Old Man,
thanks for the answers. I'm not too strong with the low ball/high ball thing, as I don't use alloy hubs & bulkheads myself.
With tire width I mean width
I know lot of fast guys (non-Schumacher) cut around 2mm off the front tires, making them 24mm wide. They say otherwise the rear tires wear more than front and handling will change during long mains, you finish with fronts bigger than rears, even though you start vice versa. I was just wondering if it's necessary with properly setup Fusion as well.
I'm hopefully going to have a test day on Saturday, so I'm trying to gather as much info as I can before that.
