    Sounds like the decision is made, but for the record - I ran the old version of the SPC arms on my '71 for years. That car probably saw 100 Autocrosses during that time. It was running 16x10" wheels with 265/45/16 Kumho 710 autocross tires and a 500HP small block.
    If I couldn't break those arms under those conditions, you certainly won't.

    Thanks for the reassurance....

    I am now getting in deeper than I originally planned but not fully committed due to funds! I am feeling that if I am going to have the front end apart I might as well do a brake upgrade to a C5 set up at the same time...once I do that I am in for new wheels...I might as well put in adjustable G-braces while I am at it and it is winter....Rear brakes will definitely have to wait.

    Planning on Team III LTIII wheels. 17x9 if they will fit, if not 17X8 with 5" BS. 18x9.5 with 5.5" BS for the rears. 245/45/17 (or 55 if they will fit) and 275/40/18 in the rear.

    I have tall upper Ball Joints I got from Custom Works, I can't remember for sure what brand they are but I think they are AFCO. They are in my car now.

    I will study the installation instructions closely!

    What type of Anti Seize do you use? The copper stuff or something else?

    Thanks!

    I have a big jug of Chemsearch Thread-Eze. It's the silver mil spec stuff, don't remember where I got it.

    If you looking for cost effective way on lower control arms, keep the original arms, use a high grade ball joint and delrin bushings.

    I'm running the SPC Adjustable Uppers with tall ball joints. Stock lower arms with GW Del-A-Lum Bushings...
    Good bang-for-the-buck setup IMO...

    Man, that's an expensive case of the "might-as-wells. But it all makes sense.

    I know...agonizing over it....I don't want to take it apart twice. Maybe I am just being lazy....Once I upgrade the brakes I am committed to the wheels.....I am dragging my feet right now on it...I could just do the UCAs and Gbraces and call it a day for now.
