Pro Circuit Pit Rugs

Give Your Pit Setup the Factory Look with Counter, Mini and Standard Pit Rugs 


CORONA, CA - April 22, 2021 - Some new accessories have arrived at our shop that will be great additions to any home garage or pit area at the race track. The new Pro Circuit pit rugs are now available in four different colorways for big bikes and mini bikes (yellow/red, red/blue, green and orange). Also available is a cool red/blue counter mat that will help protect the top of your bench from your heavy toolbox or fluids.


Our new pit rugs are constructed of six different layers that include absorbent materials to suck up oil, gasoline, coolant, water and dust. The polyester edging makes for a nice finish, the non-slip rubber bottom helps keep the mat in place, and finally the anti-UV layer protects the design. These rugs are also easy to clean and can be washed and reused.


Pick up a new Pro Circuit pit rug and achieve that factory setup while protecting your garage floor or the dirt from any chemicals spilling onto them.
