Dinan F32 435i xDrive Suspension NOW AVAILABLE!
The wait is over. Dinan F32 435i xDrive Springs and Bump Stops Suspension systems that not only transform the stance of the vehicle but also maintain ride quality and improve upon handling are what Dinan suspensions are known for. This is accomplished by pairing springs sets with bump stops, spring perches or both to maintain suspension travel resulting in a smooth ride while also improving mechanical grip and handling. This is what makes Dinan suspension systems unique. While we are able to sell each component separately it is highly recommend that both the spring sets and the supplemental ride quality and handling kits are used in tandem in order to maintain the Dinan quality standards our customers are used to. Experience the Dinan difference with this combination and enjoy the ride it provides. Dinan's Performance Spring set for the F32 435i (xDrive) provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the 435i by a 3/4" in the front and a full inch in the rear for improved suspension geometry and an even more aggressive stance. The Dinan springs are CNC wound with high tensile chrome silicon wire and shot peened for stress relief to last the life of the car. The 38% increase in stiffness in the fornt and 50% increase in the rear will reduce the rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving your car a more controlled feel. The Dinan performance springs will also provide a noticeable improvement in grip, for high speed driving situations that will inspire confidence in your car's capabilities. The reduced body roll makes the steering more responsive to driver input and will be noticed at low speeds up to the top speed of the vehicle. Benefits of the Dinan Performance Spring Set for the F32 435i (xDrive): + 38% increase in spring stiffness in front and 50% increase in the rear + Lowers the vehicle 3/4" in the front and a full inch in the rear |

Will this work for all 4 series xdrive? Why just f32 435?

Just the 435i xDrive. First and foremost we have not tested the sets on xDrive variants of the 428i or the Gran Coupe and Convertible 435i. They may ultimately work but I would highly doubt it given the weight differences, chassis variations, and other variables . While a one size fits all approach may work for some vendors that is not how we tend to do business. We engineer to each individual model car. |

I have Dinan springs for 335ix. I was installed springs in official dealer. He said that front axle with dinan springs not straight from gear to wheel. And there will be extra load on the bearing. This can lead to breakage. What do you think about this? |

Tl;dr - Get the Shockware at the same time as the springs if/when possible. You won't regret it. |

We have never test fit the suspension on a convertible so I couldn't say with absolute certainty but given the weight difference its a safe assumption that the rear springs / bump stops at very least would differ from the normal coupe variant.

Dear Dinan:
1) Can you please tell me your reasons for greater reduction in ride height in the rear (1") as compared to the front (3/4")? I've wondered this since reading that observation from those who have already installed your springs on the 435i xDrive. 2) Same question with respect to spring rate increase front (38%) versus rear (50%). Why the difference? 3) Would you consider the damping rate of the Bilstein B8 Sport shocks & struts to be suitably compatible with the Dinan springs for my 435i xDrive? I'm seriously considering switching to the Dinan springs on my 435i xDrive. I currently run H&R Sport springs with Bilstein B8 Sport shocks & struts. (The "Sport" B8s are intended for lower springs than stock.) The ride is generally much improved for spirited driving in all conditions EXCEPT a certain frequency of sharp bump (about 2" abrupt rise in street surface). When hitting such a short, rapid rise bump, I get a "SLAM!" as though the front end bottoms out. Others have reported broken front top hats when hitting hard bumps with the H&R/Bilstein combination. If the increased travel and presumably tailored spring rate of the Dinan springs will help to overcome this ride characteristic (especially since it seems they are specifically matched to the weight of the inline 6 in the 435), then count me in. Currently the ride height of the H&Rs is attractive, albeit with a slight "rake" (rear higher than front), possibly due to the one-size-fits-all approach to the spring set. But I'll take the higher stance of the Dinan springs if they drive and ride better. I'm eager to hear your reply. Feel free to PM your response if you prefer. Thanks much. PS: I do not have Adaptive M suspension.

3.) While we have never tested the Bilsteins I am sure they will work fine with Dinan springs. I seem to recall a forum member having the combo and raving about it but can't find it on a cursory search. The damping rate of the Bilsteins and the springs are obviously not going to be a perfect match as they were not specifically designed for one another like we like to do when we do a Koni/Dinan spring combo of the past but any additional dampening over stock would be a step in the right direction. |

Any chance you'll do a matched Koni/Dinan spring combo or some other such full suspension "enhancement" for the 435i xDrive, or is this (springs) probably it?

Update on my 435i xDrive with static suspension. I first added H&R Sport springs with stock dampers. It was over-sprung and under-damped, so I added Bilstein B8 shocks and struts. While it was quite nice on perfect roads, the ride was $hI7 when the suspension was under the slightest duress. On choppy, bumpy roads it "slammed" and lost composure. My driving became tentative everywhere. After 9,000 miles (yes, I'm tenacious) I gave up on the H&Rs and I've just swapped them for DINAN springs. It's night and day. The ride is now firm, almost stiff, but with a suppleness over rolling bumps and excellent composure over choppy, crappy roads. This, with 19" wheels. Mind you, I've got 1 1/2 to 2 fingers of clearance in the front and 1 1/2 fingers rear, i.e., it rides higher than the H&Rs, which were almost tucked into the front fender and 1 1/2 fingers clearance in the rear. While it's higher than it was on the H&Rs, it's still considerably lower than stock xDrive (DINAN says .75" front and 1" rear) and looks great. I'll take the renewed ride of the DINAN springs with Bilstein B8s any day. It's the balance of sporty performance and drivability I was looking for when I first began making changes to the stock xDrive suspension. Very pleased after 4 days of driving.
