speedometer calibration
I'm replacing my 15 inch wheels with 245/35/20s (all four) on my '92 ls4. With tanabe/kyb set up. I'm concerned about my speedometer being off. Any recommendations, if it needs to be adjusted, on where to go to get it calibrated.

Strip the cluster, take the cover plastic out, reach the needles and you will find a balancing screw on the inner end of the gauge.
All you will need is a philips (star) screwdriver...
That's how I did mine...

that doesnt really calibrate the speedo...just makes it read a set num. of mph less than whatever, which wont be accurate since the wheel/tire is a percentage off, so the absolute value of the inaccuracy is directly related to the actual speed you're going...
ie-low speed=small absolute inaccuracy, high speed=higher absolute inaccuracy.

Hm, correct in technical terms, but that is the only way I managed to "calibrate" my speedo as it was around 7-10 Km/h off...
Now it is 1-3 Km/h off (didn't have time to go into perfection )...
