I know it sounds like a stupid question, but i just watched Beam.Ng Drive vs. Real Life and when I Saw the Subaru Impreza vs the Hirochi Sunburst, the Sunburst's bumper just came off when it hit the barrier. I've also experienced with the bumper falling of at slower speeds. And this goes to the SBR4, ETK 800, And the K series?(Haven't really drove around with the K Series. The other cars, the bumpers are fine. But for those 4(or 3) cars. I really want it fixed.
