SMJ Twister Rear Bumper Side Stiffner

SMJ has released a stiffener to help reduce the chance of rear body tucks during race accidents that is intended for use on saloon car bodies from Xtreme Aerodynamics.  Pre-cut to fit the Twister and Twister Speciale bodies, it comes with double-sided tape so it can be easily attached to the body.
