Coilovers
Looking to get some coilovers for my f80.
Don’t know much about coilovers so hopefully someone can point me in the right direction. -best coilovers for my buck? -recommend buying them used? -best overall feel? -best on the market? -difference between the adjustable springs? Hopefully I’m asking the proper questions |

There's not a, "best" coilover but only a best for your needs. You need to provide details on what you mainly use the car for (street/track) because that's going to dictate a lot of the categories you listed above as well as if maintaining EDC is important or not.

Popular option is Ohlins R&T but I don't think they go slammed ride height if that's what you're looking for. KW V3s are popular also.

This but you will probably end up needing to buy a spacer for the rears. I have them and no complaints.

You’d do V3s over R&Ts? Only reason to go with the V3s is if you want to slam the car. I first installed V3s on my ‘03 e46 M3 in 2003 and it was the worst damper I’ve ever used. I could not eliminate the rear from pitching regardless of C and R settings. I could only take it for a few weeks before pulling the V3s off of the car. I’d hope they’ve addressed this over the next 2-3 generations of the M3/4 but I’ll never use any product from KW.

Out of the box Ohlins R&T operate in an odd segment in the market in my mind. Can be too stiff for the street yet is outclassed in heavy track usage and has relatively short rebuild intervals for a street biased shock. You pretty much need to go with a re-valved and re-springed version from a shop like 3DM to dial that setup in - at that point I’d say it’s a pretty fantastic option for a mixed duty car. Even turner has jumped on the wagon and revalved R&T in the opposite direction to make them more compliant for street use. But idk anyone who has run those yet. Edit: sorry I mis-tagged RElias21

3DM and PSI both offer R&T street options with lower spring rates and appropriate revalving. I have a set of R&Ts on my R56 Mini CS with spring rates are 25% lower spring rates and it’s been a wonderful street setup for 13 years. For basically the same $, I’d go Ohlins R&T over KW V3. I don’t know how many people know this but KW stole another competitor’s patented valving for the V3. |

Agree. ~450 lbf/in F and ~700 lbf/in R spring rates are a great street setup. Properly valved Ohlins R&T dampers for the rates above will result in a compliant ride yet sprung high enough to get improved handling performance. Then with only 6-8 clicks of the damper you can go between a more compliant biased ride to a more performance biased ride. As a compromise, you could find the middle ground between compliant & performance to come up with a single F and R # of clicks that you set and forget. With my R56 Mini CS, I’d adjust the R&T damper settings 6-7 turns more open for winter and the car is nice and compliant for winter driving.
On my wife’s M240ix, I installed a MCS 2WR with F/R 500/800 lbf/in and it’s a great street setup. She wants all of our cars that don’t already have MCS setups to be upgraded with MCS setups. She’s spoiled |

I run the Öhlins kit on my M4. I laborated a bit with springrates. The kit came with 230 N/mm rear springs and 90N/mm front springs. This was way too stiff for me and the rear dampers were also wrong with too long shock bodies, which Öhlins fixed fast. After my complains they sent me 190 rear springs instead and shortened dampers which improved the car a lot. These spring rates are now standard in the kits ansd also the dampers. After this i changed to 160/80 springs which i run now and it works fine. Stock valving works fine with these springs which is also seen when you look at the damper dyno curves and compare the stock dampers with the Öhlins.

Yes, you can run them with the original valving but you’ll be limited on the number of turns/clicks you’ll be able to use. They’re valved the rear to handle a 230 N/mm spring and even with that spring rate you can overdamp that spring so revalving for the softer springs allows you to run from a lot closer to 1 (if it goes from 0 to 19 clicks) and to 18 because Ohlins doesn’t want you to use 0 (fully closed) and 19 (fully open). So with soft springs you’ll be limited to maybe 10 useful clicks, possibly fewer than that. If you change your rates by more than ~+/- 35 N/mm, you should revalve to have a nice useable range from at least clicks 3-16 from fully open. I ran rates that were 25% softer and I could only use around a max of 11-12 clicks, realistically useable range is 9-10 clicks (click 3 to click 11 from fully opened). If I’m buying a damper with 20 adjustable clicks, I want at least 14-15 to be truly useable clicks. |

I’m seriously considering Ohlins x Turner Street Coilovers. I daily my M4 in NY. Never tracked it but I’m open-minded to it in the future.
I’m guessing I’d need to buy a separate EDC delete kit for the ohlins coilovers, right?
