Rear Roof Support (Hole or no Hole)

[tsnmotorsports]

On your Rear Roof Supports would you cut a hole in either side. I have heard to cut a hole in the passenger side to let the air flow through to the left rear roof support and onto the spoiler when the car is in the middle of the corner.

What are you opinions?

Thanks for your responses!!

The proper name is a C-pillar and to answer your question yes the right side pillar does block air from getting on the spoiler atleast the right side when the car is yawed. If rules allow, run as big of a C-pillar you can on the left side with window not cut out and cut the window out of the right side. Most rules require either both have windows cut out or both have solid windows. If there are no rules and you want the best of both worlds run a solid left side pillar and make a couple of 2" straps in place of a C-pillar. (That's how we did it in the early 90's until the sanctioning bodies caught on to it and made changes the rules)
