[Eibach Pro Kit] Just click here & answer

My vehicle is a 2011 BMW 328i that is completely base - no ZSP no ZMM:

I am purchasing a brand new set of springs, Eibach pro kit from a member here, and I was wondering if it is worth the buy?

I am asking because my car has approximately 45,000 miles and it does NOT have sports suspension; My concern is that I am buying springs and will end up needing shocks down the line. I have done some reach and I believe Koni FSDs are the route to take.

Would it also be recommended to buy the e36 bump stops from BMW if I were to change my springs and/or shocks?





Thank you for your time.

From what I can remember KONI FSD are perfect for the pro-kit. But if you decide to ever change springs out then KONI Sports would probably better.

The ride with the pro-kit and the FSD seems to be a firm but not knock your teeth out. Bumpstops are not really needed with this setup as well. But other people will chime in very soon.

It's nice to be a long time community member, but it's even more great to actually be able to modify my vehicle.

Thank you for responding in such a short time, I was hoping you can elaborate on changing my springs out: Do you mean changing the Eibach Pro kit or OEM?

Thank you for your time.
If you are putting on the eibach springs, you should also change your struts and shocks at the same time. Either koni yellow or bilstein b8. If you go with the koni you should get the shorter bumpstops.

I am buying the springs for $120 brand new, and I was going to use my stock shocks until they went bad and go for coilovers.

If this is a bad option, should I try to get someone's sport or m sport (not sure if there is a variation between ZSP and ZPP SUSPENSION) shocks and put it on my car?

By the way, do you folks recommend the struts and shocks to be replaced?

Thanks again.

If interested; I have a set of oem Sport shocks/struts with hardware and bumpstops with just 20k miles on them.

Im running lowering springs and still running stock shocks
Works perfectly fine but they will need replacing eventually
I would avoid the FSDs and go with Koni sports adjustable shocks (koni yellows)
they are shorter than other shocks and perfectly matched to operate with the lower springs
Ride will be firmer than stock but no where near as firm as coilovers

I stay go with the springs on the stock shocks and when you feel up to it put in a set of Koni yellows

So you recommend waiting or should I buy someone's sport struts n shocks?

Buy some springs and wait till you get some decent shocks. Sport springs have a similar spring rate to sport springs, but the eibachs are lower. No point in doing the labour twice. And no point in halfway upgrades.

What is a decent shock? Not oem sport. Koni yellow's or bilstein hd/sports would be, in my opinion, the way to go. I did bilsteins with oem sport springs and couldn't be happier!

Good luck and merry xmas!

Merry Christmas!

I have an automatic non-sport LCI N51 328i, so will there be much of a difference upgrading my stock struts and shocks to a e92 ZSP setup?

Read up on the value of oem sport dampers. There is a reason people take them off and throw them out.

I would swap the shocks out more than anything. I had the Bilstien B12 kit installed. It had the Eibach Sport Springs and Bilstien B6 (?) shocks. The ride was pretty firm, a bit too much for New York's shitty road maintenance. I swapped the springs out for the non sport one's and I got mostly the best of both worlds. The car still handles firm enough, yet adsorbs the bumps adequately. I believe a M3 sway bar will set this off nicely.

If I still lived in Florida this might be a different case.

Dampers are different than bump stops, correct?

*Keep in mind I know almost nothing about how vehicles work*

Furthermore, if I were to install shocks and no springs - then I would be stuck with non sport springs and virtually no drop.

I suppose it would be best for my suspension to get worn out and swap it out for coiloivers (which I am hoping someone will sell me a used kit for cheap).

From my research, people either go coilovers or springs/shocks
Coilovers are adjustable so you are able to set the ride height but generally give a firmer ride

Springs/shocks come in different sizes and provide a fixed height (ie generally you cannot adjust the ride height). Springs and shocks should be paired together so they operate correctly, (ie short springs with short shocks and long springs with long shocks)
Lowering springs are designed to drop the car to give a lowered stance, they should be paired up with short stocks that are designed to operate with lowering springs (eg Koni sport adjustable shocks = Koni yellows)

Suspension is all about trade offs between comfort (firmness) handling (body roll etc) and appearance (drop). In short it is best to decide on what you want to achieve and get the parts to suit

For example
Comfort = OEM springs and Koni FSD
Sport = Bilstein pro kit
Appearance = H&R lowering springs and Koni yellows

Plenty of combinations but my advice would be to plan what you want
Suspension setups are a personal thing and there are plenty of threads on the forum covering suspension set up and what people find work best

One thing to keep in mind there is no single set up that provides a soft ride, low stance and on rails cornering... If anyone has found one please let me know

I would go with Eibach and Koni Sports. With the FSDs, it can either be too soft or sharp depending on how bad the roads are. On smooth roads, it feels great but in Los Angeles that doesn't happen too often.

I appreciate everyone who chimed in; I will probably purchase the springs and have them installed and aligned for $100-$150.

I'm pretty sure if you go on the Eibach website it states the pro springs are designed to work with the standard shocks as they don't lower the car very much, I wouldn't fit them with old shocks though. I did however fit the pro springs with new m sport shocks last summer & I'm very happy with the ride quality as a daily driver.
