Rotors

[DSC]

If I was looking to get new blank (neither slotted nor x-drilled) rotors, is one company's better than the other? Brembo vs oem? Wearever vs APC? (just examples)

If one is better than another, tell me why.

*I have a feeling this is gona be similar to cusco vs obx stb's <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>*

Well, I have used brembo flats and regular flats. Most regular flats wear out a lot faster when using a harder or higher performance pad than oem. Brembos are built to stand up to the excess pressure and heat these pads can provide. Plus I don't think there is a huge price dif, maybe 10-12 bucks a rotor.

It's like wagner rotors, they are cheaper, but 9/10 of them I have seen are already imprefect with breaks etc around the lips on the inside. Not the kind of thing I want to see on a rotor before I go to the track &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'>

Yup there is a difference. &nbsp;The thing about an stb is that it while it is a stress item - it is limited stress. &nbsp;How many cracked/bent/broken stb's have you seen? &nbsp;The only ones I've seen get in this state were due to the fact that the rest of the car looked like an accordian. &nbsp;I've seen plenty of cracked/warped/event broken rotors.

The quality of the steel and the quality of the casting process have a lot to do with the "Brembo" name. &nbsp;For the price difference, I think it's worth it for such a heavy wear/stress item. &nbsp;I'm probably ordering a set next week from Strano Parts ($52 ea. for s14 w/o abs). &nbsp;If you find a better deal, LMK.

what about the one they sell at PDM-Racing. Are they any good?

PDM-racing doesn't sell blanks.

while we're on the subject of brakes, i'm still not completely sold on the "x-drill are worthless" argument. i don't quite buy into the claim that modern pads don't produce the gasses that old pads did to create the need for x-drills.

you guys find any new info on this?

[DSC]

Travis, I think they take much higher temperatures to produce those gasses then back in the day. &nbsp;I don't remember where I got that from but you should have all the same sources as me...

Thanks for the info on the rotors guys <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>

[silvia240]

Hey hippo, we should start up a group buy on those rotors. i am down to get them. &nbsp;Also, are you just getting blanks? caus all the brembo rotors i have seen are either slotted, drilled, or slotted and drilled. &nbsp;And everyone tells me just to get slotted ones cauz they are better. &nbsp;
Also is that 4 lug or 5?

I'm really not totally sold on it either.. check this out from bremobo's FAQ website:

"Why use drilled or slotted discs? &nbsp;
Drilling or slotting discs aids the disc in several ways:
The edges of the slots or holes continuously clean and refresh the pad surface as well as providing increased brake "bite". Additionally, they prevent gasses from collecting between the pad and disc interface.
The disc is lightened, thereby decreasing its rotational inertia.
Improved ventilation increases the disc's ability to shed heat, resulting in cooler operating temperatures


What are the advantages of drilled and slotted discs? &nbsp;
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.


Why are there so many holes in a cross-drilled disc? &nbsp;
The number of holes in a cross-drilled disc is part of the engineered system. Brembo has done extensive testing with regards to the number of holes, their size, their location and their chamfering. This attention to detail is what truly sets Brembo apart in the world of braking. The same attention to detail that is delivered to the Ferrari Formula One effort is a component of the high performance program. The number of holes in a disc is in part a function of the size of the disc and the internal venting (if it is a vented disc).

Are discs with cast-in-place holes better than cross-drilled discs? &nbsp;
Brembo has extensively studied and tested cross-drilling versus casting the holes in place and found no significant effect on performance or durability. &nbsp;"

Travis- performance issues aside, you can't turn drills, they are incredibly prone to stress cracking, and they cost 50% more than blanks. &nbsp;Now the corrollary is who runs them? &nbsp;No racing teams (or privateers) that I've seen in the last 15 years. &nbsp;Aside from that, it is your call. &nbsp;And remember, not "worthless" just cost more/last less.

silva240 - I actually need to get mine too soon to wait for a group buy to form (4 weeks until track event). &nbsp;Not a bad idea though. &nbsp;For the record, when you are buying slotted or drilled Brembos, odds are that is done by a third party. &nbsp;Brembo doesn't drill (although they do cast ones w/ holes... but those are NOT cheap!<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'>. &nbsp;Slots do offer a couple advantages (resist glazing by eating new pad), but they also have downsides (pad life is cut by about 40% and they are more prone to cracking than blanks). &nbsp;Blanks are also hard to find b/c so many people are down w/ the bling bling appeal of drills. &nbsp;Strano Parts (forgot www) sells blanks and is listed as a vendor on 240sx.org. &nbsp;They will be getting my business today or Monday.

