Tein Flex Z vs ST coilovers
 

I’m cross shopping the two. Prices are about 150 apart. I’m mainly using it for lowering and accommodating wider wheels down the road. I seldom track my car, just occasional canyon run and it is not my DD. I want something comfortable and not making clunky noises. I know ST is not damping adjustable, hows the preset damping compare to stock ride? Is Tein flex z more harsh to ride on compare to ST?
