the aim would have been to use the exisiting undertray mounting holes and be within the pivot area.

I don't have a drawing, but I do have a coroplast undertray that you can use as a template to get the drawings... I use the existing undertray's mount points on the subframe and the bumper (ie just before the oil pan, and bolts directly to 5 bolt holes on the bumper).

Is bolting to the bumper structurally sound enough for a splitter? I was under the impression any deflection in the splitter would drastically reduce effectiveness. Granted This will be the only aero on my car so far so it may not matter much but if I am going to bother with it at all, I would like to know it has potential to do something. I have seen turnbuckles used before, is that overkill?

I would prefer the splitter be the rigid point to use to mount an airdam to, rather than use the bumper/airdam as a mount point for the splitter.

But I would like to come out and see what you have done just to see.
What part of Raleigh are you in?

definitely not structurally sound. Just saying that as a reference for length. I use it more as a smooth undertray (I also hold it in place from the top, but its not relevant to this). You would need to extend it for it to be splitter. Turn buckles are definitely a good idea I think.

I am in the brier creek area.

The bumper + turn buckles is ok, but will stretch your bumper skin a bit even if you keep it under 70mph

Wouldn't the turnbuckles be preventing any downward deflection?

Yeah near the turn buckles. My splitter even with the big braces still flexes down and scrapes the surface especially with the extra bumps and grip of the nebraska concrete.

Seems like the Brain does not want to part with his .dwg file.

But if you have solidworks (or autocad if memory serves me), you can take the image Brain posted in Post #7 and add it to a sketch. Scale it correctly per the dimensions in the image. Create your new dimensioned sketch overtop of the image, just like Brain did initially. Then you can post your .dwg for everyone else.

Looks like scott just put a bunch of points along the picture and added a spline connecting the dots. You should be able to define a few arcs that are tangent to each other if you want an actual dimensioned drawing. Maybe the front arc, corner arc, side arc, make the part symmetric about the center, etc.

But yeah, for plywood, using a quickie spline would be more than adequate.

I actually drew a vector file in illustrator and exported the file as a dwg, then imported it into solidworks.

I have an ems in email if that works, forgot to upload the dwg last night.

I have CAD experience from my previous job but I don't have it on my computer at work, we have a design group that models all of our designs for us and I was trying to avoid "wasting" too much of their time for a personal project which is why I was hoping to just get a complete file to submit for a pricing quote. I will have to see if I can find a designer with a light work load/interest in cars that I can trade a ride in my car for some CAD work I guess.

Scott, I'll take whatever you have. It is a start at least

eMachineShop CAD Design File.

I think I was trying to use it on some site that would cut the ABS and ship it...this was YEARS ago. I just searched my mail and found it. I do have the DWG file at home, I just chose the wrong file it attach earlier here. I just need to remember to do it when I'm home.

although, you could do what Tim said, since it is to scale.

I will see if we can open an EMS file. And yeah I know I could, but "I" in this case means bugging a designer to do me a favor when I can just wait for the DWG file from you later. I am finally enjoying driving my car now, so I am not in a huge rush to start on a new project. Mostly just checking pricing and practicality of doing it this way for now.

If you remember to upload the DWG when you are home that would be great

Tim,

Care to upload the DWG file for the not boobies version? I can send that directly to the supplier to get a quote...so seriously no boobies because I don't have a way to open it myself to verify, I am trusting you...
