Compare to other aftermarket springs with a much different design. But hey I could be wrong, Dinan usually puts out good stuff.

The stock front springs are linear. The stock rear springs are 2-stage (I guess you could technically call them progressive but not in the traditional way).
Both Dinan springs are 2-stage, but behave linear under most operating conditions.
Other options on the market from what I can gather are straight progressive. Lots of articles out there comparing the 2 styles but Dinan has always opted for linear style springs for a couple of reasons— predictability for one but also it rewards the driver with the most driver feel/input. Both are what you would desire for spirited driving and driving enjoyment in general. In regards to ride quality— paired with the bumpstops— stock suspension travel is retained so ride quality is largely unaffected. Generally speaking we have used the same suspension philosophy for decades and the press reviews are pretty consistent in that regard with glowing reviews and usually what is raved about the most. The X3M in my opinion is no exception to this.
