Default WGTR 2024

With all due respect to the original WGTR thread. It has been determined that a new one is in order.
Thanks to Dumper and CRC for the class and the original rule set. As such I intend to carry on the intent of the class.

World GT-R Rules - Updated 5/10/2024

Chassis -1/10 scale 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 many 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!

If anyone wants to see photos of the new body list, click this link. https://docs.google.com/spreadsheets...#gid=666349674

If anyone owns any of these, I would love to add front and rear body width measurements, measured at the top of the wheel arch.

Hi gang,

Welcome to the new World GT-R thread. We would just like to thank Ron Mick for taking the lead on the rules and this forum. Thanks to all of you for the input on "our" class. Yes, it is all of ours to race, enjoy and improve if possible. While, CRC did "start" the class with the tires back in 2015, the World GT-R class is ours to enjoy and improve.

Here at CRC Raceway, we probably have the largest weekly turnout in the country. We average about 19 racers on a Thursday night for the entire season from September to May. For this past season, the largest World GT-R event in North America was 30 entries at the Canadian Nats, CRC's World GT-R Challenge race had 23, a November CRC club race had 21 entries and the Indoor Champs with 21 entries. At both the Canadian Nats and the US Indoor Champs, there were many classes offered with way less turnout than World GT-R. So, while not perfect, the class is still very popular.

As I mentioned, here at CRC Raceway, World GT-R leads our road race turnout each and every week. We have top racers, new racers, older racers and young kids in the WGTR class. Needless to say, we are very interested and invested in World GT-R. We are doing what we can to make it better, more affordable and fun.

With all of your input, Ron has done a great job with the rules and especially the bodies. He keeps it scale and real and we fully support his thinking in keeping this class in a good place with appearance. Ron listens to all the input and makes great decisions on the bodies.

The big talk in the class is of course the tires. We cannot begin to tell you the rollercoaster ride it has been in recent times and through Covid with raw material suppliers, mold makers and belt suppliers. Multiple raw material suppliers have gone out of business, other suppliers have been purchased by larger companies with different management thoughts... it has been a tough go and it all started actually before Covid in 2019. All the while, not only do we have to keep the supply rolling in, but the tires we make today, post Covid, need to be near the same performance as those we made in 2015. If we just settled and said "ooops, raw material Company A is out of business and Company B has material that is slower, can you imagine all the World GTR and Oval racers "hoarding" old tires because the new units were slower. During all these "transitions" we have had to develop relationships with new suppliers and push these suppliers to replicate the performance from the old company that is now out of business. We have done our best to keep the tires as consistent as possible despite everything making up the tire changing.

Here at CRC Raceway, we have cars competing on tires purchased this season. We also have drivers with tires from as old as 2020. Frank won the 2023 Indoor Champs with tires at least 2 seasons old. This season, he made the A-main in both the US Indoor Champs AND the Canadian Nats with the same 4 tires as he won with last year. Here at our track, we have zero issues with tires, no wear, no issues. After the fire, our track is 67 x 42, so a little short but the same width as the Snowbirds, our speeds and wear rate is similar to other tracks.

We have reports that some racers are wearing tires at a quicker rate, we are working hard to ensure the products we produce for GTR performs without any issues. We are testing and working with racers from around the world if they have any issues with the tires. It is a confusing situation because here at CRC Raceway, the venue with the MOST World GT-R entries, we have zero issues. Fast racers, new racers, old and young, we have them all here and we have no tire issues. So when we hear of trouble, we are surprised, but we dive in and try to make things better. As a manufacturer of cars, tires, batteries, etc, we have the advantage to continuously stay "hands on" with the product. We have a test track 50 feet from the office. In addition to us testing on our track, we have 50 club racers (little do they know they are product test drivers) each week coming in to race with the products we make. We see what they experience, we see problems they have. They are CRC's in house test drivers.

Why the long-winded post??? We just want to make all the World GT-R forum members aware of our thoughts and position.
** We are racers just like you.
** We are racing World GT-R every week, here at CRC Raceway with the biggest rubber tire pan car turnouts in the country.
** We REALLY CARE A LOT! We want things to be the best they can be.
** While we are not on the RC Tech forums posting everyday, we are here testing, we are racing and we really care about the class and our products.
** We are racing multiple times a week, some road, some oval and carpet offroad.
** We want to see the class grow, it is awesome; scale looks, realistic handling, affordable with tires that last, tires that are seasons old can still win National events.

So, we thank all for being part of one of the best classes in onroad. CRC has been doing this "R/C thing" for 30 years and we enjoy the class. We have many racers here at our home track and we get to watch them first hand. If there is a problem, we see it through our local racers.

Please lets all work together, make this class better. Please help Ron with suggestions and ideas. If anyone has any input or issues for us to review, reach out to us at [email protected]. Thanks to all! Race on!

@TeamCRC thank you for your continued support of the class. This is my favorite class to race and have seen it rubber band between popular and a handful of entries around the Michigan/Ohio area. Would love to see it keep going and growing.

A while back we ran wgtr cars along with pro10 cars (2s 17.5t) because of low turn outs for both classes. It was fun, it reminded me of IMSA or WEC. The pro10ís would blast us everywhere, especially on the straights. Everybody needed to be aware of the car in front and behind, making space for the faster cars, while still running your own race.

are these roar rules or simply your opinion? I think the body rules went too far. a simple stock 200 body cut at the body lines should suffice.

I've already got a car halfway built. 1s, 13.5, Ferrari 499 body, using the WIRC F1/LMP chassis, Sweep rubber tires. I'll see if people are interested in running the config with their own stuff.

Very Cool are track we normally dont run 1s 13.5. we run 2s 17.5 for both 200mm and 235mm with foam tires.

i am trying to bring back F1 to the asphalt track so both WGTR/F1 can run together i am working on buying someones rc collection so i can try a 9x8 Peugeot body on a F1 chassis and a WGTR chassis if it takes off the way i hope it could be ran year round on the asphalt and carpet track for winter season.

These are the cut and paste rules that CRC and Dumper came up with to create the class back in 2015.
The new body list added new ones and removed old ones.
These rules are guidelines for local tracks but are what are followed at major events for the WGTR class.
If your track varies from them, fine. But when you go to one of the big events this will be what you have to follow.
ROAR's rules are used for the ESC and Motors. Nothing else.
The class is intended to replicate GT style of racing around the world but on a spec tire.
