    Okay, so do you have any rear suspension?

    Take a picture and then draw on it with Paint showing what you're trying to do, if you can.

    If you don't have any suspension, then a 45 degree angle would be the best.

    I think he means one of these rods. There is not a majic angle. It will be different angle and length rod for each ride. Unless you got a Cuda or Pirahna then a couple guys here can help a "tad" (lol). But if its your own design it will take some figuring out to find the spots.

    Are you sure you have enough rim offset to clear it on the hub if its a rod like this? Would bite to find out after installing the rim hits it.
    Now that NOBAMA has PROVEN he is the absolute WORST president in the history of history Jimmy Carter can thank him for stealing the dunce crown.

    Lets hope the next guy repeals NObama care along with the rest of the stupid crap this blight on our windshield has done.

    Trail and error or SERIOUS mad math skills.

    Talk to RickS and Doug Heim as they both due these.

    There is a VERY in depth thread on this on this site but the name escapes me at this second. I will search for it.

    If you got the idea from that thread then of course you know about it. If not it should help enlighten you and ask a question or two of the people in it for more.

    Draw up a 2D (to scale) view of the suspension arms and bearing retainer looking from the rear of the buggy. Pick out a point on your bearing retainer to represent the rod end ball. (somewhere between the upper and lower a arm pivots.) Now show the arms and this point in three positions. (full droop, midway, and full bump.) draw an arc connecting the three points. The center point of this radii is the forward location of the rod end ball. The length of the rod can be as long as you want. (longer is better) The seat will probably limit the length of the rod.
    Moving the rod end up on the bearing retainer will raise the forward point.
    Moving it out on the retainer will move the forward point out. etc.
    you'll probably make a few drawings before you get it where you want it.
    Every time you pick out a new position on the bearing retainer you need to retrack the points to find the forward mount point.
    And like nutz said, watch the rim offset too.
