that was the moral of the recent article in Grassroots Motorsports magazine.
i am just worried the 275 will give me less traction than a (presumably)
warmer 245.

rather than putting the rubber bushings back, i am going to try these things
they call "shocks".  all the new adjustments on them are kind of
overwhelming.  =)

sorry this is so esoteric, i am going through autox withdrawal!
