about the springs... asking us about what springs to run is kind of like asking the dude at the video game store what game you should buy... everyone has different idea about what video game is the best. (Spilter Cell Double Agent PS2.) everyone will have a different set up for their truck. the main reason for all the different set ups is that, everybody drives a little differently, and has their oun opinions about how their truck should drive/handle. not to mention the fact that we all live in different climates, and run on different surfaces. A guy that races on an indoor clay track with perfect conditions is going to have a different take on what springs he would use compared to some one who races outdoors, on a dirt course with changing track conditions.
The track I race; in any given day, can go from rock hard packed dirt, to very dry, dusty and loose if the tempurature goes up much. On a day that is a little more humid, and cool, the track gets very tacky and grip can be had at full trigger pull on exiting a corner.
when the track is hard, I want a little tighter spring so that I can push harder in the turns, when its loose, I want a medium spring. And when its tacky and there is lots of grip, I want something a bit more soft.
As for a brand, rather than a spring rate, I see a lot of guys recommend Losi spring.
