Re: Vorshlag 2011 Mustang GT 5.0 - auto-x/track build
While the car is leaning a lot, take a look at the tires. It's obvious that the Watts is working. The rears are fully planted on the ground. Even the fronts look pretty darn good. See if you can get photos from the same angle / type of turn when you swap the rates.
One thing that I noticed (and many other people pointed out!) looking at pictures of our car vs the other top ESP drivers' cars if that our Mustang has a lot more LEAN, which also kind of crept up on us. The updates we made with the Whiteline bars, UCA and especially their Watts Link Kit added a lot of lateral stability and more grip, and the switch to Hoosiers from Kumho added grip, as did the concrete surface over our test site.
So yes, we are going to raise the spring rates from the current soft set-up (450F/175R) to a firmer set of rates (550F/225R). The soft set-up worked great for both road course and autocross events when we were dealing with other issues like lower grip tires (street tires all the way to the V710s), the steering shudder (yes, which is gone), and a clunky Panhard rod set-up. These rates are going on next week.
