This is an '02 Boss chassis. This is supposed to be a copy of a Mastersbilt car, but I am not certain if it is a copy of the "wide/combination" car, the "narrow" car, or the "smackdown" car of 2002. Thus, I am not certain the best way to locate the rear end.
The car originally had a short straight panhard bar mounted on left side of pinion..I installed a j-bar, middle hole on right side of pinion and 7.5" up on frame.
I was told by one person to set it up so the right side 4-bar rods appear parallel with the frame rails. Upon doing that, I noticed the left side bars appear at a relatively severe angle, in the range of 15-20 degrees from parallel to frame rail.
Currently I have some distances:
back of left rear rotor to outside frame rail: 7" ;
back of right rear rotor to outside of frame rail: 4.5"
distance from 90/10 plate on top of rear end to inside of right frame rail: 18"
distance from back of left rotor to center of shock mounting point on left birdcage: 6.5" (This seems short compared to some setup sheets)
Here are some suggestions I have heard..which should I go by?
-Make it so distances from each rotor to frame rail are the same (In this case, that would be about 5.5");
-Leave it so the right side bars are parallel to frame rail, and relocate left side birdcage inboard so the shock mount is more like 7.5" from rotor (The brake rotor bracket on the left side is part of a clamp on bracket separate from birdcage so this is possible..the right side brake rotor bracket is welded to floating part of birdcage);
-Align right side front and rear hubs (Make them equidistant from string line placed parallel to frame rail away from car);
I realize lateral location is important for weight placement, but am not certain how to approach this as I am not certain what setup sheet I could use to make that happen.
Thanks for your help
