Look like Zoran's car in Melbourne, Australia.
I always thought Erik's car looked the best of the racers.

The white car is kinda cool-different headlight wise. A little beemer esck but I like it.
Eric, I guess immitation is flattery... or great minds think alike. Either way it's fun....
Cheers, Mike

I'm pretty sure that Zoran's lights were done some time ago so not sure who invented them?

awesome photos Eric, you all...
off topic q: for Eric, since you were nice enough to advise me where to get my brake adaptors for the best possible price a quite a while back...
_
i'm currently runnng 928 GTS 322mm front brakes on the front of my 968... does anyone know if 928 S4 304mm front rotors/calipers will fit on my rear wheels... or what adaptor would i need that could make it work.... or should i go with 928 S4/GT/GTS 299mm rear rotors or possibly 968 front rotors... and in either case, what calipers would i use ?
also... how often should i change my brake fluid ?
i also found a nice post at:
http://www.audifans.com/archives/1999/05/msg01067.html
which includes the following:
I have been quietly monitoring all the discussion regarding brake upgrades
and I feel it is time to provide some facts that seem to be lacking.
First, let me clear the confusion regarding sizes of calipers. There is only
one "Big Red" (hereinafter referred to as "BR") caliper. It originally came
on front of the 91 Porsche C2 Turbo and has been/is used on the 993, 993TT
993 GT1 & GT2 and the 93-95 928 GTS. The pad used with this caliper is 5.18"
x 2.95" with a new depth of 18 mm.
The next size smaller caliper hereinafter referred to as "S4 caliper") was
the front caliper on the 88 944TS, 89 944T, 89-91 944S2 w/M030 package,
92-95 968 w/M030 package, 928 S4 and 928 GT. To the best of my knowledge, it
was never available in red. The pad it uses is 5.18" wide x 2.8" tall with a
new pad depth of 17 mm.
Note I am only addressing the calipers sizes first. The rotor sizes will
follow as they play an important part in the brake force and balance
equation.
It should be noted the piston sizes in both of these previously mentioned
calipers are the same. The only difference is the total swept area of the
Big Red caliper. 15.28 sq. inches total swept area for the Big Red vs. 14.5
sq. inches for the smaller caliper is an approximate 5.4% increase in total
swept area.
Also important is the piston combination in the Porsche caliper is
unavailable in any other caliper from Brembo. Literally everything regarding
the Porsche caliper is unique to Porsche and Brembo's contract with Porsche
prohibits them from selling any parts etc. for the Porsche calipers. Steve's
"Ultimate Garage" page states the bolts are larger in the Porsche calipers
however I have been unable to verify this. (And believe me, I have been
trying.)
The rear calipers on all the cars mentioned above are the same size however
the piston size combination differ. As well as Porsche using different
combinations of piston sizes in the rear calipers they use different brake
pressure regulators and master cylinders to achieve the correct front/rear
brake balance.
The rear calipers were, depending on the vehicle, available in red and use a
pad size of 3.48" x 2.58" with a new pad depth of 18 mm. This pad has a
total swept area of 8.98 inches. Note this caliper with a different piston
combination was used as the stock front caliper on the 86-88 944 turbo, 944
S2, 968 and various 928 models.
Another area of confusion is rotor size. The rotor sizes for the cars
referred to above are:
Front Diameter
911 GT1 & GT2 380 mm
993TT 330 mm
993, 964, 928 GTS 322 mm
944TS & M030 upgrade 304 mm
944S2 & 968 298 mm
Rear
GT1 & GT2 I don't know
993tt 322 mm
964, 928 S4, GT, GTS,
944TS, 944 S2 (all)
968 (all) 299 mm
The BR caliper requires 17 inch wheels, the S4 caliper will fit easily under
16" wheels (depending on offset) and the smallest 4 piston caliper should
fit under 15" wheels (have not tried this yet.)
The biggest advantage to larger diameter rotors is by moving the clamping
point of the caliper further away from the center, one gets an increase in
brake leverage. Another advantage is more mass to deal with greater thermal
loads. The downside to this is larger rotating unsprung mass which
ultimately affects both acceleration and turn-in.
I have experience with all three sizes of calipers using them in different
combinations front/rear and with different rear pressure regulators,
different pads, etc. on a 93 968. The car is a daily driver and has been
tracked heavily at tracks around the country. I also race a 125 shifter
kart. I started researching braking systems recently when after speaking
with a number of so-called experts in brake systems including Brembo, Alcon,
CoolTech, and others, I was unable to get reasonable, thought out answers to
what I felt were basic questions. My conclusion is most of the folks out
there, including Brembo, Alcon, CoolTech, etc. do not design these upgrades
as a total system solution. (I know I will get flames on that!) There is
much more to this than bolting on larger calipers and rotors. I haven't
addressed here the additional issues of master cylinder size and booster
size which not only are critical components in regards to pedal feel and
stopping power but have numerous variable related to each of them also.

They are 90mm Hella headlamps. I run 2 high beams per side for night racing but it could be setup for hi/low beams.
They are from here:

I want to cut those out and replace them with with bixenons, but I'll need to find ones that are the same diameter...

I can definitely wait, I have a whole lot of projects in the early planning stages, just slowly doing research before I'm ready to start sourcing parts and then start hacking things up...

the way i figure, better to go to the 997 lamps and instead of just hacking up the fenders you get the CF trim from GT Racing and hack away at those pieces instead.
that way you're installing everything after a mock-up has been completed. and your HD install ready to go... i think the hood stays stock. i believe the 997 lights can be installed slightly lower in the fender to enable a minimal build up of plastic on the fenders behind the top of the lamps.
then there's the matter of the 997 air dam and splitter down low...
my car should be screwed royal before i'm done.

Here is the 2010 version. A single PIAA 600 HID per side.
The lights are just attached to a piece of flat stock aluminum which inturn is attached to the fender and the inner fender support. Cut a piece of ABS plastic to fill the hole in front of the lights and paint everything else black. The cover is just lexan cut to the shape of the hole and attached to plastic tabs which are screwed into the sides of the headlight opening.

+1 on not really needing rear brakes - but aesthetics as long as safe and functional are a goal. Planning on 350m front, 330mm rear rotors with full parking brake functionality.
I saw an Acura with fixed "ACURA" caliper front, sliding rear caliper rear today. The mismatch really stood out.
