Hey guys im new to the whole forum thing. My local track is a tight indoor track and I was thinking about the CSI pistons but im not sure which color to get and what the difference between the sets are and which springs i need to use. Im currently running the stock 6x1.3 black pistons all the way around with purple front springs and yellow rears with 30w front and 25 rear all ae oil. It seems to work fine (but i may just be so use to driving it that way) but I feel like the buggy could be better in the shocks department. Any advice is appreciated.
