Hey guys!
Due to popular demand, here are instructions on how to make your own Audi TT 8N 5- and 6-speed Open Metal Shifter! It’s a lot of work, but you can’t go wrong with these very detailed instructions. (thanks to metal-designer in Germany for sharing his pictures along with his autocad files!)

In this guide we explain how you can build the Audi TT 8N shifter, step by step. We have attached this all the necessary information, such as the construction drawings of the Laser and milled parts as well as the suppliers where you can buy the necessary parts.
Tools needed
1 Glue gun
2 Allen key set for different sizes
3 Wood drill (diameter: 5mm)
4 Screwdriver (slotted and cross)
5 Cordless Screwdriver
6 Scissors
– Needle and thread to sew the switching Sacks (the same color leather)
Material needed
1 Leatherette (430x175mm)
2 Stainless steel design – Shift Gate (Material 1.4301 polished 3.0mm)
3 Spacer
4 Cable ties PVC Length: 200mm
5 M4x50 cylinder head IMBUS 8pcs
6 Aluminum ball (d = 50mm polished, threaded blind 12 × 1.5 – 20mm)
7 Panel for shift stick (inner diameter: 12.5mm, length 95mm, thickness: 0.5mm)
Time to get going, let’s start the project!
Ordering the laser cut stainless steel design – Shift Gate
There are two possible variants: Variant 5-speed or 6-speed . We have the AutoCAD drawings for both.
DXF drawing of the 5-speed version: Download (zip file)
DXF drawing of the 6-speed version: Download (zip file)
Contact a machine shop with the following information:
Drawing: download the right dxf file above
Material: 1.4301 stainless steel
Material thickness: 3.0 mm
Length x Width: 139.7 x 139.7 mm
Quantity: 1 piece
Ordering the Spacer ring
This is very similar to the stainless steel Shift Gate. You need the attached file and a supplier that will create the part for you (not necessarily a machine shop this time).
DXF drawing of spacer ring: Download (zip file)
Contact a machine shop with the following information:
Drawing: download dxf file above
Material: MDF
Thickness: 25.0 mm
length x width: 140.5 x 140.5 mm
Quantity: 1 piece
Ordering the aluminum ball (optional)
Now comes our third order – optional, because you could also use the original shift knob.
For the aluminum ball, we do not need any drawing. Simply source a supplier that can get you:
Aluminium ball polished
Diameter: 50.0 mm
blind holes: 12 x 1,5 – depth: 30.0 mm
Quantity: 1 piece
Ordering the Shift Stick (optional)
The shift stick is the short stainless steel tube that is pulled over the original shift stick. It isn’t necessary for this job, however it is recommended since it looks better.
Again, no need for specific files. Simply source:
Material: Stainless steel Pipe
Outside diameter: 13.5 mm
Inner diameter: 12.5 mm
Wall thickness: 0.5 mm
Length: 95.0 mm
Quantity: 1 piece
Preparation of the spacer ring incl. Leather trim
It is possible that after the production of Spacer ring, the 8 holes may not be complete (go from side to side) – if not, we must re-drill them. For this we take our cordless screwdriver and drill with a diameter of 5mm and drill the holes at the end (see picture red). We also need one extra hole using the same drill but just about 5-6 mm deep, located in the middle of two complete holes (see picture green). These will be needed later during installation, as most TT’s have a little nipple on the threaded plate. We’re done for now with the spacer ring – now comes the leather trim.
Preparation of the leather trim
We now cut our piece of leather (leatherette) to the exact dimensions of 430 x 175 mm (please pay attention to right angle). Now we have a rectangle with the dimensions 430 x 175 mm available.
We turn this around (ie with the “leather side on the table.” So now we have the blank (the contour that we will cut later with scissors) of leather blank canvas (see image).
Draw the lines on the blank canvas for future cutting. Make sure you take your time to do it properly. Now you’re ready to cut the canvas using your scissors. For this we have attached a small photo gallery:
Now that we have cut the leather perfectly, we can devote ourselves to the sewing. Here we must be careful a little bit so that we sew everything in the correct order. Therefore, we have created you a small list – please adhere strictly to this order:
1. The 3 oblique inner seams
2. The upper tabs
3. The outer seam
Note: We sew the shift boot to the left and then invert it at the end in order to right – thus we have on the visible side a nice seam. As with a T-shirt which is washed on the left and then turns back to the guards on the right.
Follow the pictures and sew only along the red lines shown above, then nothing can go wrong:
Connection of leather trim with the spacer ring
Now is the time to connect the leather trim with the spacer ring. For this purpose you need the glue gun to drop hot glue on the inside of the ring (Drop glue on just 1/4 of the ring). Immediately fold the excess leather inside the ring (see pictures below) and hold the leather inside the ring for a few seconds until the glue has solidified. (use gloves to protect your hand from hot glue)
This process is repeated a total of 4 times. Thereafter, the spacer ring should be wrapped entirely in the leather.
Now revert the head of the leather trim (the narrow end) through the ring and pull the cable tie in the tabs at the top of the leather covering. This cable tie is later used to securely connect the shift boot with the shift stick. Please snap a few teeth the cable tie to ensure that there remains sufficient clearance for assembly.
The final step for the spacer ring is to drill holes into the leather for the mounting screws. For this, use a small pin screwdriver. You have a total of 9 holes to drill. Do not forget that 8 are complete holes so that the screws can pass through the ring. The spacer ring is now completely done!
Now should you have the following parts:
It’s very easy to install now.
Well that completes the translation guys. Hope you try it and let me know how it went! Not an easy task but hey, it’s worth at least $200 🙂
I’d like to get your comments, so fire-up!
