BC Racing vs KW Coilovers
Anyone running these on their 07+ sedans? What are you thoughts?
I'm leaning toward the KW v2.
My first choice was JIC VIP but apperently they're not out for our cars yet and i can't get an answer from them as to when they will be available.
P.S. My stock shocks/sturts are suffering with my eibach springs. There are no aftermarket shocks/sturts available for our cars so that's why I'm going for coilovers.

Why aren't you considering the JIC FLT-TAR line? If you're considering the KW V3 (I don't believe V2 is an option, or at least I haven't seen anyone with them yet), you should consider the FLT-TAR also.
With BC, you're limited to the BR series.
The spring rate is 12/8, with similar features to the JIC.
Construction, as far as features, seems about the same.
Independent height adjustment
More dampening range (30 vs 15 for JIC, 14 for KW).
Spring appears to be linear.
BC used to have a problem with rattling, but I haven't read of any complaints about them for a while. If they solved that, then the BC is a good option considering the price/features.
I could not find the KW spring rates on their website. Keep in mind that they appear to be progressive in construction (I've seen pictures of both progressive and linear springs, so I don't know which is exactly available for our cars) versus linear (BC and JIC). I prefer linear to progressive personally.
The KW does offer compression adjustment, which the BC and JIC do not.
KW does not offer independent height adjustment, hence the use of helper springs (I personally dislike).
KW will be the most expensive.
Unknown if re-buildable in the states or not (JIC is done in Cali, BC unknown).

Why not the Tein SS-P's? This is likely what I am going to go with. They run a 9kg/8kg spring rate which should have a pretty good ride. In terms of price they will fall between the KW/JIC and BC ($1500-1600). They have 16 levels of damening adjustments, and are EDFC compatible.
There are also K-Sport coilovers that are 9kg/7kg with 32 levels of dampening, that are about the same price as the BC (under $1000).
Tanabe has their Pro S-OC coilovers that are around 10kg/9kg. They do not have dampening adjustment, and you have to re-use the factory top mounts, but all feedback has been pretty good on them. These are also about the same price as the BC/K-Sports of the world....
From what I can tell, all of the above are linear springs. All but the Tanabe's have independant height adjustment (without helper springs).

JIC is good stuff, and the VIP's sound like they should be good for the non-track people.... It really depends on what a good price is. It they will do the install (which is super easy) and alignment, I think anything under $2400 is pretty good for those.
