I think the only point I would make about the different brands of springs is that you can't really trust their rates as advertised. So if you find balance with an AE big bore 4.20 in front you won't necessarily be able to get the same result with a Losi 4.20 spring (just an example). If you are interested in tinkering and truly learning how your car works, this is a great way to get started with it. I think a lot of people run their cars either over-sprung or over-damped on one end and the camber link mounts do next to nothing. When you actually get spring rate and damping set accurately to the track conditions, your camber link adjustments will be much more noticeable.
