Hey guys I put Wheels on my car and they are 20 in the back and 19 in the front, I think it messed up my speedometer but I'm not sure...I do know that at 2,500 rpm's in 6th gear that it says I'm going exactly 69. if anyone with a stock crossfire could let me know what the speedometer says on their car at the same rpm and same gear that would be great. Thanks.
