What testing would you do other than install them, get it on track, and try it? With an unbiased driver/drivers who are willing to give an unbiased opinion.
I've installed these and I'm paraplegic and I could/can feel a huge difference in the car immediately. My wife who does not drive on track also felt a huge difference the very first time she got in the car and drove it on the street, as it made the car much stiffer. I also stated one of my instructor friends at BIR stated similar as well when he drove it, and he has driven many mustangs.
Yes these cars may be stiff enough, but they will get stiffer with these and it will make a difference on track, I'll stick to my opinion to my dying day on that one. Everyone else on here who has installed them say they work as well, but you guys who have never even tried em keep saying these do nothing, and for Terry to say we all have confirmation bias is quite insulting. Aren't we all in this for the same thing, to make our cars faster?
Terry Fair also stated there is no data to prove these do anything, yet nobody has shown us any data they don't either, just your opinions, same as us who have tried them and expressed our opinions, big difference here is we don't insult you guys about it, until we get the snyde comments.
Don' t get me wrong here, I completely respect your/Vorshlag opinion as you guys have been doing this much longer than myself, but what I don't understand is you and others who have not tried them being so negative and spiteful in some of your comments about them.
As someone on facebook said, "it does not matter what others think, if it boosts your confidence and makes you faster on track, that is all that really matters". At this point I'm very good with that statement and I appreciate your time on this.
