That is the setup I wish I had went with. I asked for 12/8 with my BCRs; and though it's very DD-friendly, I drive spirited and wish I had the added stiffness at times. On minor bumpy roads it'll definitely translate through to the cabin/passengers. But rougher surfaces, it'll suck-up those bumps and it'll feel better. Playing with the dampening will adjust how close to "stock" your suspension will feel too. I just changed from my winter dampening setup to the summer setup; up from 15 up front and 12 in the rear to 18 up front and 15 in the rear. I might adjust the rears down though cuz even at 90+ degrees out, I still break the tires loose easier with the increase in dampening.

I've got the 12/10 setup on my 350 with 5 out from full stiff on front and 7 out on back....feels great. No complaints what so ever and she's a bit tucked in back with no gap up front...gonna try maybe a touch softer just to see how it feels.

Thanks for all the information. I think I am going with the 12/10 setup. The 14/10 maybe too stiff of a ride.

I have the 14/10 setup and quite enjoy it!

I have the AWD so it weighs about 250lbs more up front. The higher spring rate implies less shock travel, so I went with 14 up front to avoid bouncing around as such. I'm set at 18 clicks hard up front, 12 clicks hard in the rear, but I will likely stiffen it up more!

I live in Alberta, Canada, and our roads suck, but I can assure you, this is not "stiff"! Passengers who have only been in my car a few times before these coils can barely tell the difference... only I can as it happens to be my daily driver, and the difference is not that noticeable. The car just feels a bit firmer and a bit more responsive.

I have 12/10 and love it. On the street, I use mid to soft setting and it rides like stock. On autocross, I use stiff setting, and it handles like a champ.

14/10 should be fine. I ran 12/10 on a lighter car and I wished I went 14/12.

I ordered BCs 20/18k w/swift springs upgrade. Should be here in a week or so.
