Stillen Rotors (does installation require any other mods?)
STILLEN Sport Rotors are an exact size as OEM rotors,for my05 wrx now my question is if i pit these rotors on my car will i have to change any breake lines or anything like that?:boink:
Wrong forum. If they're cross drilled I'd stay away from them. If you do want them and they will fit all you need is the rotors. SS lines and some RBF fluid would be a nice addition.

You might want to change out the front pads for something more aggressive than the OEM pads. I'm using Hawk HPS right now and they offer better response than the factory pads while dusting less than the Axxis Ultimate pads I've used before.
Follow pad manufacturer instructions for bedding in new pads.
Factory rotor removal (some aftermarket rotors do not have threaded holes for rotor removal from the hub flange).

The Brembo web site makes no mention of avoiding cross-drilled brake rotors. Brembo market kits with either slotted or cross-drilled rotors.
StopTech also markets big brake kits and replacement rotors in either cross-drilled or slotted design, but says this in one of their FAQ papers:
The most common recommendation is to stay away from drilled rotors for track use but they are okay for normal or spirited street driving where the rotors will not see sustained high temperatures.
I've seen photos of cracks emanating from the cross-drilled holes, but have never seen cracks on the cross-drilled rotors on street cars in person.

The main advantages of drilled and slotted discs are the same: increased brake "bite", and a continuous refreshing of the brake pad surface. Drilled discs have the additional advantage of being lighter and running cooler. However, there are certain pad materials that should not be used with a drilled disc.
Are discs with cast-in-place holes better than cross-drilled discs?
Brembo has extensively studied and tested cross-drilling versus casting the holes in place and found no significant effect on performance or durability.

For many years most racing rotors were drilled. There were two reasons - the holes gave the "fireband" boundary layer of gasses and particulate matter someplace to go and the edges of the holes gave the pad a better "bite".
Unfortunately the drilled holes also reduced the thermal capacity of the discs and served as very effective "stress raisers" significantly decreasing disc life. Improvements in friction materials have pretty much made the drilled rotor a thing of the past in racing. Most racing rotors currently feature a series of tangential slots or channels that serve the same purpose without the attendant disadvantages.

I track my car and like Wingless Wonder said they are prone to cracking when heated too much. Many people don't think they will track their car much until they participate in a track day. Track days are addicting and that is one of the reasons I wouldn't recommend cross drilled rotors.
I ended up going with a set of Brembo blanks and they've held up great.
