Spring Plate Ruminations

[evilC]

There is only a modicum of camber adjustment on the spring plate and if the assessment of my set up is correct the majority of the camber is down to the ride height. The camber is affected on the 944 spring plate by hinging the spring plate in the middle so that it can change the relationship with the inner pivot. It is a fairly complex geometry to understand let alone describe and it took me some time to work out. Fortunately, it is easier to get the results without worrying about how it happens.
Squat on the rear (as is dive on the front) is about the relationship between the front/rear lines of suspension action in the longditudinal direction and the centre of gravity. As the mass of the vehicle will stay constant the lever arm (the distance is increased as you lower the vehicle) increases and therefore you will induce more squat. Altering the spring plate will change the squat but that assumes that you are not using it for camber tuning. I would suggest that you set the vehicle for camber and toe in first ignoring squat and then when you have acheived all you want from that you can adjust for squat but at least you will have a base setting that you know will work. You don't want too many variables to sort out as the permutations can be mind blowing.
The adjustable spring plate does not affect the fitment of wheels and tyres.
The 924S is the one to go for since it has alloy arms and disc brakes off the 944.
