Transmission, Diff, Brake Oil and Fluid ! (Track Use) + Updates

[Yellow350]

View attachment 113841 Hello,

Thanks for the support in previous posts,

I attend track day every 2 weeks, it's my 5th Track day, i did change my engine oil, never changed my Brake Fluid, Trans and Diff Oil?

When should i change them? Any additional recommendations?

UPDATES: I will be installing Toyo R888R tires for my next sessions, i hope to get at least 1.5 Sec Gap,

With respect to your location and the heat you see I would absolutely use a high quality brake fluid such as Castrol SRF.

And my God are the export side view mirrors ever bulbous.

Also, your front splitter (in the middle) is not seated all the way in the tabs, I would get that corrected too before your next track event.

The weather in winter is pretty cold here, we only have track days in the winter

The weather in Qatar is Extremely Hot (around 125F), cold days are only in winter, that's why they open the track every 2 weeks so people can enjoy before summer comes in again :first:

Out of curiosity...how cold are "cold days" in Qatar when you are tracking the car?

The Avarage is 57F during winter, it gets colder in some days

Ideally you should bleed the brakes after each track event. If you're not hard on the brakes, you can stretch it out to every 3 track days or so. I would definitely recommend Castrol SRF.

Also, please keep us posted on the R888R tires. I'd love to know how much faster those are than the Cup 2's. They do weigh a bit more, but it should be a faster compound.

Transmission and rear axle fluid swap would be recommended just because of the heat you potentially run in. Plus the transmission comes with ATF from the factory which is not ideal in a manual. I would also recommend a swap to 75W-140 in the rear axle. This KIT is the best value

As far as brake fluid, SRF is the best but depending on your driving the OE fluid, flushed every few months is still really good.

Let us know if you want to upgrade to a more track oriented brake pad when the old ones wear out ;)
