I was looking around for diffuser and came across this one pretty interesting looks like rx7 diffuser from shine auto but been modified a little to fit 350z.

Looks like it requires cutting center section of the rear bumper.

Not bad-looking, but I think you'd have to be careful about the fit with some exhaust systems.

 

thats always been a 350z diffuser.. not sure where youre getting the r7x thing from...

 

i think you got mixed up with the top-secret diffuser.

all show you the difference between the two

 

rx7 diffuser :

sharp edges , deep tunnel , high raise

 

top-secret diffuser:

smooth edges , low raiser

 

different manufacturers... different designes

 

Different style yes , but both manufacturing by grams styling .

I thought guys how want more aggressive look might like it and it's not as common as top secret

 

all I can say is that there products are well done...so far! I ordered the do luck rear diffuser, which they are offering, for my Supra and the quality of the fiberglass looks good. didn't test fit it yet, to see how it actually fits

 

so after test fitting the do luck diffuser on the Supra I have to say this product sucks *****! the quality of the laminate is horrible, there are several bubbles in the laminate which weren't soaked with resin! I had to trim the part a bit to make it fit the exhaust and now I have several areas which I have to fill with resin to close up the holes.....besides the fitment is pretty horrible. so I would consider pay the money if u want a quality part

 

Thanks for your input, shine auto make same rx7 diffuser to build it on 350z would be a great idea

 

i guess with a little work u could prob. get every rear diffuser fit the car, all you need are custom brackets to fit it...imo
