hi all brother here,

my friend and i plan to change our spring to lower spring!
our aim was ultimate comfort like original

i hear Eibach prokit is the best choice is it???
but after i survey few accessories/performance shop
many of them claim that the GAB, tein will also give the comfort feel (but i don't believe)
and i search the tanabe website and found that the tanabe NF-210 (not GF-210) only increase 5% from original spring (and will give ultimate comfort for the ride)

that's my survey

so i need all taiko here to help me to select the spring i need to buy

and somore, i donno where to find the tanabe NF-210 and eibach prokit in JB
any taiko know where to find the tanabe NF-210 and eibach prokit in JB

thanks alot thanks
