UPDATE:
So what I was machining out on the lathe was a adapter sleeve for 1984ish-98ish S10 balljoints, super common, CHEAP!, and much much stronger then the Vega or Monza ones that could fit in the factory sleeves. They also use spindles which are a simple swap into the Vega's front suspension thus giving her bigger more common brakes.
arms with the old balljoint. new sleeve hole marked out, 1/8th inch inward from the factory BJ position to help with the different location of the BJ in the spindle. its about 1/4" total making more negative camber. We figured that it might be worth having the additional range of negative camber since she will be autocrossing this car.
after cutting, test fitting the sleeve
Welding the sleeves in
and after hammering the balljoint into place
This isnt all what is going to be modified on this control arms. We are going to make a swaybar mount, on a nice evening walk this summer in the woods we came across a burn't Chevy Monza left abandoned in a field, after asking the closest house if they minded if we picked a few parts off it got the front and rear sway bars, as well as the powersteering setup and power brake booster. all in decent shape. Turns out it was a Spyder model as well so it should be the larger sway bars.
Also! we plan on running Fox-Mustang front and rear springs. little bit of research comparing spring sizes and weights Ive found they are SO simular she should be able to use my old lowering springs out of my Mustang. Both mustang and Astre utilize a 4 link rear suspension and are balanced fairly simularly (front engine, hatchback) Might require a small amount of deepening of the spring bucket.
Again Cheap! and More common parts....catch a trend ;)