30mm 300zx brembo blanks for $60 each!
Local place wanted $120 (each) for noname blanks, hahaha.

[pkw1]

read my post on "I have the worst luck of all human beings" and you'll see that buying good quality rotors are important.

[adey]

...just felt like rejuvenating an old, dead, beaten and rotting post;

If people are buying rotors (brembo blanks from strano parts) PLEASE POST! I'm looking to get rotors asap, and if stranoparts (or whoever) can get us a good (better) price, I'll buy two sets.

[bbp]

I'm definately in on the rotor buy in, I buy 2 sets if it is going to be cheaper! &nbsp;

Anyone? &nbsp;Anyone??

FWIW... I have seen/driven cars with slots/ drilled and from my experieince I would just stick with blanks. &nbsp;They drilled don't last as long and I've seen the drilled rotors come apart after they have stress cracked too far. &nbsp;I'm not convinced the slots actually help, I couldn't tell the difference behind the wheel.

[HippoSleek]

I really like Strano... but BUY YOUR ROTORS FROM COLLETTI MOTORSPORTS IN __, OHIO!! &nbsp;They don't have a website, you have to call them (and it's not a 1-800 #) - but I paid $27 ea. for my front Brembo blanks (+shipping to DC = about $70ish for two front rotors to my door!! ).

Service was great - they didn't have them in stock for the 240, but I still got them w/n a week of ordering. &nbsp;I posted their contact information in a FAQ/Archives topic about parts suppliers. &nbsp;

(please excuse the excitement... I was just very pleased to have found them)

[bbp]

I spoke with Coletti, &nbsp;If we can get 10 pair in on an order he will price them at $29 each plus shipping. &nbsp;They normally are selling for 35 each.

hmm i have tried both Slotted and X-drilled rotor.. i dont; see much of a performance there.. i think the major performance change on the braking is if u use some good pad, or just go with a bigger caliper upgrade then u will feel much of a diff there ... i hope this will help <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/eh.gif" border="0" valign="absmiddle" alt=':eh:'> &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/eh.gif" border="0" valign="absmiddle" alt=':eh:'>

I've got AP racing 6 pot calipers and changing to Brembo x-drilled and slotted rotors helps especially on hot track days.

I did not really 'Feel' it (maybe slightly) but when you really do a brake test, by braking hard continuously on the track and measure the brake distances with various speeds, I actually noticed a significantly cahnge in braking distance..

Not really feeling it, but actual measurement..

Something like 10% change at least..

Robin

Also x-drilled and slotted looks better with 18" rims

Are these only for fronts? what about rears? and bbp are you changing (buying) fronts only, or 2 sets?
If it's 10 pairs total (i.e. 20 rotors regardless of whether they're front or rear) then we have as many as 8 pairs (4 from me, 4 from bbp) or as few as 6 pairs (4 from me, 2 pairs of fronts only from bbp).

shipping though... 8 rotors from Ohio to CA... &nbsp; <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/whatsthat.gif" border="0" valign="absmiddle" alt=':whatthe:'>

[Jim96SC2]

Does blank mean that they aren't slotted/drilled or that they haven't been drilled for 5 lug yet?

non-sloted, non-xdrilled.

[nrcooled]

I am interested in rears. &nbsp;I just had my stocks resurfaced but the are still OEM probally from when the car was purchased

I started thinking the same thing. &nbsp;It may be cheaper to try some local parts stores like NAPA. &nbsp;Rotors are pretty heavy and commonly available so why pay shipping? I also live in Ohio so I would be paying tax too. &nbsp;
I'm going to call around tomorrow and see what I can find locally
