1.6. IOC-RACES AND ATTRIBUTION OF IOC POINTS
(a) THE PARITY PRINCIPLE - Up from 2009 there is again an equal number of international races where IOC-points (I.O.C. = International Overall Classification) can be won: 12 for wing car races, 12 for scale car races and 12 for model car races. In none of the three specialities there can be more than three races of level 1 with res. 30, 22.5, 18, 15, 12, 9, 6, 4.5, 3 and 1.5 IOC points for top-10 finishers. If there are three races of level 1 there must be also three races of level 3 where top-10 finishers win res. 10, 7.5, 6, 5, 4, 3, 2, 1.5, 1 and 0.5 IOC points. If there are only two  races of level 1 in a speciality (wing, scale or model) there are automatically only two races of level 3 in that same speciality. That also implies that there are yearly eight level 2 races per speciality if there are only two level 1 races for that speciality, and there are four level 2 races per speciality if there are three level 1 races in the same speciality. At level 2 top-10 finishers win res. 20, 15, 12, 10, 8, 6, 4, 3, 2 and 1 IOC-points.
(b) ANNUAL LIST OF IOC-RACES - At least one month before the start a new season the complete list of the 36 ( = 3 x 12) IOC-events and their level is published at the IOC web-site. [For 2009 it are the races mentioned here.] No points can be attributed if there are less than 16 racers.
(c) RACES NOT IN THE ANNUAL LIST REWARDED WITH IOC-POINTS - A race not in the list mentioned at art. 1.6.b can be rewarded nevertheless with the same IOC points as a level 3 races if there are enough racers at the start having won together 15 to 18 official world championships. They are rewarded at level 2 if there are enough racers at the start having won together 19 to 25 official world championships. They are rewarded at level 3 if there are enough racers at the start having won together more than 25 official world championships. Click here for the list with official world champions.
(d) ON UPGRADED IOC-RACES - In view of art. 1.6.c an official IOC-race of level 3 can be awarded with level 2 points if 19 to 25 official world championships were won by its entrants and awarded with level 1 points if more than 25 official world championships were won by its entrants. In the same spirit an official level 2 race can be awarded with level 1 points if more than 25 official world championships were won by its entrants.

2.2. FREE PRACTICE & REGULAR PRACTICE
(a) Free Practice time is minimum 3 hours at sprint races, 4 hours at endurance races. Free practice more than 24 hours before the race is NOT allowed. This principle stands NOT for racers club members (being at least since three months member) or members of the commercial raceway (being at least since three months member) on whose's track the race is contested. Free practice time must be equally spread over all racers (or all cars).
(b) If organised a regular practice over 8 x 3' can be added.

At all races chassis should be engraved with the driver's name and number and the body should be marked in the interior with the same number with a spot of non-removable paint or ink. At the technical control cars must be presented body and RTR chassis apart. The race director calls randomly the racers. They have to be present at the race director's stand when scrutineering starts. Irregularities have to be corrected in front of the race director. After inspection the called racer screws body and RTR chassis together.
(b) SCRUTINIZING follows once all cars are in. Non regular cars have never longer than 15 minutes to be corrected so that they meet the technical rules. Cars not back after 15 minutes are out for the race.

