What website or place did you purchase them from? Are they generally about $450 for the pair?

 

I wonder how the Belltech sway bars compare to the Hellwigs ??

I had a coupon code that saved me like 15% I think. I always google the part number and see what turns up. They just happened to have the best prices on the sway bars. As far as which one is stiffer, I used this guy's tech pages when I had my Lightning. Fantastic reading material...
