Some interesting comments at Viper Alley discussing this. Might be worth reading both threads.
Dave here is my reply to you OUTBURST on the Alley, and yes they pulled the thread since it was my thread and you, for some reason went awol in it.
Dave,
I sold 2 splitters to Gen 2 guys who did not want to trim their fascias on the bottom as was required. I have also sold numerous splitters to Gen 1 and Gen 2 guys who say they are the best thing they had and increased their cars stability at speed (just like a splitter is supposed to)
This is a different product than what you are trying to make, and as you know,
since I emailed you a bunch of my schematics and concepts that I sketched up to you, that I have researched gen 2 splitters quite a bit. I am the one who told you it has to be frame supported and cable supported, not bumper supported.
I did look into Tegris, 2 years ago and recently, it is a fiberglass type cloth impregnated with a poly plastic that is resistant to bonding. Tegris costs $800 to $1000 a sheet (so I was quoted by Chris at Tegris), and while it is great for Nascar splitters that are supported in numerous places when used as a single sheet, it is not a stiff product unless it is made in numerous bonded layers, like how the Ferarri splitters are made. They are made of 3 layers of Tegris with cavities cut out of sections filled with structural foam and then they are bonded together at high temperature. this equates to cost,
"using CNC-machined pockets in a sheet of Tegris which is inlayed with high density foam and covered with a cap layer of Tegris that is then heat formed back into one piece, achieving a high level of rigidity."
Ferarri splitter
multiple rod/cable attach points Nascar
Tegris is great stuff, bullet proof in fact, and has a definite function in the race world but in order to make it
stiff like a splitter needs to be, it either needs to be structurally worked as in the Ferarri piece or it needs to be supported in numerous spots like the Nascar splitters are with 5 rods across the front and with 8 attachment points across the back.
I applaud you in your efforts to make a splitter for the masses and I am not making a splitter for Gen 2's as it requires the owner to cut their fascia and I already went down that track and found that when people are actually at the point of cutting holes that they do not want to do it.
Make your product and good luck, and I will make mine!
