The Dinan springs are amazing for this pricepoint! It feels like the M inspired car that it should be.

It's hard to distinguish the difference in springs alone as I had new wheels and tires done at the same time. The bodyroll and turn-in is significantly better. The steering feel is greatly improved (maybe more from the PS4S).

They are still settling, but the ride height and stiffness for me is perfect. I do still need to use the car for normal things. They are firm enough to handle, but not too much to give you poor ride quality. It still feels comfortable on the road when you need it to.
