Oli Basey-Fisher encountered a frustrating visit to Silverstone Grand Prix Circuit over the weekend, 31st May/1st June, where a potential GT4 Class podium finish in the fourth round of the Avon Tyres British GT Championship went begging due to oil pump failure midway through the three-hour race.Up until that point, the Academy Motorsport-run Ginetta G55 GT4 the Great Finborough driver shares with Matt Nicoll-Jones was running like clockwork and had battled through into podium contention from sixth on the class grid.Despite the disappointment, Oli remains incredibly positive for the season going forward with the competitiveness of the car having improved significantly since the start of his maiden GT season back in April.“It’s frustrating for something like an oil pump to cost us a likely podium, but the car was very strong and competitive this weekend – the team has made massive strides with it”, said the 18-year-old from Suffolk, “This weekend we really thought the Aston Martins would be leagues ahead with the top speed, but we were pleasantly surprised the Ginetta was really strong compared to them.”Qualifying went well in terms of pace with the Century Logistics and DCB (Kent) Ltd-liveried car setting the third fastest time in GT4. An unfortunate penalty for Nicoll-Jones, though, meant the team would start the longest race of the season from sixth position.Oli took the opening stint and although getting away cleanly, contact ahead in the GT3 Class on the run out of Copse resulted in a significant delay although, luckily, no damage. Having slipped to eighth in GT4, the British GT rookie set about climbing back up the order but more frustration followed with a debateable drive-through penalty.After serving the penalty, Oli returned to the track before handing the car over to Nicoll-Jones during the first of the mandatory driver change pit-stops on lap 14 and the latter made great progress to pull the team into podium contention before the oil pump failed at the midway point.“We showed good pace in qualifying and should have been P3 but we got penalised as they decided Matt [Nicoll-Jones] hadn’t done enough laps – we had to do three each”, explained Oli, “Technically, he did do three but at the end of the last one he came into the pits so we had to start P6 in the end.“The start wasn’t great for me, unfortunately, as a GT3 Ferrari ended up facing me in the middle of the track on the run to Maggotts and Becketts. Everyone was really close initially, then I had a tussle with a Lotus which resulted in a drive-through penalty which we didn’t think was warranted to be honest”Oli added: “The pit-stop worked perfectly, though, and Matt had a great stint. It was all going well and at that point we were the fastest car in GT4. Just near the end of his stint, though, the oil pump failed and that was it unfortunately. It’s so frustrating as we could have had a podium.”Oli now has just three weeks to wait until his first British GT outing on home soil at Snetterton 300 Circuit. Rounds five and six of the season will take place over the weekend 21st/22nd June.
