But to cut that much off the tires could reduce their life span on your car... so I normally trim the fronts down to 1.65 and rears to 1.72 - 1.75. Really many people dont even true the CRC Pro-Cut or the Jaco Prisms. They are already at race size.
in a big race though I would deffinitely keep them shorter and have more sets on hand.
Do you always try to run around a .08 - .10 split?
