Default World GT-R Rules and Discussion

World GT-R Rules - Updated 3/02/2023

- Chassis – 200mm pan car chassis (WGT car)

-Minimum Ride Height – 5mm

-Minimum Weight – 1025 grams

-Maximum Track Width - 200mm

- Tire and Wheel Rules – CRC Part #2314 only 2021 - 2022 Rubber tire rule clarifications;

We have had some questions about the preparation and treatment of CRC rubber tires for racing. After 5 seasons of racing these tires, we have gathered plenty of data on the long term use and wear of the tire. We have tires still in use with over 4 seasons of racing on them, looking good and performing excellent.

In our experience, whether used for road-course or oval, the normal pattern of wear on a CRC tire is a slow-forming “wear ring”. This ring is parallel to the direction of travel or rotation and slowly gets deeper as the tire wears. This ring appears after many, many runs, sometimes after multiple seasons of running. Other than that wear ring, CRC tires do not show any signs of surface deformation. Under normal use, there are NO perpendicular lines or waves of surface imperfection. The tire surface stays flat. The race surface of the tire stays smooth race after race and never shows any ridges, ruffles, graininess or any “waves” of wear. We have years of experience and data on these tires. If a tire shows signs of anything but a smooth surface, it has experienced some other outside factor other than racing the tire on a carpet surface.

In an effort to keep rubber tire racing easy, convenient, more affordable and fun, we are adding a “Smooth rule” to national World GT-R rules package.

All tires presented at tech must comply to these guidelines;

** The tire surface must be smooth and free from texturing or waves.

** The tire cannot be trued, ground, filed, touched or manipulated in any way with a tool or object.

** No drills, Dremels, truing, sanding, paddling or grinding the tires. The only thing that should touch the tire is the carpet you will race on.

** The tire surface cannot show ANY sign of waves, ruffles, texture or lines. No past “shadow” texturing, or faint ghosting patterns. Smooth surface ONLY.

** No grinding the “bead” or mold line. If you feel the tire needs to be “broken in”, do it on the carpet track. Run it in practice in advance, let the carpet race track do the work.

** If you raced in the past on some kind of surface that left anything but a smooth surface, those tires will not be legal for use. Smooth surface only.

In addition to the “Smooth Rule”, normal handout tire rules are as follows;

** The tire or rim cannot be modified from the way they came pre-mounted from the factory.

** Standard inserts ONLY, no changes, alterations or replacement of the stock factory inserts. No dual inserts.

** Only the CRC black GT rim. No modifying the rim. The vent holes must remain open and un-modified.

** These are only available factory mounted, so ANY internal work is not allowed. Nothing added inside, no tape, weight, no modifications at all.

** Super glue on the sidewalls is allowed. No modifications to the inside of the tire.

** Balancing putty or tape may be added to the outside of the wheel (nothing internal).

-Battery – ROAR approved 1 cell (3.7v) hard case lipo. Voltage limit to be set by track (4.20-4.22)

-Motor – Any ROAR approved 17.5 turn brushless motor (Smaller tracks are encouraged to use 21.5)

-Rotor – ROAR approved tuning rotors are allowed

-Speed Control – Any ROAR approved spec class (blinky) speed control in “blinky” mode. NO RECEIVER PACKS. You may use a specific 1 cell speed control, or a two cell speed control with an external booster. Stock 2 or 4 cap banks that come with the ESC's only. There will be a limit of 10,000 micro farad on cap banks.

-Bodies – Bodies must be cut on the mold lines. No excessive cutting or lowering of the body is permitted. No lightening of the body is permitted. Wings and spoilers that are included with the body kits are ok if cut on one of the mold lines (if multiple mold lines are present). Wings are not mandatory. No additional aerodynamic aids are allowed. Backs of the bodies (including rear bumpers) are to be left in. No bodies that were designed for pan cars, no GTP, Daytona Prototype, IMSA, or bodies that look like 1/12th or 1/8th on road bodies with an integrated rear wing. If the body has bolt on pieces (for example the Ford GT B pillar side wings, or some of the HPI bodies have a bolt on rear bumper area), these must be used. This does not apply to the side dams that can be added to the rear wing. Bodies must weigh a minimum of 95 grams. Any weight added to the body to assist in the making of the 95 gram minimum weight must be added to what would be considered the roof of the vehicle in a non easily removed form (if you need to add weight, put some shoe goo in the roof). Any foam needed to take up space in between the body and front bumper must be added to the chassis, not the body. These rules are to encourage racers to actually put a paint job on the body and not just a spray bomb, as well as to keep some of the older heavier bodies competitive.

-Tires may stick outside the body as long as the overall width is within the 200mm maximum.

-Race Length- Have fun with this. If 5 minute qualifiers and 5 minute mains fit in your race program, do that. If you want to do 8 minute races, do that. If you want to do shorter qualifiers and longer mains, do that. We have run 15 minutes with ease. Work with your race director to fit into the program. Run time and traction are not an issue for longer races.

-Fun- 100% Mandatory!

No disrespect to the people that had started or posted in the prior WGT-R thread, but I needed a thread that I could update the first post to keep things current.

If you have any questions, feel free to ask!

I was going to convert my F103 F1 car to WGT-R specs but seeing as the mandatory CRC rims won't fit it, I guess I'm out.

The key to any class growth is low barriers to entry. The are a lot of old F103's and F104's out there in closets, not being run. Make the TIRE mandatory, but not the rims, IMHO. Let the guys bolt up the F1 wheels w/ the spec tire and boom. You have a lot of cheap potential WGT-R cars. All they need is the body mount adapter kit.

That body looks too much like a GTP style car.
