what color was it unpainted...

 

white! (fiberglass is usually white,yellow, or blue)

 

Did you put it only using double sided tapes or did you screw it in? Did it have the holes for the screws in the oem spots like the nismo does?

 

My KurumaZ rear diffuser came with 2 pre-drilled holes for the OEM clib, my body shop drilled additional holes toward the 2 sides and fasten it with their own clips. The 3M tape is only applied along the top side (toward the license plate). They also had to change the license plate bolts to longer ones.

 

My shop used double sided tape, as well as screws in the oem spot , and four screws underneath. (all holes already in the diffuser) I guess you could get away w/ out using the screws underneath but I did it so I woulnd't have to worry about it sagging.

 

can you post some pics of this kakumei diffuser?
