Any extra maint required after racing?

[grover]

I know Porsches are already tuned for high performance, but I can't help but thinking the stress and strain of racing has got to be a little harder on the engine that typical spirited driving. Will 1 day a month of autocross racing have any significant impact on my car? Well, besides the tires, at least. Is standard 15k mile / 30k maint still all that's required, or are more frequent oil changes or inspections of anything recommended?

I have done track days and autocross in my Boxster and the only extra stuff I do is:

1) Inspect tires more frequently

2) Change brake fluid yearly (instead of every 2 years as Porsche recommends), or sooner if my pedal feels soft on track

3) Change oil more frequently (I believe Porsche now recommends every 15k or once a year). I change mine around 7k

4) Check brake pads for wear

I check other items before an event (air filter, coolant, suspension, etc.), but have not found that they need anything between the 15k/30k maintenance.
