So after reading Rob's website for the up-teenth time, and some of the corvette and porsche websites, it seems most folks will run a custom plywood splitter and I am thinking of trying it out. While birch seems to be the go-to, Im wondering if oak or another hardwood has been tested? Obviously we'd want it light, but not flimsy. Is birch the optimal choice? Or is another species better?

 

I don't get it. Wood is heavy and susceptible to water logging. The only benefit I could possibly see with this material, is if you crash the car a lot and need frequent inexpensive replacements. I use aluminum. Though it isn't the cheapest material to work with, its not the most expensive either, and it last forever, is light weight and looks good.

 

Wood's density is typically about half of aluminum. If you paint it, seal it, and something to dress up the leading edge I don't think it would look half bad. But I would just save the time and effort and get a Low Pro Aero splitter. Very happy with mine.

 

Unless Im looking at the wrong pic, the lo pro isn't a functional splitter, it's a lip protector. Take a look at Ino20's avy, I need about an inch less than that (twss!).

I like the idea of making a template and being able to duplicate it without screwing the front bumper up. That's the thing about wood, it'll splinter before it rips the bumper off. Im also kicking the idea of Lexan around, but at the thickness Im thinking it might be a little too flimsy.

 

There is always Alumalite. The 6mm thick stuff is no joke.

 

I'm a firm believer in plywood splitters. Ive been making plywood splitters for my lemons car for years, and they get thrashed all the time. Total loss? $25 at most.

This is 1/2" finish grade birch plywood with gloss black exterior house paint applied with a foam roller. Used a router to bevel the edge. At 1/2" its strong enough to not need strut rods, as it survived the ACS test just fine.

 

Yeah I think wood is a decent choice. It is easy to work with and cheap. It doesn't take much of an off track to destroy a splitter.

 

I run a wood splitter on my s2000 because it takes a beating and is dirt cheap. Hell I scrape it more getting it in and out of my trailer then I do on track but at the end of the day its $25. I think I bought some 3/8" but I can't remember the type of wood.

 

So I've got the outline and the holes drilled...should I angle the edge down or up?

I just set mine level.

As long as it doesn't deform at speed, level is fine. The only reason I can see to set it at an angle is to compensate for rake change due to rear aero.
