    Default couple of tire questions

    1. what torque setting do you guys use on the PFM wheel nuts?
    2. what tire pressure do you usually start off with (cold) and what is your target for (warm)?

    I had this same question and someone answered it for me.
    Wheel nut torque: 104-108 lbs
    Stsrting tire pressure: 16 psi, check again after first run, it should be 20 psi.

    I think 104 is too low.

    The Torque spec sheet on this page (BTW everthing you need to know about running one of those cars seems to be there):

    http://starracecars.com/resources.html

    indicates 130 lbs-ft for the Wheel Nut similar to most of the other Van Diemen cars (we use 135 for the S2 and FC cars).

    Thank you, for some reason I had a mental block and didn't see the master bolt list but have it now
