buddy club sport N+, megan street series, bc BR series, tein flex z and d2 RS series. all these coilover are in my price range 800-1000. my car is a daily driver and comfort is my #1 priority which coilover would give me the smoothest ride? if any body has any other suggestions please comment
Off of that list you posted only the Tein and BC will give you a decent ride quality.
I can't speak for the K tuned street series but the reviews seem good.
I have Fortune Auto 500 series and absolutely love them. I had Buddy Club N+ on my RSX and loved them as well but they are VERY stiff.
Put some miles on the Tein's this weekend, wanted to share.
For 12F 7R springs it rides super smooth. Honestly wish it was a little stiffer out back. But for those spring rates it's comfortable. I've got the comp/rebound set to almost full stiff and it soaks up Chicago bumps really well. RIP to my poor fender liners tho but here's how I'm sitting. At this height the upper A-arms will and have hit the shock towers.
