So I decided to make myself a splitter for the Kouki. I decided to use this 3mm aluminum double faced plexiglass because it is quite strong, barely flexes and doesn’t weigh too much.
This material is $140+ 4’X8’, but I needed 1.5 sheets for another job, so I made sure I had piece big enough for myself when laying out my cuts.
The leading edge should sit 2.5" ahead of the lip, 2" in the corners and taper down to 1" at the rear most edges.
this is just the preliminary cut, I will have to trim the backside at the wheelwells, and hopefully the front main pully. As well as cut outs for the TC brackets.
I will likely mount it to the lower rad saddle, frame rails and somewhere else, using plastic spacer discs on fairly long bolts so I can create the desired angle
I may use FG to mould this into the bings lip, or I may use something to fill in the windage gap between the lip/splitter.
Anyways I hope to finish my mock up on the chassis this week.
bahahaha… in my windtunnel, I tore out the backwall of the garage where the it meets the kitchen, and installed a turbine engine and smoke machines… now I just need to make the garage a tunnel, and not a rectangular box.
What I have read so far indicated that on level ground I want the splitter 3"(roughly) off the ground, and 0 degrees or so.
I’ll update as I go… give me 7 days, it’ll be fitted.
Feel free to post links to other info that may halp me
a thorough read through the first post would have told you I plan on mounting it to the lower rad saddle and frame rails utilizing plastic spacer discs to achieve the the angle and position relative to the bumper/mounting points.
You mentioned fiberglass molding the splitter to the lip. I don’t know how low your car is but wouldn’t it be beneficial to not mold it, just in case you catch it on something. You will probably still damage the lip, but atleast it should be repairable, and you wouldn’t have already spent the time molding it. You could try putting foam or rubber in between the lip and splitter to seal the gap and stop air flow.
^this is looking more like the solution… but even moulded, that aluminum/plexiglass won’t flex much and or will add substantial strength to the lip, however it may be too much, to the point the splitter will rip the FG lip from the bumper, I may require sandwich plates here like the OEM S13 lip
why, If i wanted a carbon fibre one I would have ordered a $400+ universal one. This alumunum Plexi is going to hold up better, at a fraction of the cost, materials worked out to be free as scrap from the 2 4X8’s I used for a sign.
the weight difference will be minor,
NO to CF. Since I have zero tools/equip to vac form CF
