I went through the whole suspension board and heard go things about koni's, aslo about bilsteins. Koni's are good, and a lil bit cheap, bilsteins are good but a bit more expensive. My question is what should i go with? i drag race on weekends, daily driver during the week. And what type of koni's should i got with (red, adjustable, sport-street) or bilsteins (hd or sport), or should i try something else?
