as the thread title says, are they worth the money? will I see that much of a gain from itb's if I run them in a k20 jdm itr with about 12.0 :1 to 12.7:1? i will like to run more towards 12.0:1, but anyway, will i get a lot out of it? this will be in practically a full motor build up if i decide to do it. thanks!
