Does the rear bodywork of, say, a McLaren M8 or McKee have to remain intact (D3 Retro Can-Am)? Or can I cut it off to facilitate exiting the air out from under the body?

How about the same question for Jail Door bodies?

I leave 1/2" from the top. I try to follow rules, but i'm finding differences at places I race.

I understand you're looking for D3, but I don't run that yet anyway. I'm sure those fellas will chime in.

Tex,

In Jail Door bodies most guys do not cut the rear off. I have run a Lotus 40 with it on and the guys running the Lola T70 have done the same thing.

As for D3 and Can-Am, etc., they cut the rear of the body the same as IRRA™. Most leave around 3/8 inch back there so there is enough "meat" to attach the spoiler.

The only thing bad about Retro is admitting that you remember doing it originally.

And, there are no rules that forbid it. Generally in D3, we cut the back so as to leave just enough to mount the spoiler material.
For the McKee, one could punch all the vent holes and obtain the same results, that might gain you Concours points!

In real life in the 1969 Can-Am, at least two cars, the Ti22 and the Lola T165, had their rear body work abbreviated in the same manner as what is being done in D3 and IRRA™ racing today. :)

Thanks for the replies. I "assumed"(and we all know what we get when we "assume") that the bodywork could not be shortened. Now that I know different, I see some M8's in my future!
