Practical ways to measure lift, downforce and drag on a 997 GT3 (?)
I've just posted a thread with a very similar title in the performance modifications forum, here:
https://rennlist.com/forums/performan...l#post13898932
(I wasn't sure where to post this, but then I realized that this will equally interest/disinterest owners of virtually any other 2 door Porsche, and maybe even some 4 door Porsche owners as well. And it seemed silly to have one discussion in the 997 forum, another in the 997 GT2/3 forum, etc.
On the other hand, the performance mod forum doesn't get a lot of traffic. Solution? Threads like this in a few forums to let anyone interested know to go to the performance mod forum.
Hope this is helpful!)

I race Formula Atlantics and we use an AIM data acquisition system with them with shock potentiometers on all four corners olongapo other things. By incorporating the spring weights and rocker arm ratios we can arrive at a reasonably accurate measurement of downforce. An AIM system is phenomenal and not very expensive if you are seeking these kinds of answers.
