I got my body kit from CarMate as that is where the dealer which I bought the car off said he could get parts from and he would get them installed and painted.
It looks great, can't comment on build quality as to me I am very novice and all parts "feel" the same to me.
There is some gaps where the parts don't exactly fit the car shape but that could also be from where the panel beater didn't take the extra time to make it fit but who knows.
I am very happy with how it looks on the car and the price. Only cost me $1000 for Front Skirt, Side Skirts and Rear Aprons (painted and fitted)... As I have a 4 door r34 I could not get alot of choices for sides or rears but fiqure go cheap for the first front skirt rather then the fancy nice ones I see on some other skylines.. You can see pics in my Album link. Haven't had time to take photos during the day or up close but you can see how it is not noticable the little bits where is slightly does not stick to the original body.
