At just over 1.4 pounds and compact dimensions, it's portable and won’t add much bulk to your vehicle. Safety and reliability have been key focuses since it’s built for high-performance conditions on the track. This product is quite specialized for racing use and may not be the best fit for everyday vehicles or casual use.
