Anyone know of a strain gage that measures in lbs or kg's that I can use to measure the downforce of my new rear spoiler. I plan on mounting it underneath the truck lid between the lid and the fiberglass frame. Like where the arrows are pointing:
I figure if I can find something that reads the downward force I can just set it up with a video camera pointing at the gage, drive down the freeway. with the car on the trailer and get some readings. |

I agree with the 30mph statement ...and its probable true at even higher speeds! say around 60+ mph. Ground effects just are not what people think they are or do .you need a pretty good amount of speed to over come the amount of drag they actualy create...to go from drag and slowing the car, to down force helping the car hold the road ...maybe that university professor will chim in again with he`s fancey charts? he showed it once before and i cant find it ..This is all just my opinion ,kinda like thinking out loud ...good luck with everything i really do hope it works for you

Mike You've never seen Joe Chen's A Mod car run, eh? On a dirty section at Packwood, I saw him throw up a rooster tail 25 feet in the air from his difusers....maybe @ 60-70 mph. The thing is killer.
