around how many db's does it take before you have to start reinforcing the car and windows and door panels and stuff? and what exactely do you have to do?
im not hijacking your thread lol..sorry though its just a similar question...but i saw some vids of comps and stuff and people were hitting like 159 and 160 and they like were having to hold the door in place and like every wall of the van was flexing...and how come on some that hit that hard you dont ahve to?
Depends on the car sometimes. A lot of major competators do reinforce their cars though. I've seen some put stuff in their doors, (even concrete) they put extra layers of metal over the doors, they get super heavy plexiglass or something similar and put that in place of anything glass, (they usually bolt it on). Sometimes they just put patches over the edges of the door and bolt everything shut, so the only door is the driver's.
