Default Bcr coilovers 16/12 or 14/10

I have a 2011 ISF getting ready to put AG wheels f421 spec 2 9.5x20 +40 and 10.5 x20 +45 and lower it on some BC coilovers with swift springs I have researched tons of threads on this subject and was leaning towards the 16/12 but the shop I was going thru was telling me that might be too stiff and I just wanted to get somefeedback anyone currently riding on that spring rate?

ive had both bc coilovers with the the swift spring upgrades with both spring rates you are looking at. the 16k/12k feels a lot more stiff even on soft settings. the 14/10k is wayyy more comfortable.. its almost crazy how smooth it can be at how low i was at the time. now with the new 16/12k set up at the exact same ride heights, i feel like im jumping all over the place on every little bump.

Woow thanks for the info I just head so many people going with the 16/12 I figured it would be good
You think I ll be alright on 20x9.5 2010.5 +40 +45 lowered on the bc's? Far as fitment wise?

Springs are not inherently stiff. Shocks make strong springs stiff.

It all depends on what you want to do. If you plan to track your car, you need all the spring you can get. If you just cruise with it, then get the ride you want, which is more than likely the softer springs.

I have BC with 18k / 14k swift springs. I have 9 / 12 clicks using Figs recommended tracking. I think it rides but I ran 16k all around on my STI so I might just be used to it.

I have 16/12 and 8 and 12 clicks and IMO rides pretty soft. Having said that, my 997.2 on sport mode rides a LOT harder so perhaps "soft" is relative.

I just replaced my BC 16/12 swift upgrade with a set of KW V3s. Night and day difference. Save up and go for the KWs.

With what spring rates? Telling the guy to buy KW's without saying what spring rates is pointless.

Its whatever that KW sets. However, my F has never been on a track and never will. It just puts a smile on my face everyday.

Is there a reason you don't just want lowering springs like swift or eibach?

I've got BCs with Swift in 16/12 and they're great. Plenty of dampening adjustability for comfort and I don't bottom out on every pebble in the road especially for how low I am. I don't track my car, its simply my very fast, very f-ing awesome daily driver!
These rates work for me. Good luck.

i have BC 16/12 and i wish i would have either gone new OEM shocks or much higher end coilovers. they feel cheap, even from new.
