Coilovers: BC Racing DS DA vs Bilstein B16 PSS9, help me choose

[Jpt23]

Opportunity has come up for me to source my coilovers at cost price after delaying purchase last year. I'm down to 2 options - after a final steer to help me choose. Price not really a factor.

Car sees road and track but is a weekend and track day toy only. Looking for reasonable road manners with good track performance. It's an 08 e86 z4 3.0si Coupe.

BC Racing DS DA, 8KG front, 10kg rear (leaning towards these)

Pros:
Digressive piston, pillow ball fronts with rubber mounted rears, and adjustable camber plates as standard

Custom spring rates, flexible for changes later

Generally seems more customisable

Cons:
More budget option option/lower build quality, but I know bcs are still pretty well rated by users

Does 30 clicks of adjustment feel excessive vs 9 on the bilsteins? Wondering if ill end up preferring less clicks and more noticeable adjustments

Bilstein B16 PSS9 (like the quality but have some hangups)

Pros:
Primarily build quality and brand rep

High quality inverted monotube

Cons:
Does not come with adjustable top mounts and solutions will be aftermarket - unclear what will fit

Bilstein don't seem to share their spring rates/seem less customisable

No digressive valving and have heard feedback billies can be very stiff and bouncy on these cars from quite a few users, not so tolerable on road?

I’d pick the bilsteins. I run B8’s on my ‘03 and they are great

How about a set of KW Clubsport?

I bought a set of BC coilovers recently for another car. They are OK but not the best quality. I think they are sold as another (cheaper) brand with a coat of yellow paint.
I didn't have much choice, as not many make aftermarket suspension to fit my car.
So basically, as far as I can find out, BC are generic Chinese parts branded by different people at different prices.

We also have a car with KW coilovers on (from the factory). These seem a lot better quality and much sturdier built.
