Art. 2: PRE-RACE CONDITIONS AT ALL IMCA-EVENTS
2.1. TRACK CONDITIONS
(a) AT MODEL CAR RACES - All racing goes on clean tracks without the use of any glue. Voltage will be limited to 14.2 Volts
and may be never lower than 13.6 Volts. This voltage is to be measured unloaded, using accurate digital voltmeters to record the values.
(b) NOTE ON SAFETY - Most cleaning solutions are flammable! Care must be taken during their use.
Other necessary precautions should be taken to insure safety.
2.2. FREE PRACTICE & REGULAR PRACTICE
(a) Free Practice time is minimum
3 hours at sprint races, 2
hours at endurance races (less cars).
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'
or
8 x 2'
can be added.
2.3. REGISTRATION, SCRUTINIZING & ENCLOSED ZONE
AT MODEL CAR RACES (a) REGISTRATION
- All cars shall be inspected and impounded prior to qualifying and after fining entry fees
by an official IMCA scrutineer. No cars will be accepted after announced registration closing time.
Closing time is the same for all cars.
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.
(b)
SCRUTINIZING follows registration
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.
(c) ENCLOSED ZONE - Immediately after scrutinizing all model
cars remain in the enclosed zone where no work is allowed, except at the
race director's discretion. Cars leave the enclosed zone only for racing.

AT
ALL
IMCA-EVENTS
3.1. QUALIFICATIONS
(a) ON QUALIFICATIONS -
Organiser decides upon the type of qualifications. If organised, qualifications go in
principle over (i) one minute per car, or (ii) over 8 x 2' or 6 x 2'. Only the fastest lap is
considered. (b) QUALIFICATION ORDER
- Order follows the rank number of the racers,
with the best ranked racer starting as last.
Rank numbers are based upon the IOC-list of January 1. If there are two or more
racers per car
one adds IOC-points of all racers on the same car. The car
with the highest score starts as last, [or in the last heat on qualifications of
type (ii)] the car with the lowest score as first
[or in the first heat on qualifications
of type (ii)].
3.2. RACE FORMAT AT SPRINT RACES
(a) AT THE IMCA 124 MODEL CAR WORLD CHAMPIONSHIP - Composition of the heats at
Consis, Quarters and Semis is based upon the rank numbers. Racers with the
highest rank numbers start always first, racers with the lowest rank numbers
last. Racers with a rank number from 1 to 8 are always free from Consis and
Quarters. Moving up is only based upon achieved laps (Jozef
Miskolci clause). (b)
AT THE MELLO YELLO FOR KIDS - Only those 8 or 16 kids having scored most points at the
preceding Franco Gianotti Trophy can enter the 8 x 3' main final. (c) AT THE
MELLO YELLO FOR AMATEURS - Only the 8 amateurs having scored most points at the
preceding Franco Gianotti Trophy can enter the 8 x 3' main final.
(d) AT THE FRANCO GIANOTTI TROPHY - Per round there are only heats with the
racers with the highest rank number in the first, and racers with the lowest
rank number in the last heat. For BALLAST RULE: cf. art. 3.3.d.
3.3. RACE FORMAT AT EEC
(a) IMCA RECOGNITION -
The EEC 2008 as trusted by Tamar Nelwan - working without
independent race direction - is, up from round #3, no longer recognised as an
official European Championship.
It will be considered as the
EuroCup. An official European Championship, with 2008 FIA GT cars, will be
organised towards the end of 2008.
(a) NUMBER OF ROUNDS -
IMCA's president decides over how many rounds and events the EEC has to go.
That's never more than 4 events and 5 rounds. (b) POINTS SYSTEM
AT THE EEC - At each round the 8 first in class
GT1 or LMP1 and the 8 first in class GT2 or LMP2&LMGT win res. 20, 16, 12, 10, 8, 6,
4 and 2 point.
Three top qualifying cars in each class win res. 2, 1 and 0.5 extra
points.
(c) STINTS - No racer can do
more than 15 stints on 24 segments at endurance races. (c) OBLIGATORY REAR
WHEEL CHANGE AT BENELUX CUP - cf. art. 1.4.b (d) OBLIGATORY EXTRA
BALLAST OR POWER RESTRICTION RULE - The 3 first of each class at each race have to start with res. 15
gram ballast, 10 gram ballast and 10 gram ballast to be glued
under the highest point of the front bonnet.
3.4. RACE FORMAT AT ENDURANCE WORLD CHAMPIONSHIP
[NEW!]
