    My intentions are to do the short cut install by only lowering the rear of the sub frame. That may change of course but that's the current plan for tomorrow.
    After reading some other folks experiences with these bushings and studying them for awhile I decided to make a change to the set screws.
    They come with 6, 1/4 x 20 set screws in each sleeve. Some one mentioned this as a design flaw. The six small set screws contacting the hex flats on the control arm don't provide enough contact area to effectively keep the sleeve static
    Well just to kick this off I decided to start with modifying the sleeves.
    Drilled out the 1/4" holes and tapped them for 5/16 x 24 set screws, I'm only going to use 4 set screws per sleeve, this will force the sleeve to contact control arm for it's entire length on one side and provide a robust three point contact with the hex shape of the control arm. Will be using Loctite 242 (Blue) on the set screws.
    Everyone please chip in with your tips or experienced advice.

    Check

    to make sure that the set screws don't interfere with the red anodized bushing housing when you do this.

    Thanks Dr O, these are the same length just larger diameter and finer thread, they are the cup point type. I searched two good local hardware stores for the serrated or pointed type, not stocked.
    Thanks, will certainly watch out for that.

    Re: Set Screws
    I use McMaster-Carr for all my hard to find parts. They have a great on-line catalog. If I order B4 noon, it arrives next day UPS.

    Sleeve's sliped on like a glove

    no grinding necessary like Keith had to do.

    Metalman, thanks for that tip on hard to find hardware and fasteners.
