Limited Drag Radial, aka LDR, is one of the best door car classes in drag radial racing. With a maximum tire size of 295/65/15 they look like a normal car and are identifiable. In fact, the rules are very particular on the body of these cars, requiring stock quarter panels, all factory body lines, and more. Composite panels are allowed for some of the body parts, but they must have the stock shape and size for the body being used. They can’t have wheelie bars, must use stock front frame rails, and are required to stay with stock wheelbase, +/- 1 inch.
Competitors are allowed a variety of engine combos, with the power adders of their choice, and all engine and power adder combos have minimum weights in the rules. This class has been around for a long time, and the rules are very well scienced out.
In the video below you’ll see some LDR racing action from the US Street Nationals at Bradenton Motorsports Park, along with some of the resulting carnage. Ouch.