Art. 5: COMMON RULES AT IMCA MODEL CAR EVENTS
5.1. BASIC PRINCIPLE OF MARSHALLING, LANE ROTATION & ENCLOSED ZONE
(a.1.) THE MARSHALS -  All marshalling is exclusively done by the racers of the previous heat, the racers of the last heat being marshal at the first series.  Only marshals can touch a deslotted car. This principle doesn't hold for cars deslotting in front of the drivers stands.
(a2) MARSHALLING DURING THE NIGHT AND LOCAL LAWS ON MINORS - In several countries its NOT allowed that racers younger than full 18 years should compete during the whole night. Where such law is the case marshalling at the night section is to be done by the team mate(s) so that 6 hours of sleep is guaranteed for everybody.
(b) BAD MARSHALLING & YELLING - Putting a car on a wrong lane costs at least 5 laps. Should it be obvious that the error was intentioned the marshal is excluded. The race director has always the right to replace a too slow marshal by someone else. Yelling at the marshals is sanctioned in 3 steps by warning, 5 laps and exclusion.
(c) LANE ROTATION AT MODEL CAR RACES is done by those marshals being the closest to the cars. They change the lane stickers and put within the minute the car(s) on their new lane.  There is absolutely no work on the cars during rotation on sanction of disqualification. 
(d) ENCLOSED ZONE - On sanction of exclusion - nobody but the race directors can touch the cars in the enclosed zone. Cars leave the enclosed zone only for racing or for repairs. They are put on the track by the race directors.
5.2. RETIRED CARS & RANKING ORDER
(a) RETIREMENT - is necessary when a car is beyond repair or black flagged.
(b) RANK ORDER & RESULTS - Eliminated racers at the Consis are always classified behind eliminated racers at the Quarters. Racers eliminated at the Quarters are always ranked behind racers doing the Semis. Eliminated racers at the Semis are always classified behind racers having done the Main. However, all disqualified racers and ALL racers having been enforced to retire (due to technical problems or black flag) are always classified behind ALL racers having been not disqualified and having finished the race.
5.3. MISCELLANETOUS
(a) RACE DIRECTOR & SCRUTINIZERS - At IMCA meetings race direction and scrutinizing goes exclusively to non-racers.
(b) LAP COUNTER FAILURE - The lap counter is automatically corrected for all laps 0.2 seconds faster than the track record. In all other situations only the lap counter results are considered.
(c) CONTROLLERS - Racers can use their own controllers under condition that they are not increasing the power. Controllers must be mass produced and available in large quantities on the market.
(d) TRACK CALLS - Only allowed (i) on debris in the slot, (ii) on power failure, and (iii) on non-marshable car(s). Any non-authorized track call results in a 3-lap penalty on behalf of the caller.
(e) LOW VOICE - On the same sanctions as sub art. 5.1.b the race direction may hear at model car races from the racers no other words than "Double!", "Under the bridge", "My car on ..." at too slow marshalling, or "Track!" on track call. Yelling and shouting are strictly forbidden!
(f) BALLAST RULES - Ballast rules as in art. 3.3.e, 3.4.e and application at the Procar BMW M1 Races can be abolished by the race director on request of one or more racers having not finished in the top-3 of the previous rounds.

Mixing of chassis parts between different manufacturers is allowed. Assembly of chassis parts must be done via bolts and/or glue using to the original holes provided in the chassis. Positioning of the parts is free. Except for the (i) bolts, (ii) nuts, (iii) spacers, (iv) washers, and (v) braids no other parts of the chassis may be used than those mentioned in IMCA's Exhaustive List with Homologated Parts. This list will be updated twice per year. Using pieces of obscure shops or existing only for one racer or a small group of racers will be stopped in this way. IMCA is strongly opposed against all attempts of frustrating and unfair racing at the Worlds. (2) CHASSIS PARTS - All chassis parts (other than those mentioned sub art. 6.B.4.3) 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. Beside the legal modifications (see art. 6B.4.3) all changes on the chassis (as soldering, drilling or cutting etc.) are NOT ALLOWED in all forms and kind of variations. The use of legal optional parts is FREE of choose. (3) ALLOWED CHASSIS MODIFICATIONS - Allowed  modifications: (i) adding of ballast, (ii) spring plate and springs  (iii) the H-section, (iv) body mounts/holders, (v) the front axle holder, (vi) the guide, guide nut and guide holder. All those replacement items are limited to what is clearly mentioned in the IMCA list. (i) 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. (ii) SPRING PLATE & SUSPENSION SPRINGS - Chassis Suspension Springs are ALLOWED to use. The springs must be those in the list and used in soft, medium or hard tension.  The spring plate may be of any make if homologated. Carbon spring plates are allowed when they belong to homologated chassis part list. Replacing the spring plate by a separate front and separate rear suspension as on the Fola MkIV chassis is allowed. (iii) H-PLATE BODY MOUNT - The body mount subframe („H“-plate) may be of any homologated chassis parts in the list and may be made out of carbon. (iv) PAIR OF BODY HOLDER PLATES - Original body holders may be replaced by carbon lightweight holders of any homologated product in the list. There is always a single holder per side, but the same type must be used on both sides.  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. (v) 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 NOT ALLOWED. For lowering the front chassis one can use part PF.3304E2. (vi) GUIDE HOLDER - The original guide holder may be of any make and be made out of carbon. 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 from those on the list. Contact fluids to add on braids (for example MURA “Tiger Milk”, SLICK 7 “Voodoo”) are ALLOWED for use. (4) MISCELLANEOUS CHASSIS RULES - (i) All modifications, other than the replacement by carbon, resulting in a lower weight, are NOT ALLOWED. Chassis components (including motor mount bracket) are ALLOWED to be adjusted and to fine sandpaper the surface for an extra perfect fit.  (ii) The use of SIGMA security nuts (SG.8713), fine spacers (SG.8225, SG.8226, SG.8227) and SIGMA wheel stoppers (SG.8220) is ALLOWED. (iii) The front and rear axles are free to choose from those on the list as long as they are made of a single piece solid steel, titanium or carbon with an outer diameter of 3mm. Thus: only ONE front axle, not two short parts (camber fronts are NOT allowed). (iv) The use of heat absorbing paste etc. is NOT ALLOWED. (v)  The opening for the motor in the ground plate may be closed by any piece of any make. 6.B.5.

