“We’ve found that a lot of the stuff on the market is overbuilt” said Spooner. “Durability is a chief concern for us but not at the expense of adding a ton of weight. We pay close attention to designing products that will hold up to the abuse of racers and recreational drivers but without adding a significant amount of weight.”

Pro UTV racer Cody Bradbury has been contesting the WORCS series aboard Grounded 4’s products and proving they have the ability to withstand the abuse of some of the nations most rugged off-road courses. Bradbury placed in the top ten in every round completed in 2015 including one 2nd place finish at round 6.
