Homologations List attachment J) as supplied under ref. #PF.1700SLP (expert version) and under ref. #PF.1700SLPJ (junior version) are ALLOWED to use. All chassis parts (except ALLOWED optional parts) could be replaced only by the same original spare parts. A „mix of parts“ including chassis parts from other chassis types or made in different materials are NOT ALLOWED. All chassis mounting parts like screws (in the case of screws the longest useable cone head screw can not extend a max. length of 10mm), washers, nuts, spacers including axle spacers are free to choose as long as these parts are unmodified (e.g. the thickness of screw heads may NOT be reduced in size) standard equipment available from the Plafit range.

1.2. CHASSIS PARTS - All chassis parts (guide holder, front- and rear axle mounts, motor mount bracket, chassis main plate including „T“-bar) plus all body mounting parts (including „H“-sub-frame and mounting plates) MUST be used in standard shape as produced by the manufacturer and have to be mounted together in standard form at their original fixing points. The use of spacers etc. between the front or rear axle holders and the chassis mountings is NOT ALLOWED.

1.3. FORBIDDEN CHASSIS MODIFICATIONS - Beside the legal modifications (cf. point 1.4.) all changes on the chassis (as soldering, drilling or cutting etc.) are NOT ALLOWED in all forms and kind of variations. Optional parts allow individual chassis set ups for different body types. The use of legal optional parts is of free choice.

1.4. ALLOWED CHASSIS MODIFICATIONS - Beside the original spare parts the optional and/or tuning parts mentioned under 1.5 to 1.9 are ALLOWED to use without additional modifications.

1.5. CHASSIS BALLAST - Additional trim ballast is only ALLOWED in form of lead weight which has to be mounted on top of the chassis (including the top of the ground plate and „H“-subframe plate). All lead weight MUST be fixed in the way that no weight is extending outside the given shape of the chassis and have to be invisible from underside view.

1.6. CHASSIS SUSPENSION - Springs are ALLOWED to use only on both sides at the front fixings of the „T“-bar. The „T“-bar can be fixed with or without the use of springs (only at the front end) and/or without the use of the „O“-ring (optional for use at the front and rear end). The springs can be used in soft, medium or hard tension (#PF.1320, #PF.1320A, #PF.1320B).

1.7. H-PLATE BODY MOUNT - The body mount subframe („H“-plate) MUST be or unmodified original shape or may be replaced by the 49mm (#PF.1710), 55mm (#PF.1710B) or 61mm (#PF.1710C) body mount subframe, all or not in adjustable (res. #PF.1710T, #PF.1710BT,#PF.1710CT) form. The subframe can be fixed flexible or inflexible (rigid) on the main plate.

1.8.a. PAIR OF BODY HOLDER PLATES - Original pair of body holders may be replaced 6mm (#PF.1707B), 7mm (#PF.1707C) or 9mm (#PF.1707E) pair of body holder plates. There is always a single holder per side, but the same type MUST be used on both sides. The body holders can be formed when obligatory needed to mount the body on the chassis. Only the necessary fixing parts are ALLOWED to be used in combination with the body holders. The mount plates plus holders MUST be fixed on top of the subframe as standard equipped. The use of spacers between the mount plates and subframe is ALLOWED. Pair of body holder distances #PF.1707B2 is ALLOWED.

1.8.b FRONT AXLE HOLDERS - The original front axle holders may be replaced by the 5.5mm high (#PF.1704) or 6.5 mm high (#PF.1704B) front axle holders. Use of 3.5mm front axle holder #PF.3304 is ALLOWED. For lowering the front chassis one can use part #PF.3304E2.

1.9. GUIDE HOLDER - The original guide holder may be replaced by part #PF.1703. Genuine guide holders can be formed by bending. The guide – but only one guide per car – including fixing nut, washers, braids plus additional mounting clips (for solder on the motor wires) and motor lead wires are FREE to choose. Contact fluids to add on braids (for example MURA “Tiger Milk”, SLICK 7 “Voodoo”) are ALLOWED for use.

(f) The front and rear axles are free to choose as long as they made of a single piece solid steel with an outer diameter of 3mm.
(g) The use of additional magnets for example as „variable to fix“ chassis ballast or in any kind of other arrangements giving a magnetic ground effect (resulting in better road holding on tracks with steel power rails or magnetic track braids) are STRICTLY FORBIDDEN.
(h) The use of heat absorbing paste etc. is NOT ALLOWED.
(i) CAMBER FRONTS - The use of camber fronts is FORBIDDEN.


ART 2. MEASUREMENTS AND WEIGHTS

All races, race events and championships named DPM or named in combination with DPM or raced by DPM class, can only be raced by using the original and valid technical DPM rules & homologation lists without any change or modification.
All kinds of official use only by approval on written permission. For details please put in contact on the webpage www.plafit-racing.com.

9.3. RULES INTERPRETATION - Rules are eventually interpreted by the race organisation only and at the race day by the race director. Actual information will be published on the website www.plafit-racing.com.


NOTES

(*1) At official „ProRacing“ competition events (like „DPM“, „EPC“) all ALLOWED service materials (that means cleaning fluid, tire cleaning tape and oil) will be provided – in quantities matching the amount of lanes – from the race organiser. These materials will be available from the time of the parts handout and after have to be used until the end of the race. The use of other service materials, fluids etc. is not ALLOWED.
(*2) At “ProRacing” events new and special marked motors will be hand out free of charge to all participants just before the final free practise. Starting with the time of the parts handout only this marked motors are ALLOWED for use. In case of the need of a second engine another (also marked) motor is available in exchange from the race directors. The engine MUST carry their correct original markings during the complete race event.
(*3) At “ProRacing” series events the power supply is rated at 19 Volt (given by a separate transformer for each lane).
(*4) At “ProRacing” events new and special marked SCALEAUTO rear wheels (#SC.2421P), that means aluminium hubs complete with already glued on sponge tires of the type „ProComp 3“ (#SC.4830) will be hand out free of charge to all participants. After the parts handout only those marked rear wheels are ALLOWED for use. In case of need of a second unit another (also marked) pair of tires is available in exchange from the race directors. The rear wheel and tire combination MUST carry their correct original markings during the complete race event.
(*5) A flexible mounting glue (for example HENKEL „Pattex“ oder PLAFIT „Magic Glue“) is a glue wich can be pierced by a pin and wich is also reacts as material disconnecting by the use of cleaning- / lighter fluids (e.g. ESSO „Tiger“).
(*6) When special decal sheets are provided to the entrants of a “Pro Racing” event the race numbers and additional markings have to be applied to each car (from the begin of the first free practise until the end of the race meeting) matching the given guidelines.
