Any idea why all the Muscle Cars had those tacked on brake ducts?
[quote=motorsportnerd;745490]More photos from the 2007 AMC Muscle Car Masters.
1, 2 & 3. Peter Brock's 1991 Holden Commodore VN Group A racer. After three years of racing rival marques (a BMW in 1988 and Fords in 1989 & 90), Peter Brock "returned" to Holden. Well, not officially - the relationship between Brock and Holden wasn't patched up until Brock joined the Holden Racing Team in 1994. Instead Brock formed a short-lived (one year) partnership with his former Bathurst winning co-driver Larry Perkins to run a two car team of the then new Holden Commodore VN Group A with Mobil sponsorship. Perkins built the cars and engines, Brock supplied the media image and sponsorship. The VN was the last of the Group A racing Commodores, and at the 1991 Bathurst 1000, the 4.9 litre Holden V8 had been massaged to achieve about 413kW (550 bhp) at about 8,500 rpm. They were at their limits in terms of reliability at this sort of power level, and still struggled to match the opposition Skyline GTRs.
4. '39 Chevrolet Coupe which raced in the NZ Central Muscle Cars race.
5. Interesting Group C Nissan EXA Turbo which raced in the 1983 and 1984 Bathurst 1000.
6. A Group C Falcon XD touring car which raced in the 1980 and 81 Bathurst 1000 races. The Falcons race with a 5.8 litre (351 cu in) V8 putting out about 300kW (400 bhp). This is the car in its 1981 livery as raced by Brian Muir/Peter Geohagan.[/quote]
I remember that XD from the PI trip it gets around.

IIRC in NC the original coachwork, spoilers etc from factory have to be retained but brake ducts are allowed to be fitted.
[QUOTE=whiteballz;745697]Some of My pictures. Alot are of the races and parking grounds, not of the pit displays.. Due to the fact I had the 70/300 lens on and didnt have the 18/50 with me, as I left it in the car..

That's a photo I wish I had been in position to take. I wasn't able to get many photos of the Group A/C cars. Whenever I went past the pits the Group A/C were in the pit garages (not the best location for photos) and my camera isn't the best for action shots (hence no shots of the racing).
Thank's for the photos Whiteballz:) .

Someone mustve been having a floor sale. They all look the same except for the couple of Mustangs using what look like GT350 front spoilers.

Some of those Mussies may be what used to be called sport sedans in the early 70,s I think

Body
The bodywork, fittings and interior trim in its entirety must be as supplied by the manufacturer.
Body Modifications:
Body modifications may be made, provided that the following restrictions are observed:
The inner lip of the wheel opening may be folded back for tyre clearance.
Mudguard extensions may be used if homologated.
The driver's seat may be replaced with a CAMS-approved racing seat.
The steering wheel may be replaced with a sports steering wheel of 330mm minimum diameter.
Floor coverings may be removed.
The use of under trays, fairings etc designed to improve the aerodynamic form of the vehicle are not permitted unless supplied as standard equipment for the make and model.
If brake cooling ducts or scoops are fitted, they must be separated by a minimum of 300mm, so as not to form an aerodynamic aid and their sole function shall be to assist in the supply of air to the brakes.
Additional instruments may be added providing all original instruments and switches remain intact and that additional equipment is fitted to a separate panel.
Permitted [/QUOTE]

That's only if you could deal with the awesomeness that is the Holden 304 :p

Pretty good photo, How many groups are there anyways
About four or five diferent groups of racing.
Well before Group C i think it was something like Improved Production, before that it was something like modern day Group N where they raced homologated cars like the GTHO's, XU1's and Chargers. Theyre not all necessarily designated Group "X"

Neat photo of Big Norm Beechey circa 1968 in the metallic blue 327 :cool:
Jesus those things stick out like dog balls. Im surprised actually Ford Holden and Chrysler never incorporated them in their homologation specials. They gave them the huge fuel tanks and a few other endurance liberties afterall.

The Cortina GT500 production cars of 1965 do have them as stock fitment, albeit in a more subtle version. Positioned discretely underneath the front pan so mostly hidden from view and its hard to find decent pics
EDIT did find a photo for you FPV but it won't upload for some reason :(
Muscle cars was great may get back there this year to race the Exa i hope!
You're the owner of the ex-Nissan Australia Group C Exa Turbo?
