The anti-roll bars may not be available yet in the U.S. Excellent anti-roll bars! The cup kit is very good also, albeit the ride is a bit harsh. I'm having #3 pads intalled on the front and #2 on the rear to make it softer... I have 16" rims, and the whole affair makes the suspension quite impressive.
I ordered the U.S. made adjustment bolts for the rear camber; Linh recently posted the contact information.
