I am planning to upgrade my break rotors to Brembo slotted.



I emailed the guy on the website that i am planning to purchase these from, and asked if these were genuine Brembos, and he sais the fronts are brembos but the rears are a differnt brand. He sais brembo doesnt acctually make a rear rotor for the rx7. Is this true?



And i asked him if it comes slotted or does he slot them, and his reply was, "I have a company that does the slotting or drilling". Is that bad or good?



What other question should I ask him?



Any input would be appreciated!

Call Brembo and see if they make such a product for the front. I think he is having the same company do the front also.

Well, looking at the catalog, all the rotors for the FC are not cross drilled or slotted. It also appears that they do not make rotors for the 4 lug RX.



Front - 25362

Rear (vented) - 25621

Rear (solid) - 25866

I will call them Ronin, just to make sure, thanks.



Jef, looking at the catalog, do they make rotors for the 5 lugs?

But without slots of holes right. Stock replacement Brembo.

Some guys machine replacements and try to sell them as "Brembo Slotted/Drilled"

Exactly Ronin. They only make rotors for the 5 lugs. Stock replacements.

Hmm I see. Well I personally think that stock replacement Brembos...(is it vented? or just solid?) would be enough for my use as of now. Im just streeting it, and im not gonna get into tracks anytime soon. But I just thought might as well get slotted now...



You guys think stock brembo replacement is enough?

They should be fine. Most brake pads now adays have a slit in the middle of them that does essentially the same thing.



I would get the vented rear rotors.

why are only the rears vented? or are they both, but the rears are the only ones that you have an option on?

The rears are the only ones that come with the option of solid or vented. The front are vented. I am sorry if I made this confusing some where.

And this rotor is fucked.



Just wanted to add that https://www.nopistons.com/forums/pub...IR#>/smile.png

wow, that is f'd up...lol.

damn was that like metal on metal for 5 yrs or somethin >?? lol geez

yeah, but if your car came with one, you can't substitute the other for it without getting different calipers. non-vented rears had a narrower caliper, and vented rear disc cars had a wider caliper. make sure to look at what yours is first. THEY ARE NOT INTERCHANGEABLE. all FCs had vented front rotors. The only difference in the front is 4/5 lug. all the 5 lug rotors are the same, regardless of wheter you have 1 or 4 piston calipers on the front.

also, rear calipers aren't cheap. a stock reman for my GXL (vented rear) was $90 or so, while remans for the front (4 pistons) were only like $36 apiece. It's cheap to upgrade the front to 4 piston if you don't have them already (mounts are the same), but the rear you might as well leave alone if you don't have vented already. Unless you have a spare $180 just for stock calipers.

I didnt realize there was a size difference in the vented and non vented. I havnt seen any with non vented rears.

Wtf is with that rotor?? lol



Oh I see. Good to know , thanks lxk199. So the stock calipers on a 10th anniversary would be vented im guessing? Therefore the calipers would be wider? Should double check though.



I looked at a lot of websites that sells brembos with the right

SKU (25362) (25621)



and they are going for about $34.29 (front) per rotor, and $71.21 (rear) per rotor.

They are both vented.

Is that a good price range? too cheap? too expensive?

Tirerack.com is a good place for brakes. Even upgrades.

Tirerack doesnt have rears for sale.



coximport.com and speedycarparts.com has both front and rear for a bout the same price.



You guys heard of them?

All TII's (so 10AE included) had vented rears, but it doesn't hurt to double-check what you have. The vented calipers AND carriers are wider than non-vented, so you have to have both, but if your car is a 10AE you should be made in the shade.

Those prices seem about right for rotors. You MIGHT be able to find a little cheaper rears, but the fronts are right on par. I have all Bendix lifetime stuff on my GXL and I paid around that much.

Nice to know. Lot of help I appreciate it!!

if you want sloted rotars get powerslot. They fit right up. I've had no problems with them. but thats my 2 cents.

Do not buy brakes off ebay.



That is all i have to say about that. brebo doesnt make a slotted or drilled rotor for FCs

Brembo does not make slotted or drilled brakes for the stock sized rotors for 2nd or 3rd gens. Brembo rep told me they are either real brembo blanks that a machine shop slotted or drilled out. He said lately they are fake blanks to start with because machining time costs too much money in the USA for small shops. The new batches are coming from china. They are cast chinese rotors and drilled or slotted or both in china. The boxes are fakes too.



Genuine brembos only come in blanks. Previous to 2002 they had only fronts and did not offer rears. Now they off rears. Please see attached file. These are genuine brembos I ordered from tirerack.com



B25362 are the fronts

B25621 are the rears.



These part numbers are for a TII or NA GXL/others wtih 4 pots and use the vented rear rotors.

Now Im confident in buying the "REAL" brembos. As long as I know the part numbers and what they look like, im sure I can do the rest of the research with ease. Tirerack seems the right place to go. Ill try them.



Thanks Guys!

I think the master cylinder is different between the single piston and 4 piston front caliper models.

yes, but I am almost sure you can use the smaller master cyl with the 4 pots, no problem. My old roommate's 89 GTU had the 4 pot conversion, but I'm pretty sure it still had the 1 pot master cyl.

hrm... that woudl change how far the travel of the pedal goes. Because in hydrualics the X-sectional area of your pump defines the hydraulic pressure you get as a function of force applied. This will affect the pressure exerted on each of the 4 pistons on each caliper...



It would affect how much clamping force you get as well from the braking system.
