ESR Ballast System

After seeing many of the ways people install ballast in their cars, we decided there had to be a better way. What we decided to do is to secure the weight on the passengers' side seat mounts. These mounts are designed to easily carry 200+ lbs securely. Our system comes with a steel base plate (19 lbs) that mounts securely to the four passenger seat mounting points. The weight plates (15 lbs, half plates are available 7.5 lbs) also have four holes in them, they lay flat on the base plate and attach with four 1/2 in grade 8 bolts. Weight plates can easily be changed in and out with little to no hassle. With an impact you can change the plates in a matter of minutes. This is the best system out there, it is safe, secure, very easy to use and most of all looks professional, not a bunch of bar bells or lead blocks.
