Sprite Proxy Race 2018 - Rules and Guidelines

[VTECFOUR]

The Sprite Proxy Race celebrates sports car racing of the 1960’s in its simplicity and ingenuity. In that spirit, the following rules and guidelines strive for period appropriateness in the modeling and performance of the day.

Overall
The provided hand-out parts including the body, wheels, tires and motor cannot be modified unless otherwise stated in the following guidelines.

Body
1. The provided Bug/Frogeye body must remain stock on the exterior as provided in the kit. No chopping or sectioning of the body to lengthen, widen or shorten it. Sill height must be maintained. Wheel arches cannot be re-radiused but can be cleared of molding flash. Removing flash from incomplete molding within the driver cockpit and rear valence detail (muffler, gas tank) is also allowed. The inside of the body can be sanded or shaved to reduce weight but must not be penetrated. Conversely, resin or epoxy may be added to reinforce thin areas.
2. The Bug/Frog-eyed "face" must remain intact including the grille and headlight pots. The grille may be opened to the original shape and be filled with a mesh material. Headlamp bezel and lamp detail not present on the provided body may be added.
3. The hard tonneau cover and driver upper torso on the provided body may be removed and replaced with a soft tonneau cover or interior tray and replacement driver figure. The figure must include a head with shoulders, arms and steering wheel. Open faced helmets are encouraged for a period “look”.
4. Cockpit must be covered so that the chassis/motor is not visible when viewed from above.
5. A roll bar or head rest fairing must be installed. A windscreen is optional and can be any shape or material. Mirrors are also optional.

7. Car must be painted in a period-appropriate color scheme and clearly show the car number in three locations: both sides and the front bonnet or rear deck.

2. A single guide may be a keel or pin type. Depth is limited to .275 inches (7mm). For a keel, length is a maximum of .710 inches and must not extend past the body when viewed from above.
3. Wheels used must be the provided RS Slot Racing RSW002 aluminum rims, front and rear.
4. Car must roll on the provided Paul Gage urethane tires 21073 at the front and 21093 on the rear. They may be glued to the rims, sanded and edge-rounded to a minimum diameter of 20mm.
5. Wheels must have inserts (.450” diameter), preferably period-appropriate.
6. Wheels and mounted tires must fit within the provided body and not protrude beyond the fenders when viewed from above.
7. Wheels and mounted tires must be fully visible in the wheel arches and not be tucked and dropped within the body.

There's been an amendment for the tires in the Chassis and drivetrain section. To help clarify, the new guideline is:

4. Car must roll on the provided Paul Gage urethane tires 21073 at the front and 21093 on the rear. They may be glued to the rims, sanded and edge-rounded to a minimum diameter of 20mm.

It was previously stated that tires could be "lightly sanded" which turned out to be too open for interpretation. This is a measurable way of what is allowed.
