We didn't request our cart to go faster but it does, hence we have the speedometer so we can keep tabs on it LOL We did however request the bigger tires which makes a world of difference in the ride in our opinion. They are really great to deal with and we love the little custom touches they do to their carts and enclosures and as you can see by my post whatever they do did not negate our warranty at all as they did warranty work for us at N/C
