I'm confused. I thought the Lotus 29 suspension was
offset not
staggered . I'm probably totally wrong but I always understood that the Indianapolis Lotuses and the Cooper T54 ( model?) before them had unequal length wishbones so that the centre of gravity was offset relative to the centre of track. However the axles were set at right angles to the centreline of the chassis so that the rear wheels tracked the fronts.
If the suspension is staggered, the axles are not at right angles to the axis and may not be parallel to each other. The result is that when the car is coming towards you in a straight line it crabs and you can see all four wheels with one of the rears visible between the front wheels and the other out to one side. So when cornering neutrally the car appears to be understeering or oversteering.
I once owned a Triumph Herald that had had a very poor chassis weld up done. The back axle was not at right angles to the chassis, so when I was going straight the nearside rear wheel was nearer the kerb than the front one. I never noticed it was crabbing until I saw my wheel tracks. Under heavy braking it did slew slightly as the centre of mass was off the (average) centreline of the wheels but I simply put it down to the camber. I suppose it was a bit like a boat and handled better (or it being a Herald less worse) on left handers than on right handers or vice versa but it wasn't enough to notice.
I know that these days NASCAR and Indy cars are set up with a degree of stagger (I don't know whether this is 'tail out' or 'tail in') but I don't know if the idea was around in the early sixties.
This is probably one for the technical forum or over on ten-tenths where a lot of posters race cars.
