Hey Leon awesome video and very very interesting compared to mine! I didn't actually record any videos the last time out because i had a new tune in the car and between sessions we were touching up the tune getting rid of some gremlins etc and had no time to mount the camera.. But i have lots of other videos at different tracks so feel free to check em out, including one Winton test/tune day i did just after Sandown https://www.youtube.com/channel/UCtrsHx ... 9LzHn77KAA
Looking at your GoPro video i can see a few areas of difference already.
1) Your top speed is at least 12 km/h faster than me on main straight, i am only getting up to 200km/h before braking hard at 100m mark.
2) I am braking later than you on main straight and definitely on back straight and still i am slower which is quite surprising!!
3) Other than those 2 obvious areas you probably have better drive out of corners than mine being a 2.5litre so that helps you on the straights too.
In all slower corners i use 3rd gear, not sure if you do the same. The gear ratios in my car has a very short 2nd gear so i have no choice really.
I have a feeling the difference is largely down to the better drive out of the corners and top speed, Sandown being a horsepower track after all. But i am still very impressed by your laptime considering i am on r compound tyres. How much camber do you run?
