Dinan Springs

dleccord · 08-05-2017, 02:15 PM

What are the spring rates on these for our E90's? How much stiffer are they compared to the M-Sports springs and does anyone have any experience with these? Please share!

Dinan doesn't publish spring rates for their springs so it would be hard to get a definitive number there but what i can say about them is that they are most definitely stiffer than the M-Sport springs, not in a bad way though. They significantly reduce body roll while not making the ride to harsh.

In my opinion however the best springs you can get for our cars are the Swift sport springs, i have them on my car and there is simply no equal

But they lower the car much more than Dinan. Personal preference at this point but roads are bad over here and I scrape in certain parking lots even on M Sport suspension

Thanks for the reply!

They lower the car slightly more than the Dinan but in my opinion (which doesnt carry a whole lot of weight) the performance benefits the Swifts bring is worth it. Here is a forum members car on swifts:

His car looks a little bit lower than mine but as you can see it isn't crazy low. I live in New England with pretty much the worst roads in the world besides 3rd world countries and I don't scrape anywhere except for speed bumps and outrageous driveways

I have the Dinan Springs. They are stiffer, but the ride is not compromised. You notice the stiffness in a bad way at low speeds (20-40) on rough roads.

You might also want to consider the BMW Performance suspension springs.

Dinan are great springs if you want a firmer ride but do not want to lower your car.

Here is (left to right): BMW Sport; Dinan; Eibach; H&R:

Dinan are taller than Eibach, but firmer.

Op - 195/505 F/R roughly. I have the BMW ps yellow springs and consensus is they are about the same as the m3 stiffness, Dinan being basically the same as the BMW ps yellows.

Do the Dinan springs sit just as low as the M-Sport springs?

Asking for a 2011 E90

They are the same in rear and another 0.5" drop up front.

Thanks for the answer! What about the BMW Performance Suspension Springs that someone mentioned earlier above, how does the ride height compare to Dinan? And what's the difference between them?
