Avid Track Day peoples.... slotted vs crossdrilled....
There are reports on the interwebs that cross drilled rotors might crack with lots of track use. I was wondering if you have seen this on the 986s boxsters...
The 986s has thicker spec and larger rotors than the 986 used normally (I don't know if spec boxster uses the s rotors or not...

I tracked my car on a shorter 'technical track' (lots of 2nd,3rd, and some 4th gear) for about 10 hrs last year (1 daytime event, 4-5 evening events)...

I need new street pads and rotors soon. I have Hawk noisy track oriented pads that I swap out for trackdays. I also have track rubber this year to use.
I plan to go to 2 daytime events with 2-3hrs tracktime/day and probably 3-4 evening events with 1-2hrs of tracktime per evening

I like the look of the cross drilled rotors through my street wheels, but wonder if I should switch to slotted rotors for both track and everyday use.

I found a company up here in Canada that takes rotor blanks (read - probably from China) and then slots or crossdrills them... Price is very good... about $635 for 4 rotors and pads...

First trackday is 2 weeks away... need to order soon.
