[QUOTE="fabianyee, post: 183518, member: 6"] Try this... The calculation is for the E30 but your 5th gear ratio is 1:1.0, so just look at the speed for 4th gear. Calculation based on the following figures: Tyre : 205/60/15 (Stock E36 size) Rear diff / Final Drive : 3.45 [ATTACH]751[/ATTACH] So theorectically can get 100kmh at 3000rpm if using the 3.45 diff... if 3.15, can get 109kmh at 3000rpm... However, the speedometer always reading 5-10kmh higher... [/QUOTE]
