Which coilovers?

What is the best overall dual purpose coilovers with the least amount of headaches like install issues or noise?
Modest drop with good damping and better than stock. 1 or 2 track days per yr
jrz and ohlins rt have good reviews
For ohlins which springs?

What’s your budget? Are you looking for single or double adjustable dampers?

From what I’ve read, it sounds like the latest JRZ RSone and RStwo dampers have a chronic noise. I have not heard it in person so I can’t comment on the potential cause(s). If want noise free then JRZ isn’t an option (except for the Pro2 and Pro3.

The Ohlins R&T is a good setup for a car used primarily on the street and used only ~5 days per year. You definitely do not want the original spring rates Ohlins offered for the F8x. For a primarily street driven car, I’d recommend F 400 lbf/in and R 700 lbf/in spring rates. There is a company that’s revalved R&T dampers and now offer R&T “track” kits setup for the track.

Budget...There are other options available for the F8x that are more costly yet have better track performance without sacrificing daily driving comfort.

Ohlins

I'm not a big fan of the Ohlins on this car. The shock bodies are too long and will not allow it to be lowered much. Couple that with very high spring rates (Rates I believe were chosen to try and keep them off the bumpstops because the bodies are too long). Also these have nothing in common with the TTX race shocks, other than the color. I just feel these were not a well thought out kit, and the parts were taken off the shelf from other cars without any major re-design. One other item of note, it's very nice to have the spring above the tire so you can run as wide a tire as possible on the front of this car. These are ~8" long springs and will sit behind the tire, which is not ideal.

For a mostly street I'd choose TC Kline. These are twin-tube single adjustable and are basically Koni shocks. You can pick your spring rates with this kit and they are relatively soft and very streetable. They ride super well, and come with camber plates. The springs also tuck above the tire.

For more track orientated I'd go MCS singles. MCS you pick your own spring rates, are a true monotube design, and you can change nitrogen pressure as well. Also a small thing, but the agusters are much easier to set than Ohlins. These are rebuildable in the US, and are heavily based on Moton / JRZ. The founder of MCS is also the founder of JRZ and Moton. You also can tuck the the spring above the front tire on these as well.

FYI - I have owned Ohlins, JRZ doubles and the MCS (full double - remote) on this car.

On my E92 I've owned TC Kline and Ohlins. (Ohlins were great on this car btw)

That would be a big mistake from Ohlins. I can't believe they rushed the design considering the big experience they have.
Yes they don't give a big drop, but function over image is not a bad thing...

How do sach zf compare to mcs single adjustable?

They’re not close in price and performance. The MCS 1WNR dampers only cost about the same as the Sachs complete suspension kit (or more - Turner has the Sachs F8x kit on sale for ~$2330). With MCS dampers, you also need to purchase front (camber plates) and rear (clevis) upper mounts, main and helper springs, spring couplers, rear spring height adjustable mount, adjustable end links, etc. I’m using MCS 1WNR (e92 M3), 2WNR (F82, no longer using) and 2WR (F82) dampers. I’ve also used Moton (e46 M3), Ohlins (e46 M3 and r56 MCS), JRZ (e92 M3) and TCK (e46 and e92 M3s, S2000) setups. I prefer and highly recommend MCS setups over other setups based on my own experience. As for the street, I haven’t found another damper that performs even close to MCS on the street (i.e., compliant) as well as excel on the track like MCS. I have close to 30 years of track and suspension setup experience.

FYI, MCS dampers were designed from a clean sheet and not based on existing Moton and/or JRZ dampers. The rights to Moton was sold to AST so MCS would be in legal trouble if they copied any part of existing Moton designs.

Agreed that no parts interchange with JRZ or Moton, but it's the same designer. It's impossible to unlearn what you've learned and experienced when designing Moton and JRZ. What I was getting at is these are basically the third generation of those two designs so to speak.

I love my MCS. If they disappeared tomorrow from my car I'd replace them with the same thing, which for me says something.

If I were only tracking 1-2 times a year though, TC Kline would probably be my choice. I'd be giving up a few seconds on the track but street manners would be better. Twin tubes without the high pressure of monotubes will always ride better / and have performance trade offs as well.

KW is basically a Koni btw (Koni design made for KW last I knew). Still twin tube and not ideal for a performance shock and generally not rebuildable or revalvable.

Agree. Öhlins would never just throw together a suspension kit. And like you say, they build there suspension for functionality, not for lowriders. Too low and you upset everything with wrong suspension arm angles, less camber on compression and more.
I wonder how many who complains about suspensions actually knows how to set there stuff up properly.

however, there is a thread on the M2 forum repording strange noises from the R&T and Ohlins not willing to sort it out...Was about to purchase , taking adantage of black Friday, but such reports are putting me off.
Has anyone heard of http://www.ycwsuspension.com/
Been in touch with them they are really helpful, hand build, 100% dyno tested etc etc.
Or I will go for Intrax or AST...

What is the final cost of the mcs 1wnr with all the extra parts?
Is it night and day compared to something like ohlins?

MCS singles are about $3350 list with everything needed (springs, shock mounts, etc...), so a small bit more, but you're getting a lot more as well.

I'd stay away from YCW just from the standpoint nobody has used them, so there is a lot of risk, and even if they are good, resale would be pretty much $0

A few months ago I uninstalled the Ohlins from my car and it is the best choice I have made. The customer service is also bad.

Thinking about installing Bilstein B16 or Clubsport ...

Hi,

it always depends on your budget and what you want to achieve.

If you don't want to spend a decent amount of money take the entry-level kits as the Ohlins or KW have in stock. V3 or R/T. If these kits are already beyond your budget buy you a set of springs.

To be honest I used in the last 25 years always brands from companies who are also the OEM supplier and motorsports suppliers of BMW M. So there is only ZF Sachs, Bilstein, Ohlins and KW to choose for BMW cars to be on the save side.

If you visiting racetracks with your daily 4 - 20 times the year take a 3-way adjustable kit. Or take the real OEM and homologated racing parts if you don't ride on public roads anymore ;-)

The MCS 1WNR dampers ~$2650+$500 camber plates+$140 strut adapter+$300 rear mount (coilover or non-coilover)+...is >$3350

Around $4200 but it will depend on whether you run a coilover setup and n the rear which requires an upper clevis mount, which camber plated you go with, which rear spring adjustable mount if non-coilover rear, Torrington bearings or thrust sheets, spring rate and length, depending on spring length will determine if you need helper springs and couplers, decide to use tender springs,...

2650 - Shocks
140 - strut adaptor
280 - rear mount
280 - springs
=3350

I didn't count camber plates as Ohlins either didn't have them or would need them too. Trying to make an apples to apples comparison, but indeed camber plates are needed if you are going to track the car.

Really not that terrible on pricing for the mcs. Im trying to decide myself between the TC Klines and the MCS 1WNR. With about a dozen track days a year and regular street use.

Ohlins? I replied to your $3350 for a compete MCS 1WNR setup that you can install on your car. I don’t care about what Ohlins does/doesn’t come with - you cannot install an MCS suspension (well, not exactly true if you have a custom set made with no height adjustment) for road and/or track use without camber plates at a price close to $3350 . BTW, I’d strongly recommend adding the digressive valving option.

In your price above you left out spring couplers, helper springs, thrust sheets...
