Made out of ABS White high temperature resistant 3d printed parts Every kit includes the three gears (vdo). The factory gears get soft over time (imagine how a stale Oreo cookie would feel when broken in half, thats what the gears in your current broken gauge feels like). On these euro versions (kmh) there are a couple different options for the third gear count. Please check the number of teeth on your third gear to confirm you get the right version. If you do not we will send you the default (and most common) euro tooth count. These gears are quality made with better then oem material with a quality fit and finish. These gears will outlive your car! Installation instructions can be found here: VDO e30 installation instructions. CHECK IF YOUR CAR HAS VDO OR MOTOMETER UNIT BEFORE BUYING! Make sure your are buy the correct unit for your car as well (MPH or KPH). You must check for these two things before buying. These cars came with both versions for each country!
