based on warranty alone, I went with BC.. mines a gen5 but they for sure make them for your car.
I went through Josh @ Import Image Racing... $999 shipped for BR series coils with custom spring rates.. 10k front/8k rear... None of the others offer this stiff of a spring rate, but BC had no problem with making it happen... alot of people that I spoke to said they would be too stiff for daily---they were wrong.. I've put about 2k miles on them around the DC beltway without a single complaint... We'll see in 10k how they are, but they've been worth every penny so far..
