Catching up on this thread. It is garden edging and they will have it (if they have it) in the garden section. Lowes or Home Depot should have it. Maybe even Walmart for that matter though I have never looked for it there.

Attaching the air dam to the splitter is not a big problem IMO, and there are significant benefits with overall structural rigidity and splitter support/stiffening.

 

I looked at every place in this village (40,000 people), so I ended up using fiberglass edging strip and so Dzus fasteners.

 

Even with that flat underbody and diffuser or was it splitter only?

Looks really nice. Especially the side sills and the underbody inlets for the front brakes. I think you could gain a lot by giving the air another way out of your wheel wells (back or top).

I test my aero around a corner every day coming back from work, its a one way corner out in the country. All speeds don't go under the noted mph

on 185 Barum Bravuris 2 no aero.............................................. .........56 mph
w/ 225 Nitto NT01 and no aero.............................................. ............62 mph
w/ underbody/diffuser/dive planes on 185 Barum Bravuris 2.............63 mph
205 Hankook Hankook Ventus HRII w/all aero...................................57 mph

The back is to happy to go any faster. I took it out to a 90 mph plus corner and at 90 the steering is way heavier than with out the splitter, but feels firmly planted. As for the wheel wells for venting is why I'm working on carbon GT style 30mm body fenders.

 

Took most of the front tires out of the air flow:

 

Here is a simple setup for making the splitter detach when you need it too without compromising on the rigidity of the mounts. When the nose of the splitter hits, the mounting bolts are allowed to slide in the channel you see, allowing the splitter to drop off underneath the car without causing any further damage. The kit is also simple to take off the car for those loading up the trailer. This kit is made by P1 Special Projects for the honda boys. I believe the mounts can be sourced seperately from the splitter and lip they sell.

 

Well kiss my grits! That's the cutest little thing I ever did see! But after a brief search it looks like that company just up and died. Does anyone here think they could make this their own special project and build a few to sell to us non-machinists? One that would integrate to the Miata frame layout, perhaps?

 

I think "KaZeSpec" was making something just like this over on CR. Thread was called "Full aero kits" or something.

 

Yeah kazespec sells a splitter kit like that for I think 350. Unfortunately he became a sponsor on cr and got tons of intrest in the kit until he finished it. That's when everyone decided they don't want it.

 

Sounds about right.

 

I completely forgot they made that kit. But now looking at it i remember why i forgot. The kit is overpriced at $315. I understand it requires them designing it and troubleshooting the product before releasing it to the public; which requires an initial investment of money and time. The hiems make the kit so expensive and the brackets are just simple aluminum pieces. This kit also does not solve the problem of breaking the splitter off in an o sh%* moment. The heims will rip off all their supports and the lower mount i dont believe will allow the slip needed to seperate the splitter as designed. In no way am i trying to knock Kazespec for their product and support their efforts to add a new miata specific product to the market. That kit just needs to be under $200 for it to appeal to the "diy" market.

 

Feel free to make a kit and sell it for $150. Why would a DIY market even be looking for a kit?

 

That's actually not how they work. They don't slide off the channels, you are thinking of it backwards. The channels are to allow the splitter to slide ON to the car so that it is easily removable. This kit doesn't allow the splitter to break off any more than the KazeSpec Engineering kit.

It's still a very nice design, would be great if they were closer to 200-250 though.

 

Give it time, the price will eventually drop in a few months when they realize they aren't selling that many.

 

Please stop armchair speculating about the merits of "breakaway" splitters. It's just the wrong way to do it. That is all.

Dollars spent: $220ish (excluding wing)
Hours spent: 20
How effective: 3
0=slower, 1, no improvement, 2 =slightly better,3= big improvement
Materials used: 12mm Marine Ply, 1 inch ali box section (3mm wall), 10mm ali plate, 3mm ali T piece, 3mm ali L piece, 2.5mm ali wire, various nuts and bolts
Bracket location: Splitter is to mounts in front of the rad
Tracks tested on: Llandow, no timing
Race/TT class built for: N/A track day car

Lessons Learnt:
Don't use a hacksaw on 10mm ali plate
When people say boot mounting a wing won't work, they aren't kidding
If you run with just a splitter, expect large amounts of oversteer

I haven't played about with the wing angle yet but at the pictured setting it balances the front aero nicely. That I can just keep up with the guys on semi slicks through the faster stuff is good confirmation for me that the aero is working well.

I do have slightly more lateral movement in the wing than I would prefer, any suggestions would be welcome, and apologies for how filthy my car is...

 

Use a couple of guy wires to make an X brace between the two wing mounts. Keith did it first: Targa Miata

 

Heres my attemp so far, just found this thread. Brilliant, going to try the plywood front dam next



Works off a switch on the brake pedal.
