But, for me KW priced their v4 for the F90 beyond what I wanted to pay. Although after driving the stock base model for a few months, I realized BMW had refined the handling of the F90. I don’t know if it’s the change to AWD or actual suspension changes, but other than being slightly soft, the car handles much better than the F10. So, after looking at both KW and Dinan HAS systems I went with Dinan, and it’s done just what I’d hoped for the car. It is more firm than the base F90 springs, more like the comp F90 I test drove briefly.
I don’t know if BMW is using the same supplier for the F90 shocks as they did for the F10, but the F90 settings between the three firmness options seem more definitive to me, and the damping action much better. The Dinan springs don’t over power the damping and the ride never becomes bouncy. Dinan does include 8 of what they call “suspension packers” to fine tune the clearance on their bump stops. Perhaps some of you are that in tune with the feel of the car to notice the change an 1/8” shim will make, I’m not.
The machining of the parts is excellent and the anodized finish is also first class. Adjustability is easily done and the locking bolt for the adjusting ring is very accessible. If you’re doing the install yourself, the instructions are clear and easy to follow.
When this picture was taken I wasn’t thinking of showing the drop, but the center of the front wheel to the fender is 14.5”, and there is another 1.25” of thread left to adjust the height lower if you wish, both front and rear. These tires are 1” less in diameter than stock, and the bottom of the Fall Line oil cooler guard is 4.25” from the ground, so this is as low as I wish to go.
I also installed the Dinan rear suspension link kit for long term durability, but at this stage can’t feel any difference in handling from that. The install is straight forward with pretty basic remove and replace steps according to BMW procedures.
Again, for longevity reasons, I’ll probably also eventually use the tension strut ball joint kit from Dinan for the front, but haven’t made that purchase yet.

That red side grill is distracting me from looking at anything you did with your suspension.
