ok, well to this date i think this mod is the one that i am most proud of cuz no 92x has it other than mine. maybe soon to change, but whatever i did it first. :biggrin: the photos arent super good but ill do what i can to explain it. its pretty simple, but ull hafta do some legwork to get the measurements all squared away since i didnt take down numbers. here it goes.
what youll need:
oem rear diffuser kit (subarugenuineparts.com 80 bux shipped) includes diffuser, rear bracket, and screws
go to home depot and get:
2 bolts that are like 2.5 inches long, and get the locking nuts to go along with it 7/16" should do it.
2 large washers, 2 small washers that will stop the bolt from going through the hole of the large washer, and 2 washers that will stop the nut from going through the holes in the diffuser.
1/2 inch pvc pipe
silicone caulking
metal primer
an electric drill and bits up to 7/16 inches
saw
Step 1

measure to the centerline of the vehicle and put a piece of tape or mark the spot
then put the bracket on the diffuser and measure to the center of the diffuser (between the four fins, not in the middle of the entire unit) and make a mark of the centerline of the bracket in perspective to the diffuser. then line up the two marks that represent the center of the car and the difffuser, and mark the two holes for mounting the bracket. then drill the holes with a 7/16" drill and deburr. also apply a spot of primer to make sure it doesnt rust.

now put the diffuser on and bolt up the screws to the bracket to temporarily hold the diffuser in correct position. go under the car and push the diffuser up so it touches the underside of the car. then use a light and a pen to mark the center of the holes in the diffuser to denote the points you will have to drill. note, you only need to use the 2 forward most holes, not the single hole in the middle. take off the difffuser and take the drill and drill the two holes as shown. then deburr them and primer the holes on the inside and out (did i mention you should take your spare tire out first :D )

assemble the bolt that youll be using with a bolt, small washer and large washer stacked on top of each other as seen in the picture sorry its blurry. then put it through the hole. the large washer will conform to the angle of the inside of the wheel well and the second washer will fit in the center of the large washer and be more or less flat. surely there is a better way to pull this off, but this was easy and it doesnt really matter anyways. this should be strong enough and once its tightened down it will be sturdy.
