Front Splitter and Bumper combo

I like the Stillen... some people had issues with dimples showing in the front but I don't have those issues. I have some pix on in my albums. It's one

How do you like the stillen fascia? Seems like it might be comparable to v1 nismo in terms of aero/ducting capability?
and you're right about the angle... Once I put the splitter on it points upwards appx 5-6 degrees so I need to level that off some. Also have the fangs with the front brake cooling kit too.

Yep, the splitter should be level or no more than 5* on a down angle. You be making lift which is no good! LOL

Yeah when I was over at Rusty's he broke out the digital level as he noticed it was off some. I'm planning over the winter time to get the full SPL kit and KW coilovers so once that's done and the car is lowered some I'll adjust accordingly.

So what are the two side vents for the stillen bumper feeding? I thought they were for brake ducts, but looking at the fang kit, it looks like the brake inlets fit into the main grill assembly?

It does look pretty mean though, and especially with the wrap color! I might try my hand at doing a wrap over the off season. Never done anything even close, but I'm not bad at painting, so hopefully some nuance and patience translates.

I think the Stillen bumper looks good. It reminds me of the Fugimura front bumper but not quite as sexy or as pricey. The reviews of the bumper is that fitment isn't always the best and can be a challenge and some have experienced a droop over time. The plus side is that it is one of the best bumpers for air flow and Stillen brake cooling kit works with it without any problems.

Correct... the fang kit in the main grill has the 2" hose kit that runs to the back of the rotor. The 2 big openings on the side just feed more air behind the bumper that flows thru the engine compartment.

When I bought my car new back in March 2014 within the first 3 months I was driving on PA turnpike of all places and hit a deer which damaged my Nismo bumper. At that point I said to myself let the modding begin.

Had it now 6 years and not a single issue. I do see all the negative posts on the looks and fitment issues but have yet to experience any of that.

Is the bottom of that stillen bumper flat across and back? Meaning does a splitter fit flush against it if it was just a flat board?

I've seriously been considering buying honeycomb and 1/8" birch to make my own structure, but if alumilite is as cheap as some have come by that might be a better option. I am curious how much the racebred splitters weigh since they're a birch honeycomb.

Thanks for all the great options and suggestions everyone! This will be a fun off season project. Can't wait to get this car back out there next year!! .

Ps, if anyone lives near tulsa, ok, there's a mustang club event at hallett this weekend. I wanted to make it, but my wife has to work and that means I'm watching our baby .

The splitter itself is semi rigid yet somewhat flexible. It's CNC machined aluminum composite. Here's a photo of the underside. The stillen bumper itself curves upward that small 5 degrees and this comforms to it nicely.

These guys over at Ventus Auto Works can do custom splitters or any variation you need as well. Not affiliated with them... just a one time customer helping out a forum member if you're interested.

Hmm, I wonder how he feels about the wood honeycomb sandwich materials. Carbon is definitely the best if you go with a nomex sandwich. I've worked that stuff before and it's really easy. Problem is at splitter size the pricing is crazy. You can make your own 4x8 sheet of the stuff for around 600$, though, but you need a perfectly level surface.

I have not weighed the splitter I made. It actually wasn't even a splitter, it was just a chassis mounted undertray. Mainly made it for 2 reasons:

A: Test the chassis mounting
B: protect my oil pan and bumper from getting destroyed because I used to do street driving.

That being said, I street drive it maybe 2% of the time, very seldom. The race group/class I compete in restricts aftermarket aero, so I will be removing my chassis mount and maybe saving it for the future if I bump up a class. You may want to look into a racing league (ie. Gridlife, NASA, Global Time Attack) and build your car to a specific class spec (if you haven't already).

Regarding the chassis mounting hardware, I purchased the battle aero mounting brackets. They are OK but under heavy load, I do think the two mounting points are not enough and cause flex in the splitter. I would make 4 additional mounting points on a splitter with the Battle Aero chassis mounting hardware (2 in the middle, and 1 on each far side).

So I'm talking to Professional Awesome about getting a custom cut piece from the racebred honeycomb birch and getting their mounting hardware since it's quick release (trailered everywhere). I'll have to do some fab work myself, but it shouldn't be too bad. Air dam will be fun...

I did the math on 10mm alumalite (which I read was recommended for splitter use over the 6mm due to flex) in the same square footage size as the birch splitter and there's a pretty massive weight advantage. 10 lbs vs 20 lbs. Carbon when done well is typically around 6lbs...so that's pretty solid.

So after more research on the racebred splitter, like most others it's a marine grade plywood that can be purchased in 4x8 sheets for 60-80$. This really doesn't seem worth it to me to spend 400$ plus 75 shipping on something I can make myself for <100$ and a couple hours of time. Granted, it's proving more difficult than I thought to find a source of marine grade birch ply.

I've been pricing out supplies to just make my own dry carbon splitter, and it's really not so bad. For that same 400$ I can get the majority of stuff I need and the work itself is pretty easy if you've ever worked with carbon or fiberglass before.

Anyone know of decent places to source marine grade ply, marine grade wood composites, or has anyone made their own carbon pieces?
