Bigger isnt always better man. I would go with the GT. If I am correct going to big can create a really big understeer problem This is created with the sizle of your front sway bar being a lot smaller. Every guy I have talked to go with the GT rear sway bar. I just bought one today off ebay.
Ahh, so you're the one who got the GT sway bar, I was watchin' it. congrats on it, but eventually I'm hoping to have the power to correct that understeering so I am going ahead and getting the Cobra sway bar.
