Whats going on ya'll, I'm just doing a quick write up on how to install a rear diffuser. The install Is pretty straightforward, but ill just show how I did it.

The diffuser comes in 3 pieces and already comes with grooves so you see where you should drill through.



1. First thing I did was drill the holes in the grooves on each piece.
2. Second, Mock-up of side piece hugging the body with my hand a putting tape on it as shown in pic.
3. Drill in the hole while holding the side piece
4. install nut and bolt
5. Do the same to the other side (Mock-up and drill)
6. attach bottom piece with nuts and bolts, jack it up using the rx7 Jack and a 2x4
7. Tape center piece to bumper and drill
8. install but and bolt to center

Heres the list of things that I used for the install:
1) Stainless Steel Nylon Lock nuts 1/4 in- 20
2)Machine Screws 1/4 in- 20 x 1/2 in
3) Washers 1/4 in
4) ThreadLock Red
5) Tape
6) #6mm Steel drill bit
7) Drill
8)Screwdriver
