Possable to adjust speedo???

[s1120]

Is it possable to adjust the speedo, to compasate for a slightly taller tire?? I have a 94 SL2 with a auto change.

To "compensate" for wrong tire sizes? Normally not.

Some older vehicles had different drive ratios that could be installed in mechanical drive speedos.

No. The Speedo is based of the differential and is a constant. Youll just have to note the difference in speedo value vs real value

OK, thanks.

Now didnt the SL1's have diferent overall gearing then the SL2's? Did they use a diferent drive gear? Other diferences????

The final drive ratio is the same for all s-series. However there are certain gears that are different including 5th.
SOHC = mp2 Man or mp6 Auto
DOHC = mp3 Man or mp7 Auto
