They tires are 215-40-zr18.. would that set the spedo off? I wanted to see today so i hit it, and my spedo made it up to about 32,33,34 mph and it redlined. Usually if I shift at redline, the spedo is at like 35 or a little above. Is it just me imagining, or is it off? 99 CSVT - green : SOLD 99 CSVT - Green : SOLD Supercharged Mustang - fire ...

The stock speedo was reading a little fast to begin with the stock rim and tire combo. Stan 98.5 SVT#6092 of 6535 B/MNB Born on date 5/22/98 Y2K Suzuki GSXR 750 Y/B with 140.6HP
