The flagship brand of Ambit. We brand all our latest and greatest flow form wheels this brand Doss Wheels. Flow Form is far superior than the convention cast wheels, for just about 20% more in price, you're getting a wheel with the most modern manufacturing technology, that is lighter, stronger, and better than the standard cast wheels. The lighter wheel results in less un-sprung weight, which equals to greater fuel economy, but more important, greater handling both on and off the track. Flow Form is the new standard for wheels today, most 18/19 inch wheels in this category all land in the 20lbs range, which is much lighter than the stock wheels that come equipped from the factory. We highly recommend looking into our Doss line if you are looking for a major upgrade from the stock wheels.
