Custom Rear Diffuser, ST-205 Options

[Mani]

step 1:

make a base using hardboard



step 2:

measure and cut some MDF fins



set em at an angle of 7 degrees







Step 4:

add a bit of extension to ensure diffuser doesn't become an air brake



step 5:

take off and fastern all screws



Step 6:

Fiberglass the bastward with 2 layers



now i'll let it dry for 24 hours before applying and body filler

right, did some more fiberglassin.......



but whats this ????? 2 diffusers ?????



here's what really happened, used the wooden diffuser as a cast and made a full FG one, cause a wooden diffuser is to "BARRY", the FG diffuser is light as a feather, strong as steel......now gonna use some FG filler to smooth it out.......fits like a glove



the amount of sanding to do was astranomical.......anywayz, enough wingin

all sanded and smoothened



and all painted, cleared three coats but no pic of that, looks the same



looks sooooooo beautiful :wub:

looking at it, i feel as if i have made a baby :sofa: i want it in my living room, damn proud of it :wub: cant look at it eoungh.....

fitted pics









enjoy...i love it

I wonder if a homemade design such as this, without any tweaking to the base surface of the diffuser, could have any true aero advantage. I know Ray's does, but his company tweaked the contour for less drag. This just has strategically placed fins but is otherwise a flat surface. Looks sweet though.
