i'm kind of stucked with some options for getting new struts/springs.
which of these are best combination in terms of performance:

1) kyb agx + neuspeed race spring (which i think lower than sports)
2) bilstein OE struts (non-adjustable) + tein S.Tech spring
3) eibach sportsline spring

feel free to mix and match. i heard koni yellow is nice but i can't afford it.
so yea. any opinions, would be great.
thanks
