Brake Discs are warped. Should I change to Rotoras or Brembo?
I just want value-price suggestions. I am looking at rotoras (slotted) for 250$ in total and brembo (slotted/drilled) for 250$.
What should I take?

How many miles on the car? The dealership might service or replace your rotors. It's worth a try.
If not, I would go with Rotoras, unless you are getting the real Brembos. Most that are going for cheap are Brembo blanks, which are later drilled and/or slotted. They tend to crack. I've heard good things about the Rotoras, and you can contact Scott about those. His AIM screen name is TL Type S on 19z. He sells them, along with other stuff. I've bought from him in the past and I've had excellent service.
Good luck.

You got front and rear rotors, and all the pads for $230? Shipped?

I'm assuming you are talking about just the fronts right?

They will help with the cooling of the front brakes, i.e. prevent warping.

Rotora slotted is the way to go, hopefully one say when I ever find that money I buried in the back yard I can start modding again, and get some.

No, the person spouting that drivel needs to read abit more and stop making black-and-white conclusions about a subject that is rather complicated.
Short answer:
Some drilled rotors are terrible.
Some drilled rotors are ok.
The slots help -- PERIOD.
I hope your not reading stuff from the same guy that would probably have everyone driving around with SOLID rotors as the metal will store more heat...

Please! If you have an opinion, that's fine. But just because some folks associated drilling with performance, doesn't mean high-end companies put holes in rotors to impress.
Some use the holes to reduce unsprung weight and to lower rotational inertia.
Others cast the holes in the disks.
Others use special metalurgy to reduce stress and pay attention to careful design issues.

SRP Drilled Performance Rotors feature a specially engineered directional cross drill and face slot pattern that improve brake response and pad performance throughout the entire range of light to heavy braking. The venting and cleaning action of the holes and slots will reduce pad glaze and disperse gasses and heat generated during the pad to rotor interface. The holes and slots also inhibit irregular pad compound build-up on the rotor faces resulting in smoother engagement and improved pedal response in all conditions. The material removed also contributes to lower rotating and unsprung suspension weight. Along with the excellent performance characteristics of this rotor design, each rotor is treated with a silver zinc wash to inhibit corrosion on all areas of the rotor not swept clean by the brake pads. The high tech design, classic style, and aesthetic appeal of the SRP series are the perfect finishing touches to any wheel and tire detail. SRP rotors are available in all popular sizes used in Wilwood's Pro Series and Big Brake conversion kits. Kits in these categories designated with the drilled rotor option get the SRP as standard equipment.

Disc Choice
AP Racing Formula Brake Kits come supplied with large diameter discs. The ventilated discs have either 24, 30 or 48 cooling vanes depending on the application, to draw air through the centre of the discs. They are handed left and right, and are cross drilled or grooved, again, depending on the application, to allow gasses that build up on the surface to escape. Where cross drilling is used it is more restrained than on the face of our full race discs, as pad longevity is more important on a road car than weight saving. The discs are wider and of a larger diameter than standard. The extra material controls heat build up and the larger diameter means that the caliper can be mounted further away from the centre increasing the leverage effect, which increases braking torque while decreasing effort required on the pedal.
Grooved Discs : G4, G8, Grooves improve 'cleaning' of the pad surfaces and result in a more consistent brake performance. Grooved discs have a longer life than cross-drilled discs.
Radius Drilled Discs : RD, Radius Cross-Drilled discs offer improved 'bite' and 'feel', but are less resistant to cracking than grooved or plain discs.
I could go on and on with more examples. This lame argument has really gone on long enough. Some people are into looks and buy stuff -- like huge wings -- that won't help their underpowered cars ever reach speeds high enough to enhance their grip; that doesn't mean that wings are only for show. This same argument has been tossed around on newgroups and forums for ages. There are many examples of poorly drilled rotors. Some of these sad examples even had holes drilled through the vanes. The list goes on and on. Just because some nitwits don't have a clue about their "doings", doesn't mean that everyone who uses some technology with possible "downsides" are going to produce a defective or inferior product. IOW, not all rotors with cross drilling are for looks. Depending on the brake company, x-drilling is useless in all conditions, or x-drilling can be used to help cooling and weight...

people any rotors going to warp. the reason for the rotors warping is because you guys are washing your cars when the rotors are hot. make the car cool down first before you wash it.

You are absolutely right. The ONLY reason rotors ever warp is because we wash our cars when the rotors are still hot from driving. Geez, that should have been put in the TSB about our front rotors warping.

the dealer will also bend u over for 15, 30, 50K service and tell you the trannies are fixed....don't believe the hype man...its just common sense to know about spraying cold water on hot rotors. The dealer will tell you anything to avoid fixing warranty shit.

Yea- one time, at band camp, I drove my car right into my driveway from the freeway at 112 mph and started washing my car. Naturally the first place I sprayed was my rotors.
