We actually used something even cheaper but i cant find it on google. it was basically kind of like a high density fibreboard composite panel. its kind of like foam but it was almost powdery when u cut it and not spongy like foam. and then we threw a layer of fibreglass over the top of it.
My whole splitter which goes all the way back to my subframe weighs prob 6kg incl the mounting bracketry
No composite material will come close to the price of alumalite. I don't intend of change that until people come to me telling me they're will to spend at least $3k for a splitter. This alumalite piece with all the brackets will weigh right around 7kg maybe a tad more. I think that's pretty damn good for not using expensive exotic materials.
All the bracket hardware has 2.5" load distributing washers at each bracket. There's no chance of anything getting pulled through the material. Not shown in the photos on the doc are 4 support rods that go to the front too. There are 10 total mounting points that all go to the frame/subframe. If the splitter can make enough force to flex 10 steel and carbon brackets then I'm doing this more right that I thought lol.
Here's the fiber reinforced rods. They disconnect without any tools so I'm pretty pumped to try them out!
It uses a compression ferrule to clamp on the rod and the rod can be trimmed to any length easily with a dremel. The structure of the composite allows tons of strength in tension (when it's being pushed downward by the air) but has lots of give in compression (like when you hit curbing on track) so you get the best of rods and cables. Also, here's one rod holding up an engine in case anyone is doubtful of their strength 🙂

I like "no tools". Hopefully I can come up with an ingenious way to mount the rest (using pieces I can find on my own) so I can get it on and off the car relatively quick.

The rest is just 6 bolts. I scraped the quick release idea after talking with some guys who designed aero for years and it's pretty much impossible to have a quick release that isn't load bearing.
Petty much. That's basically how I mounted a tow strap. My bumper cover flops all over the place without mounting to the crash beam...plus I "occasionally" drive on the street. For those reasons I keep the beam.
Until I learn to weld and make mounting tabs for the bumper cover, anyway LOL
I mounted my tow strap the same way. I was thinking of doing something similar but extend the mounting forward so I don't have to cut the bumper. Similar to this picture.

Reason: add photo
Okay, perhaps a stupid question for this thread, but in NASA TT, is it worth considering running BTM aero and getting the extra points for it? I have no aero on my car, other than having added a stock wing (which I could easily remove), so before I go down this road I'm just wondering...

No. BTM is only for TT3 and 4, but I'm guessing you're looking at TT3. Without a wing you'll have a tough time keeping the car planted. High speeds will feel unstable and it'll more than likely understeer pretty badly if you're using a grippy enough tire.

Okay guys I'm taking orders on splitters now. I'll have some more pics of the finished setup on Marc's car later this week.
Here are links to the descriptions for options and FAQ as well as the order form. I'm looking to build splitters in batches of 3. Right now I already have one order in que so once I get two more i'll be doing the first batch.

I do not have a price list as they're all built to order. A fully optioned out one would be right about $1050 + shipping. If you take off diffusers, skid blocks and endplates which would result in a pretty basic splitter it'd be around $650 + shipping. Those are just rough numbers, give or take $25.
