I have some cross drilled break rotors at the moment which were recently machined. They told me they were good for about another 8-10k but one of them has developed a 1cm crack on the outer edge. How threatening is this? How much longer should I rely on them or do they need to go ASAP?<p>The next part to my question is should I go ahead and buy another set of cross-drilled or are the powerslot rotors a better option? Should I get them from IPD or are there some other distributers that would should be considered? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">

I'm no expert but I wouldn't feel comfortable knowing a rotor has a crack in it given the temperature and pressure it deals with. Also, cracks tend to get bigger.<p>I love my X-drilled Zimmerman rotors but many people are fans of the slotted b/c they're less fragile.<br>IPD has the powerslots I think? eEuroparts has the zimmerman X-drilled rotors. Eurosport Tuning also sells slotted and drilled rotors as another option.

Re: Break rotors: cross-drilled vs. powerslot? (echristodo)

I had the powerslots on my T5 from ipd. They run specials from time to time. I liked the finish on the rotor hats that prevented corrosion to some extent. I would highly recommend them (both powerslot and ipd).

As an aside, would it be possible to through some S60r Calipers on a set of powerslot rotors on my S70?

I vote stock and paint the hats so they don't rust. Holes and slots are bling.

I'm really not looking to get into an argument (honest) but there is some science behind why drilled and/or slotted rotors are better. They let the gas escape so a layer doesn't build up between pad and rotor. It reduces break fade and enables you to stop faster. I've noticed a difference personally.
