I�ve used these in the past on other vehicles and love the adjustability.

I bit the bullet and went Ohlins, but replacing all the bushings and arms was key.

Suggestion
It was getting a bit harsh and probably could have benefited from fresh shocks, but I'm replacing with Feal 441 coilovers.

I will definitely look into the replacing the worn bushings and going from there.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Looking to see comparison photos of H&R lowering springs vs ROW M030 on a C4S.
also what is everyone�s recommended shock/strut? Bilstein B6, B8 or Koni Special Active?
This is what H&R springs on Bilstein "yellows" (not sure the model number) looks like. I am replacing this setup after about 60,000 miles. It was getting a bit harsh and probably could have benefited from fresh shocks, but I'm replacing with Feal 441 coilovers.
I can't comment on the choices you suggest but wanted to suggest that you refresh all the bushings and arms etc... I recently did a full overhaul on C4S with 85k on it and wow what a difference. I bit the bullet and went Ohlins, but replacing all the bushings and arms was key.
I can�t justify needing $4k+ coil overs which is why I just suggested the above. I don�t do anything but cruise to work once a week, some date nights with the wife and some spirited driving here and there.
I will definitely look into the replacing the worn bushings and going from there.
After talking with Gert, I have decided to go with RoW M030 springs and Koni sport shocks. I�ve used these in the past on other vehicles and love the adjustability.
spring choice was because I didn�t want 1� drop all around. A 20mm front and 10mm is perfect for my taste.
Shock wise I wanted dampening adjustability which the bilstein doesn�t offer. You get what you get with bilstein.
Gert hooked me up too, with RoW M030 and Koni yellows. I'm very pleased. I also replaced every suspension part containing rubber, plus the strut top items etc. Here's the look you'll be getting.
I too am in a pickle with which setup to go with on our C4S. @ 92k miles the stock stuff is way done.
I have a .1 C4 with the B8's and H&R's. It is a decent ride but a week ago I did Ohlins R&T on a customer's .1 C2.... I wish the Ohlins were not $4k for the C4's otherwise I would have them already. Set at 15/20 they're pretty awesome for street use and the odd thing is - despite lowering the car to M030 spec the car is much quieter.
Would be curious to see how the M030 and Koni setup rides.
I also have a aeorkit .1 C4 that came with the Feal setup- I will be curious to see how these ride when I finish the motor for that car.
