Radial tire chatter

My car likes the back end very stiff, both rebound and compression.

Todd, the backend is already stiff with 250 lb springs but I do have the shocks set soft. Like I said, I started at 15lbs, dropped to 14 1/2 in the cool weather and was doing great. 1:452, 1:453, 1:452 60 fts. 2 weeks later it got hot and first I lowered the pressure to 14 then I raised it to 16. The last pass I eased it out trying to win the race and broke out by .005 so I didn't really get to try the highr pressure.
Thanks for the response.
