2023 Audi S5 — first HPDE in a stock street car

ProjectSeller897Community StarterSep 3, 20262023 Audi S5 SportbackBoston
I am doing my first beginner track day and do not care about lap records. Besides fresh brake fluid, enough pad, good tires and torque checks, what is truly necessary versus internet overkill?

Owner notes beat generic advice here. On the 2023 Audi S5 in Boston, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “first hpde in a stock street car,” that was the fork that mattered for me. Happy to compare notes if your setup is different. I'd rather look cautious in this thread than stuck later.

I'd keep this practical. Verify the cheap/easy branch on the 2023 Audi S5 before a big repair or a big spend. That's where I'd start. Verbal 'we'll take care of it' is not a plan. I've seen both outcomes, which is why I'd test instead of assume. Doing the boring step first on purpose.

That's a good start, but I wouldn't stop there. If it still isn't clear on the 2023 Audi S5, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. When does it actually happen? I'm keeping receipts and dates in one folder.

Write down what you already tried. A second data point from another 2023 Audi S5 owner helps more than a generic diagnosis. Then you'll know the next fork. If you share a photo of the worksheet, easier to sanity-check. Might be overthinking it, but I'd rather overthink than overspend.

Don't overfit one forum story to your car. If it still isn't clear on the 2023 Audi S5, a specialist hour can be cheaper than another round of parts. That's where I'd start. A shop burned me once by skipping that step. I'm keeping receipts and dates in one folder.

This is from a 2023 Audi S5 in Boston. Learned this the expensive way on a previous car. If the story changes I'll post the new data.

Thanks — that narrowed it. I'm going to try the simpler check on the 2023 Audi S5 first. I'd rather look cautious in this thread than stuck later.
