As per my copy of the F.6 pilots notes, normal G-limits were +6G to -3G, this had it’s own set of variables depending on which missiles were fitted, ventral tank empty/full and relative speed of the aircraft, essentially though these were the limits the pilots worked to in normal operational flight.

With the overwing tanks fitted the G-limits were reduced accordingly….

Fuel in overwing tanks 3.5G (3G above 475 knots)
Overwing tanks empty 4G (3.5G above 475 knots)
With single missile 2G

As for maximum airspeed the in service limit was 2.0M/650 knots, whichever is first attained but with overwing tanks was dramatically reduced to just 0.98M/525 knots.
