Hello, there! Not the most present poster, but thought this time was worth it.
Been struggling for this for ages, but good news for all you that think your legs are too long for the 145/146. This is for the LHD versions.
Will try to be quick.
Removed drivers seat and separated it from the rail tracks. Followed instructions from the «lowering driver's seat» mod.
Left side of the picture points to the front of the car. Notice that inside (top on picture) and outside (bottom) rails have different length.
Holes that fit the rail tracks on the chassis are exactly the same.
Holes circled in green are the original holes. Hole in blue is already present and will be used in this mod. The 3 holes in red are drilled new, with an 8 mm drill bit. I did it with a regular steal bit, but just 5 seconds a time and then dipped it into water to cool it. Holes in red and blue will be used to bolt the seat into the rail.
Each pair of holes is spaced 245 mm center to center. Use blue hole as reference and line the left side of rails with each other.
Will gain an extra 40 mm for your legs. Not much, but will feel huge. Paired with the «lower drivers seat» mod feels like a whole new car, like that 33 driving style
Hope some enjoy it!
