We are now offering a bolt-on rear diffuser for the 3000GT and Stealth. It is NOT a universal rear diffuser, it is fitted to the dimensions of the 3/S. They are available in CF and FRP.
Pricing is as follows:
FRP (fiberglass reinforced plastic) - $550
CF (carbon fiber) - $700
It has been tested on a slammed 97 VR4 (tucked wheels), with minimal clearance issues on every-day driving.
(We have not tested the install on a 1g 3000GT rear bumper, or a stealth)
It butts right up against the gas tank, and extends all the way back.
There will be some cutting and grinding required (you need to cut the "lip" off the rear bumper, and some trimming to the sides of the diffuser if you wish to retain your rear tow hooks).
We will supply all of the mounting brackets and hardware.
Here are some installlation pictures. The rear diffuser was originally installed on a yellow 97 SL that we converted to AWD and Twin Turbo, and we just transferred it to our customers new 97 VR4 (hence the scratches on the diffuser).
Anyway, onto the pictures/install:
1) Cut off the "lip" on the rear bumper
2) Line up the diffuser for bracket install.
3) The diffuser is pre-drilled for mounting holes for the brackets, so, you will need to line the brackets up with the holes, and mark the rear crash bar accordingly. We used a marker to outline the bracket to make it easier. We did not pre-drill the brackets because every car is different.
4) Remove the rear diffuser, and mount the brackets. Use the self tapping bolts to secure the brackets to the crash bar
5) Mount Rear Diffuser to brackets.
