at the end of the day it does the job pretty well, and is a very good cooler kit for its price.
If you are going to buy a Greddy one, you know you are buying a quality item - it'll always be voted better of the two kits.
I bought the justjap one as i wanted to use of the standard ic plumbing in the engine bay. no cutting holes anywhere for pipes, no extra piping under the bonnet at all, no removal of my washer bottle. Simply less stuffing around.
yeah the 'gay pipe underneath' does sit a little low. just got to be a little careful, that is all. If you can drive through dips and reverse out of risky driveways in the right manner, you will be fine. carelessness will destroy these fmic kits, end of story.
