I have a 2001 Mustang GT, the tires have been changed and I would like to know what I have to do to recalibrate it to make sure that I amtravelling at the correct speed, and where canI obtain such a calibration device? And also I have to install wheel spacers and I understand that I have to install a Panyard bar on the car, if so where on the car do I install it, and is it absolutely necessary?

Thanks
Soca

 

you need a handheld tuner to recalibrate the spedo and you can get them at pretty much any mustang performace sites/shops. As for the panhard bar i have no idea maybe someone with a new edge will let you know

 

Go to this website and check the number of rotations of the stock tires against the number for your new tire size.

Tha bar you are talking about is (I think) a "panhard" bar.
Steeda and Maximum Motorsport make a couple of different designs.
