Hi,
Im building my R34 gtr also I used the r-tune bonnet , i did not want to use the aftermarket bonnet as it was so weak i could see it coming off my car. I bought nismo fenders as i had bought alot of the kit from Josh but was extremly disappointed with the quality. Any aftermarket fibre glass kits you have to but it from Bodyform, he makes the best quality .
Below is a link you can see how the kit looks on my car.
