slowhand: Just came back. On the way out I was thinking about the lowered CG. I do not feel it is lowered; the CG of the car is about the chassis right? So even if the chassis is "lowered" relative to the suspension arms, in the end we will still need to set a ride height.
Let's say for a 5mm ride height, no matter how the suspension arm spacers are placed, won't the CG still be the same? The front/rear roll centre (ala roll axis) will be affected, it will be raised higher. I can see how this could possible improve traction -> higher roll centre has high roll resistance, so the chassis will roll less in corners, though if the roll axis is too high the car could gain positive camber through corners.
Do let me know your thoughts.
ijnek: I'd say SGD$350-400? I sure would love another 414m chassis if I could afford one!
