When I had my Saab I warped the stock rotors, had them turned and warped them again so I bought a set of front/rear crossdrilled rotors off Ebay for cheap, and upgraded to semi-metallic pads all the way around at the same time.
The initial bite when the brakes were cold wasn’t as good with the Ebay rotors but once they warmed up they stopped much better than stock. That might be more from the pads though.
When I sold the car the rotors were still in good shape with no cracking or warping after ~25k miles.
heres my take on this. im speaking from experience. i bought slotted cross drilled vented “brembos” from ebay for my eclipse. they went in 3-4 months. dont buy random ebay shit, because its shit. if youre going to sell the car, just go to napa and get oem bits and leave it be
Yeah, I’m just gonna go with the Brembo kit to give myself some reassurance.
i thought mine were as well. the boxes were marked brembo and there were stamps on the rotors, but they were fake. they cracked around the holes and warped on me. which means theyre fake, and cast THEN just drilled. you want to get ones that are cast with the holes, those dont crack open
So the Brembo slotted/drilled are ok, or do they have a tendency to crack as well even though they’re quality rotors?
Real brembos are fine, just dont buy them from ebay. Then you dont know what youre getting yourself into.
drilled rotors will crack, regardless of whether they are brembo or knock offs, i had brembo drilleds on my old mk2 VR6 and they had like 30k on them and they started to crack, it happens. they are more durable yes, but drilled rotors will crack, its inevitable. probably the only cross vented rotor that will hold up is the Carbon/Ceramic on the porsche cars, ferrari, lamborghini.
So then slotted is the way to go?
heres a link to the kit I’m ordering
no for an average street car, blanks with street pads is the way to go.
but the brembos made in italy
mine are crossdrilled, but the thing is, theyre cast with the holes. as long as the brake rotors are cast with whatever(slots or the holes) theyll be fine
T would go Brembo slotted or blanks. If you’re not auto-xing or road racing the car then Brembo blanks should be fine. I would be more worried about the pads. Street pads are designed for much cooler temps than repeated hard braking produce. A good set of Hawk, Bear, EBC or similar pads are more effective at higher temperature and will not fade as quickly. A drilled or slotted rotor is a crutch for poor brake pad compound. Of course in a racing enviroment every little bit counts. If you can increase your rotor diameter cost effectively than do that as well. It will make a big difference in braking power.
you really do listen to what everyone says… ive had zimmerman, ive had brembos, they all crack overtime. when depends on how you drive the car… the heat cylces are what kill the rotors.
I did some more research on 3zc.com. MK4 is right, the drilled rotors really do crack and people have even reported warping after only 1 track day. That, along with the fact that theres a disclaimer on certain sites that carry the drilled brembos, is enough for me to stay clear. I’ll be going with slotted rotors w/ HAWK HPS pads. Z1 doesn’t offer blanks with the kit I’m buying.
i did what the instructions on them told me to do for heat cycling. they should be okay. i mean, brakes wear out, i know that and its ok. if these last me like 60-65kmi like the OEM’s did, its fine. ill just get another set later.
no thats for bedding in the pads and rotors, im talking heat cycles like stopping for high speeds over and over again while allowing them to cool for a moment in between, or autocross, or track use… no what youre thinking at all.
i dont think his audi has ever seen track time
Watching some stuff on ebay right now :ninja
