Problems with AP discs warping?
It'll be nothing to fo with AP at all. Have had no problems with mine or my brother's AP setups on our cossies ever.
I have never heard of one single cossie owner warping AP discs on a regular basis, and we all use them on track.
Believe me, no-one uses brakes more aggresively than Mike, and if he's had no problems, you'll be fine.
PMSL - can't believe these guys aren't rating AP and Brembo - the two biggest and best aftermarket/race brake manufacturers in the world.
