window cutout question

[briguy]

Hello,
Should I cut out the back window, and rear door windows on my Audi
dtm body for proper airflow? I have seen a lot of vids of guys not cutting out any windows. Thanks

I would cut the side and rears mate they like cool air and heat does build up with these cars and the performance will drop off without them getting some air flow

 

[briguy]

will do, and thank you..

My shell had the sides and the back cut but no windshield.

I hate cutting out windows, but I don't race and don't hammer for more than 20 minutes at a time.

Ruins the looks, weakens the shell, just looks wrong, unless ... you can make it look like it was 'meant to be there'. By that I mean I cut some windows like they've been lowered, on a 1:1. AGREED, before you say it, I'm contradicting myself as it is weaker than the ovalled manner in which Voo did his, but it looks MUCH better.

To me, LOOKS are VERY IMPORTANT.

Sorry, that's me!!

agreed al it does weaken the shell but they need cool air and you can cut them to look open as you said which I like not a fan of the oval cutting just don't look right fg doe's make a roll cage so if the worst happens and it go's on to its roof it should help

you should not cut out the back window it messes up the air flow to the wing & you loose down force. this is what frank killam told me at a race.

Probably very correct.
The airflow will be erratic and with extreme temperature, thus air density changes depending on direction.
If the wing does normally have an effect, then it will definitely be variable I can imagine - just like 'real racing' (I mean 1:1)!!
