+1 on the protective sheet for the chassis. I have one on my Xray T2 009 and its been a great investment. I raised mine as high as it will go and it usually clears most debris/pavement edges... but I'm drifting, so the side of the car body often clears the way.
Raincity Raji Kon - hit me up to drift in the 206/425 -- High CS OTA-R31, RWD "doripake", 50:50 OTA-R31, Slash 4x4, Slash 2wd, Subaru Brat Scaler
