- Interesting idea. I'm not sure the links are adjustable (other than bending)
- but have new urethane bushings to reduce deflection. I am thinking that the
- car is weight biased on the left side : (please correct any logic flaws)
-
- 1. A RWD solid axle vehicle torques the rear axle, thus loading the left wheel
- and unloading the right wheel.
-
- 2. The driver sits on the left side. (adding 150-200 lbs to left side suspension)
- Estimate 70% left & 30% on the right side. --> ~115 lbs more on left side.
-
- 3. The battery sits on the front left side (This particular fbody anyway, 40lbs?)
-
- Adding items 2 & 3 above thats about 155 lbs before touching the gas!
- The reason I bring this up is due to the behavior of the car during a recent rain
- storm. Light acceleration on wet pavement produced right wheel spin very easily.
-
- I guess I need to find the static weight on each wheel to get an idea how
- the weight is distributed accross the suspension. I suspect it will show that
- more weight rests on left front and least on the right rear.
-
- Any suggestions on how to do this?
