More cars than I've got space to park!
Apologies for the late reply, it's been one of those days...

So, with your tyre size, in 4th gear (1:1) here are a range of diff ratios with RPM @ 60km/h, 80km/h & 100km/h:

Code:
Tyre Size = 235/60R14
Tyre Revolutions = 499 per km
Gear Ratio = 1.00:1
Diff Ratio 2.60:1 = 1297 RPM @ 60km/h
Diff Ratio 2.78:1 = 1387 RPM @ 60km/h
Diff Ratio 3.08:1 = 1537 RPM @ 60km/h
Diff Ratio 3.36:1 = 1677 RPM @ 60km/h
Diff Ratio 3.55:1 = 1771 RPM @ 60km/h
Diff Ratio 3.70:1 = 1846 RPM @ 60km/h
Diff Ratio 3.90:1 = 1946 RPM @ 60km/h
Diff Ratio 4.44:1 = 2216 RPM @ 60km/h

Code:
Tyre Size = 235/60R14
Tyre Revolutions = 499 per km
Gear Ratio = 1.00:1
Diff Ratio 2.60:1 = 1730 RPM @ 80km/h
Diff Ratio 2.78:1 = 1850 RPM @ 80km/h
Diff Ratio 3.08:1 = 2049 RPM @ 80km/h
Diff Ratio 3.36:1 = 2236 RPM @ 80km/h
Diff Ratio 3.55:1 = 2362 RPM @ 80km/h
Diff Ratio 3.70:1 = 2462 RPM @ 80km/h
Diff Ratio 3.90:1 = 2595 RPM @ 80km/h
Diff Ratio 4.44:1 = 2954 RPM @ 80km/h

Code:
Tyre Size = 235/60R14
Tyre Revolutions = 499 per km
Gear Ratio = 1.00:1
Diff Ratio 2.60:1 = 2162 RPM @ 100km/h
Diff Ratio 2.78:1 = 2312 RPM @ 100km/h
Diff Ratio 3.08:1 = 2562 RPM @ 100km/h
Diff Ratio 3.36:1 = 2794 RPM @ 100km/h
Diff Ratio 3.55:1 = 2952 RPM @ 100km/h
Diff Ratio 3.70:1 = 3077 RPM @ 100km/h
Diff Ratio 3.90:1 = 3243 RPM @ 100km/h
Diff Ratio 4.44:1 = 3693 RPM @ 100km/h

And some pretty pictures showing the speeds in each gear at a shiftpoint of 5000rpm for the diff ratios of 3.08:1, 3.36:1, 3.55:1 & 4.44:1:
