Technical I-beam IFS and Banjo Transaxle

These twin I Beam equipped race trucks actually handled quite well, much to the amazement of the other brand teams. The camber curve, although more aggressive than a double a arm set up, worked quite well and was predictable. Bump steer, within travel range, was minute.

 

So what you thought about was taking it with cradle and all straight out of the VW and flip it around, as it sits now, with the engine in front of it and and have the arms point forward?

Wouldn't that make it squatting at launch and lifting at breaking, or did I miss understand you thought train?

 

No driving-torque reaction in the arms, so no torque-induced squat. Getting the rear to rise on launch - which is desirable - will depend on the arm pivots being below the extension of a line connecting the rear wheel centre and a point at cg height directly over the front wheel centre. (I'm talking in 2D, side-view terms. This applies to all independent rear suspension systems and also DeDion axles and live axles with bird-cages. For conventional live axles the line goes through the rear tyre contact patch rather than the rear wheel centre.)

The system will produce anti-squat under braking if the rear brakes are outboard, pro-squat if they are inboard. The former is good for transient braking, producing an impact reaction against the car's inertia when you slam on the brakes, whereafter the rear rises. The latter is better for steady braking in so far as the slight hunkering-down reduces the cg height slightly and thus reduces weight transfer onto the front wheels slightly.
