Rotor recommendation for stock calipers

[Racer Doc]

I have a stage 4 or 5 2001.5 S4 in need of new rotors, I am looking for advise on what type to go with, also interested in advise on a bigger brake setup.

Thanks

So your S4 is running a jet engine? What is stage 4 or 5?

[ny02s4]

Zimmerman cross drilled or a nice two-piece rotor.

Stg 4 or Stg 5...WTF?

[Mike@PureMS]

Stock calipers can only use stock rotor size. 321x30mm

Zimmerman FTW

ecs zimmerman rotors drilled n slotted 200$

[exorcet]

based on the information provided i would definitely upgrade to a stage 4 or 5 brake kit in the near future!!

[infinkc]

id get DBA slotted

who needs brakes when you can just reverse thrust your turbines....

[alias747]

Yeah my stage 6 needs some new brakes too...

But really, I have heard that you should just pick up the cheapest rotors you can find on ebay. They are all basically the same thing. You can get a set of 4 for a little over 200 shipped. SCORE. I gotta do my brakes this summer too and thats what I plan on doing.

cut a hole through the floorboard do some flintstone action. =]. thats deff. the best way to stop a fast car.

[Racer Doc]

Ah, I am relatively new to the S4, after reviewing the "stages" I see that my car was built up to a stage 3.

So I understand why you gentlemen pounced on me.......

I bought all four cross drilled and slotted rotors on ebay. They've worked fine (knock on wood) for awhile.

i need to pick up new rotors soon as well. i cant decide between regular slotted rotors, drilled rotors, or a drilled slotted combo. what is best, what is worst?

I would think drilled and slotted is best. The cooler the brakes, the better, and with both cuts working in your favor I'd expect that to be the coolest.

I recommend Adam@SPP's rotors! I have them on mine and I love them.
Hes got a group buy in this thread:

i wouldn't recommend ebay rotors... mostly because the rotors are probably from china... and chinese standards for metal are crap and i've seen some f-ed up ebay rotors warped to shit after road racing on other vehicles.

supposedly, cross-drilled rotors have a tendancy to crack, but i've only seen that once on my buddies supra... but he was doing this crazy track out here... he basically slammed it to 120 and then back down to 50 or below for turns over and over again. it was actually pretty interesting to see the rotor the way it was... but i'm an engineer and like to see things fail... mostly for knowledge and it looks cool...

but if you look at most BBK setups, i think a lot of them have slotted and drilled rotors. so, that should tell you something. but it is a different setup and the contact surface area is different.

but also, consider the fact that I live in houston and the ambient temperature is pretty f-ing high here, so more issues can occur with all aspects of a car.

personally, i have hand-slotted zimmerman rotors that i bought from Paul Weston at Weston Motorsports. they cool down pretty good and they keep the brake dust from building up on the pads and rotors. they look pretty nice and feel pretty good, too.

stoptech makes great rotors, im running them now.

[smithm5]

i put brembo rotors on my old coupe.

If i upgrade the brakes on the S4, i will just got with 2 piece rotors and nice pads.

[JayyyyyC]

I would have chosen the Stoptech rotor kit for the stock calipers but I'm really interested in how people liked their ECS rotors. To me, the weight savings are worth it, and coupled with upgraded pads and the slotted rotor option, it should be plenty for what I have planned for my S4 for the time being (stage 2).

However, I have read negative reviews on the ECS kits. I know the satisfaction rate is mostly 50//50 so if people can chime in on this, I'd greatly appreciate it. I'd probably buy the ECS front and rears and save a good bunch on unsprung weight ONLY if the rotors hold up well with road racing.

[Tifosi]

For plain rotors, I will like to try out the Brembos from TireRack



For slotted rotors, I think I will probably go with StopTech Stage II again.

[MiniRS4]

AWE has on ebay for 145 shipped iirc. check it out you can find it on AW too!

[b5s4tt]

ate premium one i have and i like alot. id go with brembo blanks for stock like and a nice 2piece if u can afford
