Any recommendations on fluid you guys use? No track days. Spirited driving on weekends only.

Changed my brake fluid in 2020 (around 15,000 miles ago). Is it too early to change it now?

 

Unless you're going for a boutique brand don't sweat it and buy whatever has a reasonably high boiling point. 3 years is a good interval, 4 and the fluid starts to turn.

 

I used Prestone DOT3/4. Any reputable brand will be fine.

 

The manual calls for DOT4. So you can use any decent brand at the auto parts store, just make sure you flush/replace it regularly. Maintenance schedule has it at every 30k miles. It wouldn't hurt to change it now just based on time since the last service.

Since I do track mine, I use Motul RBF600 every year or two (depending on how many miles the car was driven) with a top-off bleed before events.
