Alexander Sims was quickest in the second half-hour of GP3 free practice at Silverstone on Friday for Status Grand Prix.
Sims lapped the Silverstone Grand Prix circuit in 2m11.573s, almost a second clear of Lewis Williamson (MW Arden) and Daniel Morad (Carlin).
As in the morning's session, rain showers blighted the running. Williamson was fastest early on, quickly beaten by Sims, then Rio Haryanto and then Maxim Zimin, who then immediately spun off at Abbey and beached himself.
By the halfway point, morning pacesetter Adrian Quaife-Hobbs was on top, with Sims and then Williamson beating his time as the conditions improved. Despite more drizzle, Valtteri Bottas grabbed top spot for a few minutes, swapping the position with Haryanto.
Then Sims produced the quickest lap of the session, over a second faster than his rivals at the time and 0.93sec faster by the end. Williamson spun at Stowe as he tried to improve, as deteriorating weather conditions conspired against him.
With Tom Dillmann, Matias Laine and Zoel Amberg all going off and causing yellows, there were no further improvements.
