Dinan BMW G20 M340i (RWD) Springs/Bumpstops

Part Number(s): D100-0934 & D193-0121
Applications:
  • 2019-2022 G20 M340i (RWD & xDrive)
  • 2021-2022 G22 M440i (xDrive)
  • 2019-2022 G20 330i
Product Page(s) / Pricing: Release Date: Available Now!

Description: 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 recommended 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 G20 M340i, G22 M440i xDrive & G20 330i provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the car 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 increase in stiffness 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.

NOTE: Dinan Performance Spring sets should be purchased and installed with the corresponding Ride Quality and Handling Kit to achieve the advertised ride height performance and ride quality. While not explicitly required, if the matching component is not purchased and installed you will get less than favorable results in the form of poor ride quality and improper handling traits. While we will maintain a full warranty on product defects any claims against the cars improper handling ride quality traits due to not purchasing the corresponding handling kit will not be warranted.

Features/Benefits:
  • Vehicle lowered 1" in the front and rear (M340i RWD & xDrive).
  • Vehicle lowered 1-1/8" in the front and 5/8" in the rear (M440i xDrive).

Dinan BMW G20 Tension Strut Ball Joint Kit (Monoballs)

Part Number(s): D280-0022
Applications:
  • 2018-2021 G20 330i
  • 2018-2021 G20 330i xDrive
  • 2019-2021 G20 M340i
  • 2019-2021 G20 M340i xDrive
  • 2021-2022 G22 M440i xDrive
Product Page(s) / Pricing: dinan.info/G20-TSBJ
Release Date: Available Now!

Description: An underrated component of a proper driver's suspension the monoball kit (tension strut ball joint kit in today's terminology), is a remnant of an era when road feel was something desirable and sought after. Drivers wanted the visceral feel of being connected to the road as the road-racing heritage of BMW M demanded. Dinan embraced this and over the years mastered its craft into a kit that not only satisfied the desire for proper road feel but also made it livable for everyday driving. While stock suspension properties may have swayed from its golden era lineage to more mainstream ideals, Dinan is here to correct those mistakes for those that want a more M-passioned BMW experience.

The Dinan Tension Strut Ball Joint Kit provides responsiveness you can feel by replacing the rubber bushings in the thrust arms with precision ball joints and machined aluminum housings. Improves responsiveness by eliminating the deflection inherent in the stock rubber bushings while also reducing brake shimmy. The quietest bearings on the market are virtually noise-free so you can live with them every day. These are the only bearings on the market that are sealed using a rubber boot to keep out dirt and road grime stopping them from wearing out prematurely.

Features/Benefits:
  • Improved steering responsiveness.
  • Reduces brake shimmy.
  • Nylon-lined bearings for quiet operation.
  • Machined aluminum housings.
  • Sealed bearings.

YAY! It sounds like these are compatible with the adaptive suspension option, correct?

Yes. Our car in the photo has the adaptive suspension.

Also a quick profile shot before it goes back in the air...

We currently do not offer any Dinan spacers although its in the development list to be done as we get closer to offering our own universal wheels. Historically we always did offsets on our wheels so spacers were never required.

In the case of our development car it is on stock wheels with no spacers.

Need to see one before we can develop suspension for it I'm afraid. xDrive models arent exactly common in the deep south and the development requirements dont lend themselves to make shipping a car in really a viable option.

Great news! Before I pick up a set of springs and bumpstops for my M340i, can you confirm these will fit the non adaptive suspension?

Unfortunately I'm over 1k miles away so can't help with that!

What can you say about the strut ball joint system that was also released?

The monoball kit is really targeted for guys that autocross/track their cars more then anything although if you drive "spiritedly" they definitely have value as well.

Basically it improves on the tactile feel of driving for lack of a better way of saying it. The improved bearings allow the steering to be more predictable and removes the delay in between the input (turning the wheel) and the output (the car actually turning). As a result you feel more connected to the road inspiring more confidence given the car behaves exactly as you are telling it in real time.

It's one of those parts that you see on paper and don't think much about but once you experience it you understand its value. Such is the life of a lot of suspension parts actually.

Someone actually had a really good description of monoballs that I can't for the life of me think who it was. Might have been Turner actually...

Dammit. I'd be all over these if they were xDrive compatible. I shall wait.

Scheduled my install for next week. I got quoted around 1200 to install everything (including the bump stops and the monoball mounts). They'll need a day and a half for the install.

Does that include alignment too?
