    This one is a different angle in a 2017 WRX sti, surprisingly the best time I got with this was 0.013 seconds slower than the Redline. (Shows how far the VF2 has come in handling dynamics as the WRX 10 years earlier would run rings around any Commodore.)

    In terms of upgrades.

    Brake pads are a must.

    Brake fluid to high temp is a must. (Some people do every track day I change every 12 months) factory is 24 months.

    Tyres - street tyres are fine for casuals as you will just hit their limit sooner but unless you are serious and will invest in some rims and semi slicks which is costly for a few days a year. Tyre pressure is important, I run close to 30psi when cold as they heat up considerably and increase to high 30s. You will wear your tyres a fair bit but I still got 30k km out of the rear set with 3 track days.

    Engine oil - change sooner, some people change every track day, I just change it every 7.5kms with a good quality oil. Had analysed and wasn’t too bad.

    Gearbox and diff fluids - half the manufacturer recommended intervals.

    Other than that just check your car for any leaks or unusual issues like bushes etc as there is plenty of force on the car.

    Finally got back to the track again after the cam and tune.



    Managed a 1:10 which I was happy with. Microphone doesn’t pick up a lot of the cam as it’s too low frequency.

    Any idea what your fluid temps are doing during these track day conditions?

    Coolant was about 90-100c and oil was max 125-130c.

    I’d like oil to be less so looking into a setrab oil cooler but they are pricey at $860 from harrop. Also also running Penrite 10 tenths which helps as it doesn’t shear with the higher temps.

    On the other hand I will eventually need to have the calipers powder coated as the heat has got to them as they are maroon now not red haha.
