Hi has anyone cut holes in their rear bumper to reduce drag. If so any pics I'm looking for ideas ?
 
I know of quite a few who have drilled holes in thier rear bumper. Mainly people who visit Santa Pod often. It does make a difference too.

Watch out driving at speed in rain though as the car behind will be blind in your spray.
 
Yeah it's a track/ sprint race car I want all the gains I can get haha.
oh right something to bear in mind
 
I looked on google images for inspiration and mocked a few up in MS paint.

The theory behind it is sound if you can live with the cosmetics
 
iv seen boys putting the holes quite low, i would think more in the middle would have good effect. or just cut the bottom half off, time attack style
 
Excuse the horrendous understeer in this pic!