(a)
LIMITED NUMBER OF CARS - 16 FIA GT or LMS cars as described in art. 7. (b) THREE RACERS PER CAR - In principle there are three
racers per car. Top teams can never exceed that number of racers. Other teams
can ask a wild card for a fourth racer. Wild cards can only be allowed for
racers who subscribed before the expiration date. (c) POWER RESTRICTORS - In
principle power restrictors of - 0.6 Volts can only be obliged for cars wider
than 88 mm. It's at the discretion of the race direction if this rule will be
applied. If it concerns teams where one of the drivers (or both) collected
more than 150 IOC points use of power restrictors is obligatory. (d) TWO CLASSES -
On racing FIA GT cars GT1 cars and GT2 cars are raced apart. GT1 cars go to pros, GT2 cars to
semi-pros and amateurs. On racing LMS cars LMP1 cars go to pros, LMP2 & LMGT
cars to semi-pros. The winners in GT1 or LMP1 are official world champs pro
endurance racing, the winners in GT2 or LMP2 & LMGT world champs semi-pro endurance
racing. Both groups do a non-interrupted race of 12 hours (3 x 8 x 30
minutes with 1 minute for automatic rotation). (e) ON STINTS - The first
racer (who is supposed to assemble the car) and the second racer have to do each
9 stints, the third racer 6 stints. If there are 4 racers they have to do all
four 6 stints. Non respecting this rule costs a 10 per cent lap sanction. (e) TYRE CHANGE - Rear tyres must be changed in front of the
race direction during the first segment after mid-race. Teams receive only fresh
tyres when the old tyres came back. No change results in a 50 laps penalty.

FIA GT & LMS CARS
TECH RULES
|
Art. 7: FIA GT CAR SPECIFICATIONS
7.1
GENERAL DESCRIPTION
(a) FIA
GT CAR - Any copy at scale 1/24 or 1/25 of a race car having seen in the FIA GT
series of the current or the previous year will be considered as a FIA GT car
under the restriction that the body is available on the market in at least 10
copies. (b) LMS CAR - Any copy at scale 1/24 or 1/25 of a race car having
been seen in the LMS series or the Le Mans 24 hours of the current or the
previous year will be considered as a LMS car under condition that at least 10
copies are available on the market.
7.2
WEIGHT, DIMENSIONS
& GROUND CLEARANCE
(a)
WEIGHT - Minimum for a FIA
GT car of Type GT1 is 210 grams, for a GT2
190 grams. Minimum weight for an LMS prototype (LMP1 ànd LMP2) is 210
grams; for an LMS grand touring car of type LMGT1 minimum weight is 200
grams, for a grand touring car of type LMGT2 minimum weight is 190 grams.
The former weight calculator as used at the EEC series, being not scientifically
based and pure empirical, will no more be applied in IMCA racing.
(b) DIMENSIONS - Dimensions of FIA
GT cars and LMS cars are those of the manufacturer under condition that scale is
precise with a degree of tolerance of
4 per cent.
for height, width, length and wheelbase. Racers showing with an incorrect model
using excessive dimensions (e.g. E.Jan's Maserati MC 12, Cursa's Saleen S7R,
Slotfactory's and Spark's Aston Martin DBR9) will have to add under the highest
point of the bonnet an extra ballast of 1 gram per per cent
of the highest difference.
Example 1:
the E.Jan Maserati MC12 is 12 per cent too low. Difference of 12 - 4 = 8 means
that 8 gram ballast must be glued into the highest point of the bonnet.
Example 2:
Cursa's Saleen S7R is excessively low (40 mm instead of 43.4 mm), that's a
difference of 8.6 per cent. Difference of 8.6 - 4 = 4.6 implies that 5 gram
ballast must be added under the highest point of the Saleen.
Example 3:
Slotfactory's Aston Martin DBR9 is 45.5 mm high where 49.79 mm was
required. That's a difference of 9.43 per cent so that 5 gram ballast must be
glued under the highest point of the bonnet.
Example 4:
Spark's Aston Martin DBR9 is 46 mm high where 49.79 mm was required.
That's a difference of 8.24 per cent so that 4 gram ballast must be glued under
the highest point of the bonnet. Note: Model Factory Hiro's DBR9 has the correct
dimensions.
(c) DIMENSIONS CONTROL - Before the
start of a race IMCA must provide the race director and his scrutineers an
exhaustive list with the four dimensions (L, H, W, wheelbase) for any car at the
start, so that occasional ballast can easily be calculated.
(d) GROUND CLEARANCE in FIA GT
racing or LMS racing is at least
1.2 mm,
starting the race
and may be never lower than 0.4 mm.
7.3
CHASSIS, MAKE & TYPE
Any mass manufactured
chassis is allowed under the strict condition to use no other parts than those
of one and the same manufacturer. Free materials are restricted to (i) nuts,
bolts, spacers, washers and springs; (ii) braids & lead wires; (iii)
motor holder, (iv) body holders, (v) axle bearings and (vi)
ballast weights.
7.4.
