I bought the FK7 vents for my Type R and they did not fit, the outside lower corner would not sit flush like the stock parts. Didn't try modifying them because I wanted to be able get my money back if they didn't work.
I can get it much cheaper through my job so let's get rolling here bro lol you won't have to bother with it. And like I said just sandwich it with some flattened boxes.
I'm at 30k and all of my pads are almost at the squealers, no track days. Car is pretty weird some times, like how everyone seems to kill their stock tires at 15k miles and mine were still brand new around then.
