Two quick questions.

1. I have heard TONS of theory and conjecture, but nothing definitive. Have you ever found a relationship (good or bad) between mounting a wishbone above or below the rear end housing? I have heard that one way will control roll rotation slightly better than the other. Is this true?

2. Are there benefits to running dual frame rails all the way to the front of the car, or does it do the same thing if you tie them in at the mid-plate area?

Thanks a lot,

Michael:

1. The wishbone definitely needs to be mounted on the bottom of the housing. Because the 4-link bars are on a push (compressing/pushing forward) they need to be triangulated on the bottom. The only reason people put them on the top is to make it easier to install and remove the third member. Performance-wise, they should always be put on the bottom. It triangulates the car and when the rear suspension does have some body roll to it, it will rotate off the bottom bars and not the top bars. If it rotates off the centerline of the top bars, the bottom bars become unsquare with the chassis and cause the car to move around and become unstable. Always mount on the bottom!

2. When we build double frame rail cars we take them to the front. We feel that it ties the car in better if you go all the way to the front. Definitely tie it into the mid-mount area too, but it is better if you go all the way to the front.
