Finally, we put into production the weight plate system we have used in pro racing for a long time!

4 studs thread on to the passenger seat mount, and you can add up to 250 lbs! Mount  your cool box on top if you want!

• Assortment of weights comes  with the kits. 
• The 100lb kit comes with  
  • 3x 25lb plates
  • 1x12lb plate
  • 2x6 lb  plates
• The 200lb kit comes with
  • 6x 25lb plates
  • 2x12lb plates
  • 4x 6lb plates

Each plate is hot rolled steel and painted to keep cost as reasonable as possible. The downside of this is the cost, the positive is that you only have to buy it once, and its a lot safer than bolting random pieces of lead in the car, or even worse, tucking some brake rotors in a blanket behind the seat.... We are guilty of that to make weight in close races!
