Is there any options other than OEM? The OEM rotors are like 90 for the front and 95 for the rear each. Most aftermarket like Stoptech and Power Slot are cheaper and should be comparable to stock ones. Just wondering if any of them are legal for STR.

 

14.6 BRAKES

A. Cross drilled and/or slotted brake rotors may be fitted (same
size/type/material as standard) provided all such voids are within the
disc area, and comprise no more than 10% of that area.

 

oem blanks, oem pads and ATE superblue brake fluild here.

It will kick abs on with the 255 kooks. Theres no reason for anything "better"

 

Centric OE type rotors cost about half that. ($50 each)

 

There's also no reason to run DOT 4 fluid.

 

I just run the Valvoline DOT 3&4 stuff. With OE pads and rotors.
Never ran into issues, even hot-lapping the car on a fast course at Sebring with a co-driver a few weeks ago. Clutch was the first thing to start getting hot.

Good to know about the cheap blanks though, thanks!

 

if i remember correctly, napa rotors are like $33 each

 

This is an STR discussion, hence no need for DOT 4.

 

And yet, there's no reason not to use DOT 4. Having a higher boiling point doesn't degrade the performance at lower temperatures. And honestly, if you get into a situation where you can do back to back fun runs, it is possible to get your brakes very hot.


PS - I personally don't like the blue crap because the blue never goes away, but I'd use the yellow version (TYP200).

 

For what it's worth, I've heard of (over-)aggressive left foot brakers fading their brakes during autocross runs, so that's one possible justification for using DOT 4.

Also, I agree with John -- why *not* use DOT 4?
