Purpose is to create a wind shield when changing from a stock style suitcase muffler. This should stop air from getting trapped behind the rear bumper which creates a parachute.
I have the Borla exhaust which drops ~10lbs off the car. I know Borla has there own diffuser for their exhaust but it also adds ~8lbs back on. Negating the weight loss of the exhaust.
For the record I want to make this out of a sheet of Carbon Fiber. I would need a 2' x3' sheet to make. 2x4 sheets are $300 for 1mm thick. Crazy! If anyone can find a sheet cheaper please let me know
For this version I used Coroplast as the plate. I want lightweight,I have no idea how the coroplast will hold up. At least I can transfer the design if I find a better material to use
Materials used all found at home depot
Sheet of coroplast need at 2'x3' to work with
Threaded rods
Hollow aluminum tube
nuts bolts washers, fender washers
Total weight 1.5lbs
weighted everything at ~2lbs then minus everything I didn't use ~.5lbs
Parts on scale
Rods bolted up to stock heat shield brackets.
Now showing the aluminum tubes with fender washers giving a solid mount for the shield
Installed! The plate tucks inbetween the rear stock diffuser and mount. used the stock rear diffuser attachments just switched out the black plugs with bolts. Also cut the rod bar after everything was mounted.
An inside view
Have it up all the way to the rear subframe. Plate sits on top or the LCA bolts
