I thought I would share my trackday experience at Silverstone GP circuit last Sunday in my CAV GT40. This was only my second trackday and so was a little apprehensive to begin with. There were no slow cars on the day, the field comprised of Porsche GT3's, TVR's,Radicals and fast Caterhams ,Ferrari 430,there was even a Porsche GT2. Needless to say that I was slow to begin with as I had only done Silverstone on my Xbox 360 before!.
After a few laps and my son acting as a co-driver I soon got the hang of the circuit and I was able to keep up with the Porsches, I even passed a lovely black Corvette Z06. I was really pleased with the Avon cr6zz tyres I had put on the car recently ;provided enormous grip and confidence. Driving a GT40 fast is a physical experience especially around slow corners when the steering feels quite heavy and strong arms are required, power steering would help.
It wasn't all plain sailing though, the day was marred by brake fluid boiling and giving a very soft pedal and a loss of full braking. In the afternoon I was having to come in after every two or three laps to cool down the brakes. I had not changed the year old DOT 4 brake fluid before the trackday.
I have now decided to put in Castrol SRF fluid, which is very expensive £40/litre!. Any advice on how to drain the old and put in the new fluid. Do I simply flush the system with the new fluid?.
