#The Chassis ground plate SC8401 cannot protrude more than 2mm from the widest point of the body also no more than 2mm in front of the side pods when viewed from above. Consequently it is allowed to modify the ground plate to fulfill the regulations.

These races are for the Scaleauto Audi R8, BMW M3 & Z4, Jaguar XKR, Porsche 911 RSR, Viper GTS-R and Mercedes SLS GT3. These races are open to all versions of these GT2/3 cars. Including the white kits released by Scaleauto. If using a white kit all major parts must be fitted as on the Factory releases. Small parts such as winglets and mirrors may be omitted as long as the car body meets minimum weight.

All of the body parts that come with the allowed models as described above must be used. All parts must be fitted on the car and in the correct location. Only exceptions to this is small parts previously mentioned such as mirrors. Inner fenders where fitted must be in place.

Scaleauto and Scaleracing are determined to create a new philosophy for Model Car Racing in 1/24 th scale. A form of racing where the Racer not only desires to perform but also understands it is critical to protect his car from damage. To that end, major body parts must remain fitted to the car at all times during racing. Any repairs MUST BE DONE UNDER “GREEN” CONDITIONS. The track will not be turned off, nor the race stopped to allow a crashed car to be repaired no matter who caused the damage. Drivers must not Marshal cars, and all cars will only be allowed to Pit from a predetermined “Pit area.” All work on cars will be done at the Pit Table in full view of the Race Director; any car worked on in any other area will be disqualified from the race.

This includes braid, braid clips & lead wires, axles, bearings, wheel inserts, spur gear, pinion gear. Scaleauto braid may be soldered into the brass connector to prevent falling out during racing. Axle spacers may be trimmed to allow correct wheel spacing. At no time (including float) may wheels or tires be visible outside the body when viewed from above.

Early cars can upgrade to ball bearing on the axles. SC-5100 and SC-5118 locking nuts are allowed as well as T Nuts SC-8126A, B, C, D, E, G, H and I to mount the H Plate, and you may tune height on the plate with Scaleauto axle spacers, or similar washers if these are not available.

All bodies and interiors must be painted. The minimum weight for the body with the body mounts and fixing screws attached is: 58 grams for all body styles. The actual body may not be modified, the Scaleauto lightweight parts may be used on all cars running the SC-8000 chassis version of the cars, to lower the weight.

Caution, at no time can a car run on track without the rear wing fitted in the correct position. Any car not Pitting under “ GREEN” to immediately fix a lost or misplaced rear wing will not be scored while run without the wing. If the car continues to run after warning lap counting will stop until the wing is fixed.

You can also use Shoe Goo to strengthen the front and rear of the car. Also the side mounts where the body attaches to the chassis. You may also use Shoe Goo to strengthen the fit and mount of the interior. But you may not use Shoe Goo, or any other product to weight tune the body. Any questions on this will be addressed in technical inspection.

It is legal to straighten the chassis and other metal parts. You can also clean up flashing or burrs on parts but cannot file to change the height or shape of parts. Countersinking holes lightly is allowed redrilling or resizing holes is not.

The chassis and chassis to body mounts must be assembled in exactly the same way as the “STOCK” technical samples. This does include position of axle mounts. Guide lead length and position of the body on the chassis mounts may be adjusted. You may also adjust the wheelbase as long as the body is not altered in any way and that the wheels are centered in the wheel arches.

Stripped screw holes may be repaired with stud or loctite type products. One area where we have seen damage is motor mounts, it is permissible to countersink the underside of the chassis and mount a screw up to repair/replace the stock screw down into the chassis for motor mounts. We then advise using Scaleauto lock nuts on these mounts from above.

The length of Scaleauto guide blade can not exceed 29.00 mm. There are several different guide nuts manufactured by Scaleauto all are legal, non Scaleauto guide nuts are not legal. All Scaleauto guides are legal, no modification other than trimming for slot depth.

This includes the profile of the guide, this cannot be altered. You may tape down lead wires, but must use Scaleauto appearing wire, guides, nuts shims are allowed . Only one guide blade may be used to locate the car in the slot. No other part o f the car may protrude into the Slot at any time. The guide depth may be trimmed if required to prevent hitting the bottom of the slot. Only the minimum needed to prevent this will be allowed. (This measurement can vary from Track to Track and will be decided at the Events)

This includes after a crash, if any part of the car is lost to allow the chassis to be visible it must be repaired immediately under “ GREEN” track conditions at the Technical table. (no work will be done when track power is off for lane changes or any other reason)

Front wheels and tires may be “STOCK” Scaleauto as supplied on the approved cars. The minimum outside diameter of the tire at the beginning of the race shall be at least 26.00 mm and minimum width of 10.00 mm. Scaleauto Foam front wheel/tire combinations SC-2715 may be used. These are supplied 26.5 mm with 8 mm width. The width may not be modified nor profile of the tire changed minimum height 26 mm.

Once Rear tires have been handed out the car and all tires are under Race Control, tires must be fitted at the Technical table then handed in to Race Control. Anyone removing their car from race control after fitting their motor or tires will be disqualified.

Motors can be spec’d by Event organizers, Scaleauto motors only are allowed. At National Finals hand out motors may be used. Another way to spec the cars is to Dyno cars prior to the race; this is decided by Event organizers and should be announced before the Event.

Under compression the chassis must still clear the track by at least 0.5mm. This dimension will not change during the race as front tires do not wear. If due to a crash clearance becomes lower the car must be repaired before re-entering the race.

This is to protect the track surface, make sure your car complies as early Scaleauto GT3 chassis cars came with the front end too low, you can not use the SC-8147C or SC-8147D front axle brackets. Also T Nut above 4 mm may fail tech, it is up to you to make sure there is clearance at all times.

You can use the tuning springs on the floating front end, but make sure you comply with the clearance rules. Under no circumstance will a car be allowed to run with less than clearance, nor with less than 0.5 mm on the front end under full spring compression.

The SPIRIT of these Rules are to run a fair and competitive Event where all feel they have a chance to succeed. This is a test of the RACER’s more than the car, and while Set Up is important racecraft and tactics are a big part of this Event.

While the Race Organizer and Race Director will do all they can to enforce the rules we call upon the Teams and Racers to help make the Event run fairly, if you know of an infraction or need to clarify a rule please do so by filing a public protest.
