Hi Sam,
1.33xx is considered fast around here
so theres not alot wrong with your driving
watching the replay, you tend to drift too far right when braking for Turn1, if you stay to the left and take a similar line like you take through T3, you could get on the gas sooner, there you could gain 10/100 sec before the 1st split and carry the extra speed down the straight into the 2nd sector, you could also try trailbraking (possibly requiring some changes to the set) and this might also earn you a few 10ths
Most of my XFG sets use around 20-30 PSI the lower your tyre pressures make the car feel like it has more grip but tyres will heat up faster and produce slower top speeds, I would have a play with the front and rear camber settings, feel the changes and fine tune with the ARB's.
How much fuel do you use? if your gonna do all that tyre warming nonsence
just fill to 5% or so, the lighter the better.
What view are you using? if custom or wheels view try swapping the driver to RHD for clockwise tracks, it makes a small difference to cornering and tyre wear
Change your cars colour to
RED they are always the fastest cars
Practise practise and practise
