In 5-th gear with 3000 rpm my speedo showed ~ 110 km/h , thought that the speedo is optimistic so I checked it using the calculator. Turns out it's in the ballpark - 111.205 km/h / 69.1 miles atleast according to the calc. Looks like the 17" rims with 215/45 tires give quite a difference in speed compared to the stock ones - 205/55/15 or more likely my speedo was off with the sandard tires and now shows correctly. When I get a chance I'd like to verify it with the gps.
