how much is the TEIN basic in the market now?

well i just want to car lowered to be honest. but its causing me drama because of the front suspension (like i always said its really high compare to the rear) the guys from ozzie tires told me if i drop it more than 2 inch, my strut wouldn't have enough travel space which worries me alot. and thats the time they told me d only option i can go is coilover kit (which is very expensive!!) thats why i keep asking u guys here to help me cause im a bit stupid when it comes to my car n i dont have much resources.
