Changes for 2023

We will be changing our Nose/Tail Differentials for 2023 in an effort to eliminate advantages smaller drivers may have over larger drivers.  The goal is to ensure that as many drivers as possible can obtain the outer limits.

For ALL Divisions EXCEPT Super Stock, the 2023 differentials will be 5 pounds.  This includes Stock, Masters, Roundbottom, and Legacy.  

Super Stock will retain a 15 pound differential because it is often impossible for larger kids in this division to meet a 5 pound differential due to the placement of the cockpit.

During the Pre-scaling activities, we will be placing stickers on your car indicating your racing position.  These stickers will enable the starter and your opponent to confirm you are loading in the car the same way you scaled to ensure you are not loading up the rear more than the allotted differentials.

If you need to adjust your race position throughout the day due to becoming more limber, you must cross the scales and have the scale master re-do the sticker.

NDR will continue to use the pre-scaling technique of recording the max empty tail to ensure the car remains within the differential limits when in race position.  As in the past, we will continue to utilize random re-scaling throughout the day based on the drawing of a scaling chip.  That scaling typically required validation of the empty tail and total car and driver.  This year we will be introducing an additional random draw chip type which would require full race position scaling.  As always, any driver or handler can request scaling for a given heat upon receiving their race wheels.  When requested, both cars will be expected to go across the scales to be validated.

All laydown divisions (Masters, Roundbottom, and Legacy) will be provided "Grip Tape" to be stuck to the floor or center weights below the drivers buttocks.  The purpose of the grip tape is to reduce the potential of shifting in the car once the hatch is closed.

A side benefit of the "Grip Tape" is that it can assist the driver during the braking process by reducing the amount of sliding that can happen while pulling a hand brake or pressing a brake pedal.

Last year we added an extra gauge to our Roundbottom inspections to validate the minimum ground clearance.  Please be advised that for complete fairness to all drivers, we will be enhancing this part of the inspection.  The clearance will be tested after the car completes pre-scaling and will be conducted with the driver in the car.  Please make sure that any Roundbottom cars brought to NDR events meet the minimum 3" clearance to avoid any disappointments and frustrations during check-in.
