So, I have narrowed my search to the following. Suspension experts let me know your thoughts...

Koni's + BMW Performance Springs

-OR-

BMW Performance Suspension

Yes, still have run-craps and will switch to PSS' once they are done. I dont track and my objective is to lower the car a bit (from Sport suspension) and improve the ride and handling.

Thx

Which Koni's are you interested in?

A lot of people seem to like the FSD and Eibach Pro Kit for its good balance between comfort and performance, but I went with the Koni Yellows and H&R Sports. I like the predictable characteristics of the Yellows vs the FSD.

Thx...I was thinking the FSDs would be best since I dont track. Yeah, I'm leaning towards the BMW performance springs with the Koni's for the same reason.

Yellows would probably pair better with the new yellow performance springs. That said, if it were me I would get the system that was engineered to matted together - complete performance suspension.

The Yellows aren't bad at all. One benefit is that you can adjust the rebound so you can dial them in to your preference. The FSDs are not adjustable so you're stuck with how they come, but the people who have the FSDs seem to like them. If comfort is your main concern, you should be happy with the FSDs.

Full BMWPS with Koni sports (yellow) here. Perfect compromise between handling and ride comfort. I'd skip the FSD's; had those for 3 yrs; inconsistant damping.
If you decide go with aftermarket dampers instead of the whole PS kit, make sure you get the PS bumpstops with the PS springs. Dan@UnitedBMW will make sure you get the correct springs and bumpstops for your car.

Thanks for all your input...I'm still undecided , but leaning towards the BMW Performance suspension which could change to nothing after I get my (expected) bonus

What about adding stiffer anti roll bars front and rear? From what I've heard and read, this adds even more to balance and nicer overall handling when coupled with the springs and matching dampers.

Thx...believe me, I have thought about it. I spent $4000 (parts only) on my 135 suspension and am trying to keep my mod spend to a minimum for the 335

Any particular reason why you're looking into the Performance Suspension?

I'm leaning towards the BMW perf suspension to keep it in the family. I ran into a huge issue with my aftermarket suspension mods on my 135 with the dealer. Yes, we had a candid discussion regarding the Mag-Moss Act and the FTC 2011 report regarding Warranties. They still refused to replace warrantied BMW parts (also in writing) until BMWNA got on my side. In the end, they replaced the service supervisor but I dont know if I want to go through that again. It took awhile. I'm not 100% yet and would love Koni yellows (per everyone's recommendation) with Perf springs. Decision to make.

Understandable. What were you having replaced? If it was anything suspension related, I can understand them not wanting to fix the problem. If it wasn't suspension related, it should not have been a problem.

I had a frozen tie rod nut. Heating would not release the nut so I could not get an alignment. The dealer still had to prove the aftermarket parts caused this failure which they did not. BMWNA agreed.
