Better gear ratio for W123 Diesel – What axle would fit ??
15" wheels should help the MPG on my 300TD I mounted 15" steel rims with 205/75 tires. The RPM dropped by 10% so I hope I get some better than 20MPG. The ride is super nice on the highway and the tires are stiff enough for stability.
1. What differential could I use for better gear ratio??
2. In what other models can I find that differential ?
