Mickey Bushell led a British medal and record charge at the US Paralympic National Track and Field Championships.
Bushell clocked the second fastest 100m time ever by a wheelchair athlete in any classification with 13.84 (+2.0m/s) in the men's T53 qualifiers.
The world silver medallist, 21, went on to take overall victory in the final in 14.76 into a slight headwind.
There were new world records for T34 wheelchair star Hannah Cockroft and F44 discus thrower Dan Greaves in Florida.
T34 world record holder and double world champion Cockroft set the standard early in the event with victory in the T33/34/51/52 200m in 32.01 (+1.7m/s), reducing her previous global best by over a second.
She also improved her 400m world mark with 1:02.52.
World champion and former Paralympic gold medallist Greaves exceeded his own F44 discus world record with a best distance of 59.85m for victory ahead of American Jeremy Campbell.
"It's outrageous, it's so [to 60m] close it's unbelievable," said Greaves, winner of the recent Paralympic World Cup in a then-world record of 59.27m.
