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 F56 MINI Cooper 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 0.75" (20mm) in the front and rear
• 33% increase in spring stiffness in front and 38% in the rear
• Substantial reduction in body roll
• Preset to prevent spring sag
• Includes (2) front linear rate springs and (2) rear dual rate springs (Ride Quality and Handling Kit sold separately)

 

Has anyone tired these springs out ?

 

Kudos for offering / recommending the new front bump stops along with these. That makes me believe Dinan is seriously dedicated to getting things right.
---------------------------------------

Three questions:

Good for 2024 as well?

Any limitations with the F57? I ask because some other springs say the F57 is limited to only 1/2 drop in the back, due to a thicker brace, or something like that. - And if that's the case, can the front be adjusted to match with shims, or will my F57 end up lower in the front? (I hate that look.)

And the big one: Does it work with Dynamic damper system? I assume, yes, since you sell the aftermarket bump stops, but I'd feel better with a firm confirmation on this.

--------------------------------

Also, although this isn't really a concern, I'd like to understand: The front springs are linear rate, not progressive. I thought progressive was better, though that's only based on what "some guys on the internet" say, so I really know nothing.

Obviously you guys didn't go linear to save cost, but because you think that's the best design. Can you tell us the reason behind this?
(Do others only go progressive because they're after more than an inch of lowering?)


- Thanks.

 

One more question, but the answer is extremely subjective. Still, I'd appreciate your thoughts:

This system obviously makes the suspension more stiff, which is great for handling & control, but what about ride quality?

If installing these springs and bump stops on a JCW 3-door that has dynamic (adaptive) damping, and driving in MID mode, will the ride become noticeably bumpier? (In sport mode, I don't care since that's part of the overall expectation anyway.)

 

1. Good for 2024.
2. Works with Dynamic Damper system.
3. Never been tested on the F57 (Only F55/F56) so they are not listed as compatible for the F57 but given BMW/MINI history I would be shocked if they physically would not fit. The problem is given the additional weight in the rear the car would likely have a reverse rake and sit a bit higher in front than the rear.
4. We use linear springs whenever possible as they are far more predictable and give the driver the best possible feel in our opinion. With a static rate the driver knows exactly how the car will behave when going into a corner and into, or out of, load before you do it whereas with progressive springs with a variable rate it is much more tenuous. From a motorsports perspective, and where we largely base our suspension from, predictability and performance is king over a targeted lowered ride height or comfort. That's not to say those items are not important but from the spring viewpoint themselves the performance is the driving development factor. The actual drop itself is never targeted, its just a result when all is said and done. In some cases its an inch or more whereas in the case of the old E9x 335i's it may be only 1/8" drop. Whatever reduction in ride height we can get away with for a flatter plane and limiting of body roll while retaining the same overall suspension travel as stock (for theoretically similar ride quality) is what is done. Sometimes the factory leaves lots of room to work with, sometimes they don't.
5. Ride quality is a bit stiffer but I would not consider it jarring or overly stiff (regardless of mode) as the same stock suspension travel is retained. The key in that is really in those extremes limits of the range where "comfort" is truly affected. This is where the bumpstops come into play and are often ignored or even worse, modified for further detriment. What most seem to ignore is that the bumpstop is part of the overall spring rate and for all intents and purposes should be considered part of the spring. When it is not in sync/paired with the springs you introduce a portion of the spring travel that will be jarring. Dinan matches our springs with equal rate bumpstops so that transition when the spring is fully compressed and the bumpstop is introduced is fluid. While they could be used with other springs they will leikly not be perfectly in sync so benefit will be reduced. Same can be said with re-using the factory bumpstop. The worst thing you can do though is modify the stock bumpstop though --- the variable rate inherent in the bumpstop is destroyed and that transition from spring to bumptop under poor road conditions will be very abrasive.

 

Has anyone installed these yet? Curious to know how the factory shocks and struts hold up to lowering springs.

 

Thanks, DE. Great response and very clear.

It would be great to know for sure about the F57 rear, if in the future you get empirical feedback from an end-user. However, the stock F56 and F57 are a bit lower in the front to start with, and as I wrote, I hate that look. So your springs might actually make the F57 look better.

Something folks should also be aware of, in case they aren't, is that since these springs "only" lower 0.75" (which still looks great IMO) there is less effect on the scrub radius. For anyone both lowering and going with a wider wheel, that additional benefit is something to consider.
