How bad is the standard suspension?

Is the standard suspension boring like the standard f30? I cant seem to find a sport line that I like. Would you wait for a sport model or just go with the non sport model with all of the other options?

IMO the standard suspension on the E9x is similar to the sport suspension on the F30's.

There's not a thing wrong with the E92 suspension. It's a great balance between performance and everyday drivability. I like it a lot.

Of course not, but I don't want it to drive like a Camry either.

Well, let's see....
  • Blubber for rear subframe bushings
  • Blubber for control arm bushings
  • Flexible steel arms vs stiff aluminum cast arms
  • Front camber fixed
  • Progressive springs
  • Pre-2011 shocks lend themselves to shocking pothole explosions
  • 'Spaghetti thin' rear sway


Kinda sucks, actually. M3 grossly improves all above for a much more competent handler. You can too....with a few part replacements. Also, not a suspension item but a large improvement in handling & ride: Limited Slip Differential.

There.

IMHO, I would never buy a BMW with standard suspension. You might as well buy a Camry. It's cheaper and more reliable.

I've read the thread you made for the work you did on your 335i very nice!

What would I need to change to make the standard suspension match the sport suspension and how much would it cost?

Shocks, springs; sways. The last I'm not sure of 100%.

But, shucks, score BMW performance springs + Koni FSD's - you'll have one sweet ride. Won't handle like M3, but won't have many of the most objectionable behaviors of the regular & sport suspension. Koni's ~$1K - dunno about springs - let Google be your guide.

You're buying a used car right? Why worry about factory suspension, just buy Koni FSDs. They're the same stiffness/handling as my ZHP's stock shocks, but handle bumps much better. Springs are tougher, since the aftermarket ones mostly drop the car quite a bit lower than stock sport springs, and OEM cost a fortune.

See, this is what happens, you read something on an internet chat board thinking some anonymous person can out-engineer the engineers who designed the car, and now you're willing to spend heavily - just like that.

Never ceases to amaze me ....

NO ONE can tell you what you're going to like, just go and drive some different cars and pay for the one that puts a smile on your face.

You must be comparing the Camry to Furby's F30!
I have driven a Camry, including one to Canada and back and it has nothing in common with the standard suspension on my E90.

Time tested and true, good advice!

That's why I went with BMW [M3] control arms, rear bushings, sways; strut brace; shocks & springs from Ground Control, the well known suspension house actively involving in racing.

And why Koni's w/BMW springs came to mind.

Our D has a standard suspension. it is better than the vast majority of cars on the road. It is nothing like a Camry. It is not as good as the sport pkg on my other car. Who ever said the sport suspension on the f30 is like the non sport on the e9x is pretty close to the mark imho. N4S

+1 The standard E90 suspension is worlds apart from something like a Camry. I'm not even sure how some on here can compare the two. The ride/handling balance is near perfect IMO, there is very little body roll and it is very composed over uneven road and at high speeds.

I think OP should just test drive and experience the difference for himself. I have a Sport Pack equipped E90 and while I love it, it can get a bit harsh especially with the craptastic run flats.

N4S, I feel you should know, and before this goes much further, the shocking truth: Toyota has rebadged standard suspension F30's as the nextgen Camry.

The parts are available if you wanted to purchase them after the fact. I wouldn't let the firmness of the suspension deter you from buying the car that you want.

Prerequisite for BMW M3 REAR SWAY: LIMITED SLIP DIFFERENTIAL

Otherwise wheel hop will be a new reality.

Out engineering the engineers who designed the suspension on the E9x is about as much of an achievement as being a better musician than Kanye West.

Yes, this is a very good post Kunal

I have a 330i ZHP I was driving twice a week to NJ for a teaching gig. I garaged it in favor of a Mercedes E320 I was able to get a great deal on.

Why?

The ride was punishing ... I love my ZHP and will keep it a long time (only 48k miles), but heavy 18's over low profile tires are not conducive to any kind of NYC metro area commuting - even over non run-flats. The Merc makes this trip a breeze.

Owners should really consider the type of driving they'll be doing and where they live - if you live in the south where the roads are smooth and you think you must have a sports package, go for it, but I'd argue for the majority of drivers, the standard BMW setup likely provides just the right amount of comfort and feel - most drivers think their cars handle "better" with SP, but the truth is they're no where close to the handling limits of their cars with either SP or the standard setup - nor should they be.

In fact, most people can't even drive a Nissan Cube near its limits. Many SP's are about marketing more than anything else.

We test drove cars with both the regular and sport suspension and preferred the sport suspension. The difference could be felt at normal speeds well below the limits of the car. The standard suspension car drove very well but did not feel as planted and connected to the road as the car with the sport suspension.

We opted for the sports suspension, ordered our 2007 335i Cabrio with sport suspension and had no issues with it in South Florida where the car was purchased. After we had the car shipped to our home in Manhattan we were totally unprepared for how unsuitable it was for New York City roads. The car was for all practical purposes undriveable in NYC. The ride was not only punishing, the car would break (bubbled tires, bent rims) when it hit a pot hole, construction plate, frost heave, etc. It was also not able to keep the tires in contact with the pavement on poor roads which made the car rather scary to drive hard as the rear wheels would bounce around and the rear end would start to step out. The situation was vastly improved by getting rid of the RFTs and replacing the OEM shocks with Koni FSDs.

Based on that experience if you are regularly driving in an area with bad roads I would recommend the standard suspension unless you are willing to change out the tires and the shocks on the sport suspension.

I got rid of my OEM 18" ZHP wheels when I bought it, in favor of 17" OZs, the ride is better, although I did it like you said, for potholes. Koni FSDs helped even more with the ride.

I actually just did a total refresh of my non-sport E90 330i suspension and tires within past year

Bilstein Touring Shocks (same as BMW factory shocks but Bilstein valving) w/ strut hats
Meyle HD front Control/Tension Arms
Meyle HD sway bar links
Michelin Primacy MXM4 ZP Run Flat

The ride and control is totally transformed. The first thing that went on were the shocks and tires. Boy, what a freaking difference. The Bilstein valving was so much better then BMW spec and new generation run flats are very good. Control arms and sway bar end links stiffened steering and added feel with no loss in comfort. I kept stock springs and kept the ride height (I chose non-sport on purpose). The car rides better then when the orig suspension was new. No pothole explosions, just solid thuds now over bumps. Its a great daily driver in the city flicking through the gears just like my old E46 now. Like seriously, if I was filmed driving this thing now, I would probably be seen smiling the entire time.

I drove the F30 non-sport as a loaner. Its really spongy compared to the my current setup. Im quite happy with the setup now and the replacement parts were quality and "cheap".
