Hey Everyone,

I drive a 2013 335i (n55) (80k) I was wondering if i should do any preventative maintenance before i go stage 2+.(NOT asking what parts i need to go stage 2)
I have done just about all the recommended maintenance up to this point. Should i be flushing all my fluids if it hasn't been done in a while? (trans, diff, brake)

Thanks!

At 80k miles you would be well served to drain and fill all the drive line fluids. Brake fluid is also not a bad idea if it hasn't been done in the last couple of years since you'll be leaning on it a bit harder going forward. I'm not sure if you are Auto or MT, but the ZF8 has a very specific procedure and to replace the filter you need to buy a whole new pan. FCP Euro has the whole kit for $275 or so. Diff is a very simple drain and fill procedure, no new parts needed unless you want to replace the drain plug.
