Watched Luke's video....
So, let's set the record straight on a few things.... first and foremost, he/Luke has worked hard on his driving and race program to the point he can make a living doing it which means he's a great racer! But this has absolutely nothing to do with what we are talking about here! And this guy would win driving anything! So hanging your hat on this fact is just plain silly with respect to this tread. There are many other folks who can tune a race far better than Luke and other great drivers who just can't drive! The two are not tied together.
Next, Racerdude, you need to retake chassis 101, then go back a watch the video again! The pinion angle he is talking about is totally different than what everyone else is here so it's apples and oranges. He is just referencing the pinion angle vs a horizontal line and or flat ground which he calls ZERO DEGREES. The driveshaft angle has no bearing with his reference to PA! Therefore the numbers he references have no bearing to other combo's with respect to how the rest of the world measures PA! And BTW, come on now, why in the hell would those two builders tell you swat even if you asked, and who says they would even be right! Why don't you call them and let us know how that goes just for kicks.
If your so dead set on following what Luke or anyone else is doing/saying, go try it yourself rather than waste time BS'ing here not to mention stating for others to go try it and report back to you! And a word of advice, just because something works on one combo doesn't mean it would for everyone else's. If you really want to flog this deal, get a data logger with a shock travel sensor and have at it.Then report back to us!
That is why Luke is someone who American trusts to setup and tune their cars at the track. Call American and ask them if they have Luke set up their chassis
Next in the chassis 101, luke is using a different driveshaft so that he can run pinion angles that would put normal driveshafts in a bind to the point of breaking per the article I linked earlier
Next, I have called them. Which is literally why I am telling others to call them who are calling BS on this thread. So please, why don't you do something I already have.
Next, You said I should go do this myself and set up my car this way. I have done that and as stated earlier in this thread I have seen improvement from it. Have you tried it? Have you experimented with it? No? It is easy to say there is no difference on something you have not tried. This is why in this thread I said to go try it and then report back.
yes, you are right that something that works for one combo may not work for others
The thread was originally in regards to what the pinion angle should be on the car. My answer is around -1 degree to start
My further advice is that a pinion angle adjustment can and will make a difference in overall consistency in a car in a game that is often won by thousandths of a second