SANCTIONS & PENALTIES ON PORSCHE 997 GT3-RSR SUPERCUP CARS (a) UNAUTHORISED TYRE DRESSING- Unless specifically allowed by race direction any form of tyre dressing on handout rear wheels results in disqualification.  On mounting the rear wheels, under the eyes of the race direction, it's allowed to use the green voodoo (but only the one given by the race direction) to make the rear wheels softer. (b) ON TYRE CHANGING AT ENDURANCE RACES - New wheels must be mounted in racing time. The competitor can re-enter their car only after inspection. Non respect of tyre change - obliged at least at mid-race - results in loss of 10 per cent of achieved laps. (c) ON ILLEGAL BODIES - If a car is presented at scrutineering, having not respected all rules concerning the body, it is at the race director's discretion how many ballast should be applied to the body at the highest point under the front bonnet.  (d) SANDING- Any sanding or dremeling of the body or the wheel arches will be sanctioned by minimum 2 x 15 grams extra weight to be glued into the highest point of the bonnet and highest point of the boot. If the dremeling was hidden and well intended to skirt the rules, exclusion will be the sanction. Cheaters are not welcome in IMCA racing.

    MASS MANUFACTURED CHASSIS
Appendix  J: ON MASS MANUFACTURED CHASSIS
J.1. GENERAL DESCRIPTION
DEFINITION -  Beginning a new season IMCA's Technical Division publishes a list of all available chassis being considered as mass-manufactured. This list can be found here. The list will be published twice every year. Any chassis in this list is considered as a mass-manufactured chassis. Any other chassis NOT in this list can only be considered as "mass manufactured if all clauses in art. J.2 are respected. If this is the case the chassis will be added in the course of the year to the list, but NEVER LATER than 3 months before the start of (a) the IMCA Worlds or (b) of the European Endurance Championship.
J.2. CONDITIONS FOR HOMOLOGATION OF NEW CHASSIS
(a) REQUEST FOR HOMOLOGATION -  Any manufacturer and/or distributor is allowed to enter a demand for homologation of a not already homologated chassis. Request is done by e-mail to raymondvc@slotracingmerlijn.be. Without request for homologation no new chassis can be allowed in IMCA racing.
(b) ELEMENTARY CONDITIONS - The proposed chassis must (i) be adjustable in height, must (ii) have 6mm openings for front and rear axles, (iii) must provide all pieces except the guide, guide nut, axles, wheels, gear, and pinion, (iv) must be built in such way that the IMCA homologated motor can be fit to it exclusively by screws. If those elementary conditions are not respected homologation will be impossible.
(c) ADDITIONAL CONDITIONS - (i) The new chassis must be world wide commercially available via an e-commerce or be available via the most important distributors in Germany, the USA, Canada, Japan, South-Africa and Australia or New Zealand, (ii) must be available the three last months preceding the IMCA Nats or the first round of the IMCA European Championship at so many copies as there are entered cars with a minimum of 50, (iii) may never cost more than the double of the price of the chassis having won the last world championship.
J.3. HOMOLOGATION PROCEDURE
(a) HOMOLOGATION COMMISSION - Immediately after request for homologation the Commission must receive two copies of the new chassis to be sent to Freezslot p/a Willy Heerwegh,  Henri Werriestraat 15, B-1090 Brussels. The two chassis will be studied by the homologation commission, making a report upon it.
(b) HOMOLOGATION REPORT - In the homologation report the homologation commission has to stipulate the reasons why a new chassis is yes or not accepted for homologation. The homologation report must be sent by e-mail to the IMCA president.
(c) DEFINITIVE HOMOLOGATION - Only if the IMCA president accepts the homologation the new chassis will be added to the list of homologated cars. As long as the IMCA president did not approve the homologation the new chassis will not be accepted at IMCA racing, except for races where experimental chassis are allowed.
(d) DATE OF HOMOLOGATION - A new chassis is considered as homologated up from the moment it appears in the list of homologated cars.
