📓 Journals kitkat's Emira

[Steve Tillett]

Hello Steve, I karted with your padded seat over 20 years ago and it was one of the best seats in holding me in and comfort.
Still karting to this day at 54
So I know these will be awesome!
I will be getting it from Greg since he’s been so helpful and knowledgeable about everything. It will be the carbon with padding everywhere since I drive it to the track.
Are there options for red stitching and what color do you recommend for magma red?
This is the only combo will allow me to slide back and forth, correct?
And the angle of the chair can be adjusted as well, correct?
Do you recommend a 5 or 6 point seatbelt and which one?
Who’s roll cage or harness bar do you recommend?

We have standard thread colours but we can buy in any colour. It just cost to buy the reel of thread.
With stitch colours the shade does not have to be so close.
On the seatbelt question, the only thing I would strongly recommend is a crotch strap. Whether five or six point the most important thing is to stop the body travelling up the seat back should you go into the tyre wall backwards.
I would ask Greg on the roll bar question. I don't get involved in those.

I believe @GRP might be working on something

I will be wearing a HANS device so with that is a 5 or 6 point better?
Greg, what are you working on?

I don't think five or six point will affect a Hans device. The most important thing with a Hans is that the belts are properly positioned on the Hans and that in a crash the belts do not come loose. Flex in the seat or brackets can do that. Over long lengths of belts to badly positioned anchors can do that.

Even though I have owned my Emira for over two years and must have seen thousands of Emira images, sometimes I see a photo like this and think wow, it really is a fantastic looking car

3D Printed Rock Guards for the Emira

Just wanted to release a new design for the Emira. I had some TPU filament in 95A shore left over so I decided to design some rock / mud guards. This came about because after some fun on some back roads I noticed I have essentially destroyed the PPF behind the front wheels on the leading edge of the side sill, the rear fenders, and the PPF on the bottom of the rear bumper. These use mostly the stock hardware except for a couple optional extra locating holes for the front to use 3 push clips each instead of just the 2 factory ones.

How They Look

Printing Your Own

• See Attached Emira Rock Guards.zip for:
  • The STEP file modules for your own slicer.
  • A 3MF for a full 4 plate setup inside of your favorite slicer with all of the slicing settings.
• Tips on slicing:
  • Place them with the protruding nubs face up and turn on supports.
  • 7 wall loops and 15-25% rectilinear infill works fine for me.
• Tips on filament selection:
  • I printed these in 95A shore TPU, this works very well, 85A shore will be too soft.
  • 68D shore TPU will likely work too but maybe you may need to modify the model to be 1.5mm instead of 2mm thick, more on that later.

Can You Print Them For Me?

Nope, sorry you're on your own there, find one of your 3D printing buddies and have them help you out. While the cost is low for me, I really don't want to be in the 3DP business. Expect to spend < $5 in TPU and 12 hours printing a full set of 4 rock guards.

Can I Modify The Design

Absolutely! The following is the OnShape models, you can modify any parameters you want here as well modify the underlying sketches and features if you so desire. I've made the commonly modified parameters as variables.

OnShape: Lotus Emira Rock Guard CAD Model

You can modify the models simply by:

1. Create an OnShape free account.
2. Copy the CAD model into your own account.
3. Make the modifications you want, most people will just modify variables, the ones you're probably interested in are the "extension" variables. They drive how far the rock guard extends from your bodywork. Double click the variable to change and save it.
   
   
4. Right Click the parts and export them to STEP or STL file to your slicer.
5. Print your modified rock guards.
