So basically. Complete failure. This is my worry about going with a DIY approach. As much money as we save from the home made approach can be completely wasted with a simple flaw in design when the splitter ends up embedded in a Prius front bumper.

 

1/4" 5 ply baltic birch plywood. Very strong and light. Basically stiffer and lighter than most anything short of dry carbon.

 

Agree on plywood. Make a foldable templete and if you break it just bring it out and cut another

I would develop plates vs your turnbuckles at the radiator. There is a bolt on each side you can use as well as the radiator support

 

I wouldn't say complete failure. I learned a lot. The next one will be easier and faster to make. There is no success without failure.



Yes. Thanks. When at the track yesterday, this was suggested.



I was thinking this also.

 

I picked an option. Stay tuned for the pictures and results in a few weeks. Hope to have it done by June 22 track day.

 

This. And I second the recommendation of keeping a template so it's easy to make replacements. Put a nice exterior primer and flat black paint on it and you won't even see the wood grain.

This experiment wasn't a complete failure because I know the op learned a lot about his car and fabrication in the process. There's nothing worse than a fast guy that can't turn a wrench

 

Some pics of my DIY splitter project.
I used 1/4" 5 ply birch, routed the top edge with a 1/4 round bit, and painted it with bed liner in a can.
The splitter installs in 30 seconds and is adjustable in height 2", and also in angle a considerable amount. The plates on the chassis install at the top with the M6 bolts that hold the airbag sensors, and an M8 bolt that I drilled into the side of the lower Radiator support. So far it's held up very well, even through some muddy Buttonwillow offs.
Hope this aids you in your design.

 

That attachment bracket is bad ass. Looks like some machining went into that

Do you tighten the bolts on the slide on each time?

 

Wow! Very nice idea and execution. How do you access the bolts to tighten them, through the nose opening? Did you remove the stock undertray?

Can I post these pics on my website?

 

I think I had those brackets or something similar on my Type R splitter. Someone in Cali (I forget his name) was big on aero and made a nice splitter for Integras.
