Mark, from the rule book on IMCA's site:
Article 6.5 (F430) and 7.5 (GT/LMP)
(d) ON CAMBER FRONTS - Inclination may never be more than 3°. The inner side of the complete wheel may be lower than the 25.5 mm sub art. 6.5.b, but
only to make that the tire is flat on the track over the complete 5 mm. Seen from above wheels must be covered entirely by the body.

FERRARI F430 TECH RULES -- FRONT WHEELS
So that means that the maximum spur is 78, no mather where it should be measured. that's why I'm afraid people will not pass TC, cause the inserts
will make them measure 78+....
Still waiting on some 'official' IMCA replies  Maybe they can shed some light in this dark rulebook. like on the wheelfenders on the front, I've seen many variations in interpreting this rule..
Big holes in them, narrowly cut.........

FERRARI F430 TECH RULES -- FRONT WHEELS
If the Rulebook says 78mm wide, then everything, including Inserts, must be within the 78mm wide measurement. if yuor inserts stick out the rims, then
your wheels have ben narrower, so that they fit within the 78mm wide limit.. Simple.

but because of course I wanna run on 78, I'll have to put the inserts deeper into the rim, which is f*ckin' ugly!

FERRARI F430 TECH RULES -- FRONT WHEELS
It looks like the IMCA rule book needs some further clarification:
With cambered fronts, where will you measure the spur width? I assume where the wheels touch the ground/tech block/track. Please confirm and/or update
the rule book.
Spur width and F430 inserts continued: technically the inserts have no function other than cosmetics. I would suggest to measure the width on the rim
only, ignoring the inserts which might stand out of the wheel.

FERRARI F430 TECH RULES -- FRONT WHEELS partII
Hello dear sloters
I propose to not measure the front spur width. Instead, view the car from above and ensure nothing stands out from the wheel arches. This way there
will be no misunderstanding regarding from spur width with camber fronts and nice inserts
Merci à J-M Tillen pour la traduction

FERRARI F430 TECH RULES -- FRONT WHEELS partII
I do not have a car here where I am at the moment but i do believe that the F430 is actually only 78mm wide.
If that is correct, and the Rule states that the body must cover the wheels completely, means that if correctly built, there is no way that the Spur
can be geater than 78mm....
I Stand corrected. The body is 79,5 wide outside and inside the fenders, 78mm but you need about 0.8mm-1 mm free space between body and wheels per
side meaning that you will not exceed the 78mm limit.
It is also obvious that the spur will be measured at the widest point.

FERRARI F430 TECH RULES -- FRONT WHEELS partII
I agree with Fola. 
It's really impossible to get the spur any wider without "modifying" illegally the Fujimi kit.. So, I can't see how there can be any problems
here..

if you run with cambered fronts you can still be 79,5 wide and have clearence between body and wheels.
only correct thing is a max. size in mm. and offcourse measured on the lagest point (on cambered at the track) so 78 mm. is good for both cambered and
non cambered wheels.
and I go for Gabes proposual, dont measure the inserts, it dosnt have any influerence on the race, put them on the cars so the cars any most beauty.

One thiong we've ALL missed, (well I did), is the rules say the Front Wheel Arches MUST BE USED!!! That takes away a lot of the "play" between
wheels and body, as we have to use the plastic Front wheel arch part which comes in the standard kit... These things will look like 4x4's soon, nose
up in the air...
I think that rules out Ind Fronts.. Straight setup will provide more clearance.
Anyone else ???

Hi Al,
I have been through the F430 rule set so many times my eyes are getting buggy. Can you please quote the Art.No. in the rules that says the
front wheel arches must be used . . . because I don't see it. The front wheel arches on the sprus are a part of L1 according to the kit in
my hands . . . which is NOT listed as a required component in Art. 6.6. Unless this is some type of a twisted SA dodge to get us all bulding a
Maranello version of the Hummer.

Hi Mark,
I'm afraid it's right there dude..
(e) INTERIOR UNDER FONT BONNET - Part L1 should be cut so that the front wheel covers and the base of the dash board are maintained (all the rest may
be removed ). The front fire wall may be cut such that the chassis can pass.
Having completed mine, I find I've still got good clearance, so it's all ok for now..
Chhers

Hey Al,
Now I see it. Don't like it . . . but I see it . . . still shaking my head. I think it would be better for everyone if there were pictures in the
rule set of the parts that need to be 'cut or modified' . . . as there is a bit of interpretation to be sure. Better go back downstairs and look
for the razor saw. Thanks for the heads up all round . . . and a pint on me!
Mark

The most active photo publisher is certainly Fola . Check out his
F430 album at http://picasaweb.google.de/fola.osu/430
Checa you can upload picture (not larger than 800x600) via Attachment or link to it using the HTML code "open angle bracket (less than sign)img
src="--URL to your picture--" /"close angle bracket (greater than sign)
[EDIT] apologies for the confusion - should have asked Fola first and not post incorrect information  - and thanks Fola for the very nice and detailed pictures you've posted below [/EDIT]

The pic I show you is with other reference of F430.

Why do front wheel arches have to be used?
I do not get it? Why is chosen in the rules that we have to use the front wheel arches? For what reason? I have never seen it before in any rule book
so far.
