curious as to what control arms are you using. I've been in contact with SPL parts for product development and test fitting since im local to them in Austin. They said they will get with me when they need a test fitter, they are working on other projects it seems.

The stiffer front sway can increase grip if your are running very sticky tires, aka Hoosier's. The front sway will keep the car from rolling further, which can improve the front tire's camber. It can also help with putting down power at the rear by reducing roll and changing the stiffness ration of the car.

SCCA Nationals update pending, getting my videos uploaded, stay tuned.
