Is there a consensus on Dinan springs?
I have looked at quite a few threads.
It appears that they do not cause issue with the factory struts. Can owners chime in with results? Happy? Do you track at all with them? It would be nice to have one thread with current results. The only negative I have seen is cost for the bump stops. Has anyone tried vogtland springs? Cheers |

I have Dinan springs, bump stops and the Shockware mod (not available for the 235i) on my 228i M-Sport. I do not track my car but I will push it on the street when safe. No problem with struts. I do not resent the cost of the bump stops. These suspension mods are the best mods I've done, tune included. The drop is perfect to my eye and, more importantly, the handling and driving dynamics are a huge improvement over stock. It dials out the understeer, enabling me to stay on the gas longer and with more confidence in sweeping corners where in stock form the car really pushes. I can feel so much more power being put down on the road rather than dissipate in soft springs and the car no longer dives on heavy braking, leans under committed acceleration or rolls when cornering. The way these springs handle lateral and longitudinal forces is really impressive; there's just no wallow left in the car in any axis and the handling just feels dialed-in; it goes exactly where I point it now, quickly and with no wasted momentum. Comfort mode feels pretty tight compared with stock but it's in Sport and Sport + that you will really notice the difference; the ride and handling are really tight and sharp but still civilised; there is nothing harsh about it and it remains refined.
Personally, I think it would be foolish to exclude the bump stops on the basis of what Dinan is charging for them. If you go for a Dinan suspension mod, it would be a false economy to opt out of the benefits of an integrated package involving individual elements that they test extensively and which are designed to work well together. If I tracked the car and it was out of warranty, I would investigate more radical suspension mods like coilovers, etc., but the Dinan springs and bumps really hit the sweet spot for me in street driving and, as much as the tune, they bring out the aggression in the car that is subdued in factory trim.

I have heard nothing but good things with the Dinan Springs.
That being said, do not fool yourself over what these springs will/wont achieve for your car. The fact of the matter is that you will be putting mismatched springs on your EDC dampers. Will they still work? Sure. Will they reduce your strut life? Probably. Will they make your car handle like a LMP1 car? No. Frankly, the results BarryJI had with them are probably more due to the Shockware than the spring hardware (could be wrong about this, but that's my guess -- I really, really wish Dinan could crack the suspension ECU on the M235i/M3/M4, which all use the same module/coding). Shocks and springs do affect body roll, but the more appropriate suspension upgrade for body control is/are sway bars, which are very cost prohibitive for the install. That being said, if you want a safe drop with minimal negative effect on handling and shock/strut life, the general consensus (I think) is to get the Dinan Springs with the shortened bump-stops, whether you get them from Dinan directly, or from some third party.

I appreciate the synergy between shocks and springs. At 10% stiffer it's a 10% greater ask of the shock to control it. If the results have been positive and the life of the shock is only reduced by 10% that's manageable. If it's too great a chore for the shock to control the spring then it's not worth it. My expectations are reasonable as I expect handling will only be slightly improved. As long as it's an improvement I'm happy.
I am curious as to why the larger drop in the rear compared to other spring solutions? Thanks for the feedback keep it coming. |

What larger drop are you referring to? Dinan drop for my 228 was half an inch at both ends.
I think you can reasonably expect a very significant handling improvement, not so much because the Dinan kit is so good (although it is pretty damn good, for the street anyway) but because there is so much understeer, roll and general softness built into these cars, which, for most people, represent luxury more than performance. Being able to dial out all of that gives you the handling of a true sports coupe vs. a luxury coupe and is well worth doing by any available means.

For those concerned with price on the bumpstop kit, theres a cheaper option than ordering them directly through Dinan: http://www.2addicts.com/forums/showthread.php?t=1237935

To me: On the Stock setup, overall ride quality for both the Comfort and Sport Chassis settings were nice and comfortable, but body roll was very noticeable when turning at any level of speed, which was dialed back a bit on Sport. The ride quality on Comfort with the Dinan kit (no software) is STILL just as comfortable, but that comfort now extends to cornering as well, in the form of much improved handling, (even over Sport on stock springs). I also don't feel that much of a difference in ride quality between the Chassis setting (leaving the Drivetrain setting the same), which is fine because again they are both great. The biggest difference in the Sport Chassis is still the heavier steering wheel - which I love on the highways. --Not to mention the drop looks absolutely perfect - to me it's how the car should've always sit, even at the base config level. That and the warranty sold me on the Dinan setup even with the slightly higher price point. I'll try to add some before and after photos for reference Last edited by Shashkastorm; 04-02-2016 at 12:23 PM.. |

Can't wait to install my Dinan springs and supplemental kit. It's just sitting there waiting for install, but I'm waiting on new wheels. Would like to install the wheels and springs all at once.

Definitely glad that I went with the Dinans and supplemental kit. Ride is excellent, ride height is perfect IMO. Transforms the car handling wise. Handling characteristics as stated by others previously in this thread are spot on. I think if you get much lower you will sacrifice ride quality and more significantly decrease the life of the stock struts. If I were to do anything else other than Dinan springs I would go full coil over. I included some pics I took with my 6plus today for reference. 19" HRE's 235 30 ET40 and 255 30 ET44 PSS.

Looking good! Glad you agree that the handling benefits are great. This has been a transformative mod for me. By way of comparison, here is my 228i M-Sport after the springs/bump stops were installed.

That's a great photo.The best I've seen posted on this forum.The angle and the lighting (and the springs) almost make the car look a new model. Good job!

This picture is when I had the Dinan springs on the car, IMO they gave the car a nice little drop and the car felt a little bit better. Hope this helps

Looks great guys!
I'm thinking for aggressive street driving. Dinan springs and camber plates would be the ideal. Slight drop and more even tire wear. The added camber in the front would balance out the 0.5' to 1' drop split as well. |

Awesome photos all! Here's my before and after photos as promised on an otherwise stock 2016 F22 228i (Non-M-Sport). The wheels are 17" Style 380 on the stock RFTs (sorry for the pollen / shadows - spring in Georgia is brutal!!):
Before: After Dinan Springs & Bump Stops: Like others have mentioned - the drop is by no means aggressive but the improved handling is much appreciated without sacrificing ride quality! |

Yes I do have adaptive suspension. Comfort feels a little bit more stiff than stock but seems like it reduces a good amount of body roll. Haven't noticed any bouncing. Sport feels connected and much more compliant with the heavier steering. It just tightens up and wants to be driven hard. TBH I haven't used Sport + because I recently added a JB4 and haven't had the balls yet it's been a lil chilly here in Ohio so isn't hooking up really well. IMO this car in stock form was just a touch too supple and the benefits of these springs far outweighs the rather minor impact on comfort. |
