Never seen this before in all the years

It is cool. I downloaded a copy years ago because i figured it might not be hosted forever.

On a related note, apparently the UK and Europe spot lights only exist to homologate the holes as brake cooling. Anyone know any similar details?

Whoa nice find!

And holy Canuckr sighting!!!

I have seen some of this stuff, but not all . Could someone please explain? They needed this to compete in the certified series is that correct? I remember something about the Euro cars allowing brake ducts with the European fog light set up. I was checking out the link and didn’t see anything about it . I started seeing aftermarket brakes and gave up.

Excellent question! The history here I've learned is not well documented. Much of the credit goes to Rboosted717's extensive research into this subject. You can read more about this two cars here and here or see his Racing Picture Thread here.

Yes, Honda sent production ready cars, several bodies in white chassis, and parts, to the UK for FIA certification. This certification/homologation was required for this chassis to endurance race. I've learned the European race teams quite simply, do not receive the credit deserved for developing what became the USDM and later JDM model DC2 ITR's. Due to the demands of European endurance racing, the following production changes were made:
-Projector headlights (all lights required to be functional)
-Larger hubs (re: five lug) to better handle 24hr Endurace racing stress & temperatures
-EDM/UKDM front fog lights for use as brake ducts, per regulation limitations

Further developments from racing teams like Foss-Tech:
-Re-enforced rear lower control & rear trailing arms due to heat from 24hr racing. These have now been copied by Honed Motorsports and available today.
-Suspension design improvements, which later influenced US race teams like Realtime Racing, others.
-Carbon Fiber glory: Dashboards, door panels, rear interior panels, fuel cell covers, and more, due to race regulations, as well as intake designs, brake ducts, etc.

Carbon Fiber goodness:

More: Race purpose bodies were supplied to various race teams across Europe (Germany, Belgium, UK, etc.) Semi-complete bodies are believed to have been sent as "production ready models" for use in Group N.
