Hmm, I used to really like the Koguchi fenders, but I'm not so sure anymore. I love the flared lip, but after seeing them on different cars, to me the gap makes it look like the fenders aren't a true part of the body. Does the gap actually go all the way to the wheel so you can see through it, haha does smoke come out when you drift? Don't mean to put them down though, the cars overall still look great.
From the front they look amazing.
From the rear I'm not really a fan of the gaps anymore.
I do love the BN Blister though, it doesn't need bright colors to be pulled off, Mad Mike's FD has been a recent proof of that, the car just needs to have awesome wheels and be low.
