I'm due for my 30k service but looking at what needs to be done I'm curious if anyone else has gone a-la-carte. Let me explain.

Among other things the 30k is a tire rotation, oil change, brake flush, tranny & diff fluid change, PCV, and I believe air filter. Well, I'm modded and like many I've done some of these myself already. For example:

Tire rotation: my track tires on on there now, really don't need to be rotated.
Oil Change: OK, needs it, go ahead
Brake Flush: I bled mine about 1.5k ago and changed the fluid for DOT4 while prepping for a track day. Really doesn't need a change.
Tranny/Diff: Swapped for motul about 20k ago - likely needs a change but rather not go back to stock fluid.
Air Filter Change: I have a drop in K&N that I cleaned maybe 500 miles ago. Don't want/need another OEM filter

Question is can I get "credit" on the service record for doing the 30K service and ask them to simply not do some of it? Deal gave me a price of around $600 for the whole thing which seems crazy considering I might not need/want them to do it all.

Thoughts? Advice? Flames?
