South African double amputee Pistorius won the T44 100m in 11.23 seconds and the 200m in 22.01.
Briton Grey Thompson won the T53 400m and 100m, while fellow wheelchair racer Petitclerc took the T54 200m and 1500m.
Danny Greaves, David Weir and Kim Minett were among GB's other winners while Danny Crates won T46 800m silver.
An excited in the Arena watched on as Pistorius eased away from the pack of single amputee opponents to claim his first victory of the afternoon.
The South African finished second in the Athens 100m but made no mistake in Manchester, winning in emphatic style before earning his second gold of the afternoon in the 200m.
 Pistorius was in a class of his own |
Grey Thompson, who has 11 Paralympic golds, opened Britain's medal account by storming to victory in the 400m while London Marathon and Athens rival Francesca Porcellato had to settle for silver.
She then held off American Jessica Galli and Angie Ballard to win the 100m in 17.76.
The dame praised Manchester for organising the event.
"This weekend has proved that Great Britain can organise successful Paralympic events," she said.
Canadian Paralympic star Petitclerc, who won five golds in Athens, clocked 31.24 on her way to victory in the T54 200m before another comfortable win in the 1500m.
"But they were both very strong races and I'm very satisfied with the way I performed out there," said the Canadian.
Crates disappointment
Paralympic gold medallist Greaves broke his own world record to win the F44 discus with a throw of 55.53m, Ken Churchill also set a new world record of 48.40m in winning the F37 javelin.
But despite managing the furthest throw of the competition, Stephen Miller could only take silver in the combined F32/51 club competition under the scoring system for the event.
Elsewhere in the field events, Britain grabbed a one-two in the F40 shot with Minett winning gold with a 6.70m throw, and Sophie Hancock taking silver while Beverley Jones broke the British mark in the F38 shot with 10.94 to take silver.
Fellow Briton David Weir then bettered his bronze medal in Athens with a tight victory in the T54 200m.
But it was disappointment for Danny Crates, who was upset by Algerian Samir Nouioua in the T46 800m and had to settle for silver.
