Has anyone use tein basis z coilover system?
 

And how was it? Ive been looking into rce yellow spring + bilstein b6 as i heard its good for daily and performance 🤔

Theres a decent compilation of suspension setups that have been reviewed on here, best bet is to search in this forum for the answer your looking for. IMO the teins (im assuming you just mean the basis coilover NOT the flex Z) are fine if you want the aesthetics of a lower car with SOME performance. Running a coilover with dampening adj. makes a big difference if its a daily so you can soften your ride if you want and the basis only has height adj. you also have to use your factory top hat which can be a issue for some.
