE and it can't be fixed, just minimized. I pretty much gave up on setting up a dial indicator to measure it and have just used a tape measure while I roughed in the tie rod angle on the Nova. The first 1" of bump is okay, worse than any suspension system I have designed or set up on circle track cars, but can be tolerated. Beyond 1.5" of bump it goes to heck very quickly. Looking at my own Vette it appears they set the ride height such that the lower arms aren't parallel to ground, but angle down a bit so the car goes from toe in to zero at parallel then start toeing in again on bump - something I do NOT want at all on a track car. I want one direction of motion during bump. Anyway, setting the car up as they did gets some more motion without huge toe change, but still, not great.
The rears are oriented with the toe arm back which actually means the rear toes OUT on bump. I can't imagine how that bad idea got incorporated. Nonetheless, I am now working out swapping the rears on the Nova and figuring out how to put the toe link to the front.
I have been super tempted to take a torch to the toe arm on the struts but have no idea how that would hold up with the aluminum material on the track. If it was a forged steel spindle I would be bending that puppy to fix this. For now I intend to see how it works out. I will be limiting suspension motion anyway with stiff springs and bump rubbers.

Also anyone considering building their own control arms my machinist has the specs to make upper and lower ball joint pucks.
