I agree about the setups Paul, I have used much the same on all variants.
Just a bit miffed that having done simulated half length race runs on x6 tyre and fuel using the BSCC on its Firestones I can now chuck all that out of the window and just guess what the NTK on its Dunlops might need. My conclusion was that my Elite and my BSCC were very close over race distance, assuming the Elite will go the distance on a tank full.
The Indy Ws 104 tyres on the BSCC are rated 7 on grip and medium on wear. I reckoned that I was good for 18 laps on them = a tank full of juice. This would have allowed me to minimise the amount of fuel needed to go in at the pit stop, saving time.
The CR65 970 Dunlops are rated 8 in grip, which is why the car appears to be a bit quicker. But they are rated as soft. I suspect that they will be shot before the fuel has run out. The alternative tyre is the CR65 184 but that is rated at 6 on grip and will, I suppose, be near the BSCC on Firestones. Just guessing you understand, with a possible whole hour of practice time left, max!
I am left wondering why we needed this late change.
In the end, I think that I am better off going for the Elite, although I hate the heap! That way, I do not run the risk of messing up the pit stop and as I have already done some practice with it, which strangely enough is still valid, I stand more chance of building on that rather than messing with the NTK. Despite it being the same on paper, I have always found it a little more "tail happy" than the BSCC.
