I want to know what is the correct speedometer reading? Since the Vehicle Speed Sensor tells the Speedo what to display, does the dash show the speed, as it would be with the prelude tires, or the stock EG tires. cause we all know there is a diferance. I just want to know which one to buy tires for?? cause I can make up the differance with tire size...I would assume that I would need to calculate off the Prelude Tranny, and not the EG Speedometer, cause the speedo is just the display for the VSS. If any one has a good Answer for this, I would appreciate it, Thanks in advance... MzdaFrk
