Cross Drilled or Slotted Rotors??

[Joe Isuzu]

the point behind both is to get hot air away from the rotors and allow colder air in, the cooler that area is, the better your brakes will work and the less fade they will experience
imo both generally do the same thing but I have heard people claim the cross drilled rotors are more prone to cracking, I have cross drilled ones on my A4 and slotted on the VX,
personally, I don't believe any of us will be taking our VX on track anytime soon (I may be way off base on that but it seems like more people off-road them than track them) so I doubt you will have to worry about the potential problem with the cross drilled rotors,
the ones on my A4 have held up nicely but I only do 1-2 track events a year so that's hardly a lot of abuse, if you planned on going to a lot of track events I probably would stay away from the cross drilled ones but for me, it came down to price and availability, I don't think either will wear out anytime soon for my purposes

beware of cross drilled rotors if you plan to offroad, a few people have mentioned small pebbles can get wedged in the holes and take chunks out of your brake pads... although i guess in baltimore there isnt much offroading

I'll be your guinea pig! I live on a long, windy dirt road with lots 'o' lots of small pebbles and have had the R1 Concepts & PBR/AXXIS Ultimate Pads installed since the first week of July with no problems so far....let you guys know if I have any!

I have both cross-drilled and slotted rotors - no structural issues at all, but I don't recommend them because of the constant dust that scatters when you brake - the dust impregnates your wheels and can score the chrome or polished aluminum - in some cases when the dust gets wet it will pit your wheels - at minimum it's a pita to get off. The other issue is that the constant cutting action wears your pads down very quickly - something to consider.

What pads are you using ?

[johnnyapollo]

Stock Isuzu pads - someone posted a review of several and the stock pads won out as the best from the group tested on the VX.

The reason I asked is because I've always thought the stock pads did a great job of stopping me before impact, but I also like the fact that that they're nearly dust free compared to other cars I've owned. The increased dusting with drilled/slotted rotors is something I haven't heard of before.
Thanks.

the dust impregnates your wheels

Is that where 14" wheels come from?

He Cyrk, what caliper paint did u use and how is it holding up im painting mine soon as well.

I used G2 and now it is starting to peel...

I am running the R1 Concepts pads and drilled/slotted rotors. Quite honestly, I am not happy with my brake situation at the moment. I find that I have to stand on the brake pedal sometimes to get my VX stopped in a hurry. With my stock rotors and pads I could stop on a dime. However, my problem is, I don't know if it is the pads or the rotors that suck (or both). I am probably going to replace my R1 pads with some stock pads and see if it makes a difference. If not, then I will do away with the R1 rotors and try something else....

That said, Biju has had good results with his R1s, but I don't think he has R1 pads, and I know he also has better brake lines installed as well. Hopefully he will chime in...

I too had to stand on my brakes to stay stopped (and weren't enough to stop me on down slopes ) and went through the whole upgrade thing...
ss brake lines, bleed-bleed-bleeeeeeed...., discs, and finally new pads.

In the end I found it was the new pads (being thicker added to the thicker new discs). It wasn't anything with grip, I seemed to need more meat - the pistons appeared to be "reaching" too much with the worn pads and worn discs. Doesn't make too much sense when thinking in terms of brake line pressure... but now it grips as I step down and locks up about 75% of the way when stopped - as opposed to having to keep it to the floor to stay stopped.
