Bigger rear rotors?

[Sarthos]

Yah, when it's what people need, about 99% of this site is unnecessary. Surely someone must make an upgrade kit, or someone could. Perhaps this could be Tasauto's next item for sale?

Thanks for the clarification Ronald. Numbers don't lie haha. Everyone, including myself would argue that the rear rotors are smaller than the fronts visibly, but maybe its just an illusion due to the smaller caliper, and the rotor is sunken back in the wheel well farther I believe, so perspective is taking effect.

It looks like what I feared though. A larger rear rotor is impossible without modifying the caliper, i.e. a relocation bracket. It seems there are no OEM solutions that make a larger rear rotor a bolt-on affair. Its too bad too because modifying brackets is what stops most people from running larger rotors.

Ronald, what did you do about mounting the Wilwood's in the front? I didn't see any details about that. Were you able to buy a bracket from them that worked, or did you have to use custom brackets in the front as well?

I agree, I think it's definitely perspective playing tricks on us...Because I've always thought that the front brakes from the factory are bigger than the rear! lol..

So far I haven't really been able to find bigger OEM rotors for our cars..But then again I also haven't been looking very hard..And like you said, even if we do find bigger OEM rear rotors, there's a matter of finding the right calipers for them, or how to properly fabricate a caliper relocation bracket to re-use the factory calipers..

As for my front brake setup, yes I had to have a set of custom bracket fabricated to mount the calipers on my BB6 knuckles..

yeah. i figured i wouldnt be able to find nothing that didnt require modding the rear bracket. lol. oh well.

so even with the bracket that came WITH the kit, you still have to modify that to get the rotor to fit properly?

yeah bro, the brackets that came with the kit are made for DC2 ITR application, so they have to be modded to fit..


And is it just me or the whole Page 2 of this thread talks about hub over rotor conversion for rear brakes, swapping front hubs to the rear and running front rotors on the rear?? WHAT??

Def makes more sense to invest more into the fronts... the rears barely get any action, u can tell by the pad sizing. Prelude VTEC calipers + Prelude VTEC Brembo blanks + EBCs =

Think about it... our cars have like a 64/36 F/R weight balance... when u brake, MORE weight gets transferred to the front. I've seen vids of super small cars doing endos. In any case, better to spend $$$ on the fronts if you haven't already. I basically have a Prelude VTEC setup in front, with cheap shitty rotors + pads, and it's still a huge improvement over stock

Couldn't agree more..Investing on better front brakes will improve braking MUCH more than investing on rear brakes...I find that better brakes on the rear tends to give better brake bias, but not as much improvement in terms of braking power...I was about to run the same 4-piston Wilwood calipers I have for my front brakes on the rear, and run a secondary caliper as e-brake, but I'm glad I came to my senses before it was too late

there is honestly no need to upgrade calipers.
unless your turning your car into an auto cross/track day/full race car.

your STOCK calipers, with a qualty pad and quality rotor, will be more than enough
you dont need anything more

No need to upgrade rear calipers? Sure...But upgrading front calipers is an awesome investment nevertheless, even on your DD/street car..If anything, safety should be number 1 priority!!! Better brakes allow you to stop faster (duhh) just in case of emergency situations..I love it!

When I upgraded to SiR-T calipers (VTEC Lude) with a set of Endless pads and 11.2" rotors from my stock 10.2" brakes, the difference was huge...I felt a lot more confident on the road...But after the H swap, I felt that at times the brakes just weren't doing a good enough job...That's pretty much why I decided to go with 323mm front rotors and 4-pot non-floating front calipers...Slowing down from 200+km/h to 60km/h on the highways have never been easier and faster...No funky vibrations, no funky noises..The car just stops...On hard runs, the brakes do not fade or whatsoever...It's a great feeling because with the older calipers I felt like I worked it way too hard at times, while with the new setup I don't have to worry because I'm barely pushing it to its limits!

But I'm still going to install the 323mm rear rotors once I have to replace my rear brake pads...I'll run stock rear calipers first and see how it is...I know for sure it will give me a better brake bias...How much better, we'll have to see....If that's not enough, then maybe I'll go through with my original plan and run the same 4-pot calipers on all four corners of my car and use a secondary caliper as e-brake...But thennn with that option, I'll have to ditch the OEM prop valve and run a different dual-adjustable prop valves, among other things....I might do it anyways just for the fun of it, but we'll see!!

just sharing this info. this application was done on a 3g prelude ( civic/teg bolt pattern ) this guy did a NSX front caliper and a rear caliper from a wierd car but hey it worked. he also had some non oem rotors drilled to the civic teg bolt pattern. this is just to show how far this guy went to get his desires. oh and they did have a member who put an ITR brake booster on the 3g lude with only having to bleed one line(not in this thread).

thanks ronald, hope some others think the same. i'm pushing to get my 13" rotors, twin piston PBR calipers on in the next week.
i run the larger vtec prelude front rotor on the back and love it.

[Shadow1]

right now, im gonna be getting the wagon rotor upgrade. 11.1" rotors with some Acura Vigor calipers. i compared the stock calipers on the CB7 next to the Vigor calipers and there is a big difference in them. ill post some pics of it later on.


upgrading to bigger brakes is ok. but if you plan on getting some drill/slotted rotors that are like 13" wide with some 6 piston calipers on your DD, it would be kinda of pointless. the brakes work off of heat and friction. TOO much heat will decrease brake performance. but not enough heat will do the same.


so if your not tracking your car on a regular basis, your just wasting money. thats the reason im getting the wagon rotors. its an OEM upgrade and my brakes need to be done anyway.

I would love to have the 13"ers on my car. It wouldn't really be overkill... I just can't run 17s around here, the big rotors would add rotational mass, and the slotted/drilled surface would chew through pads on a daily basis. But on the highways, when I'm alone, I usually touch 90 MPH regularly... stock brakes would melt with repeated braking; my setup now is fade free.

Pretty cool! We live in the same area and I've never seen your car lol we should meet up soon!

Agree..Can't exactly go overkill on front brakes..Well, to a certain point anyways lol but after the H swap, I can hit 110+mph with little to no effort, and the VTEC calipers and 11.2" just weren't cutting it anymore...Btw Yaw, which BBK setup are you currently running?

With my setup I find that warming them up takes some time in the cold mornings...But once they're up to normal running temp, it's not exactly that easy for them to cool down either hehe well, not unless you sit still for 30 mins in traffic or something...I don't track my car on a regular basis (not yet), but I do beat on my car on a daily basis, and these brakes are working just the way they should! I actually do plan on upgrading to a set of Wilwood SL6 6-pot calipers if my current calipers ever need to be rebuild (which is probably never, as long as I maintain them well)

But anyways, VTEC Lude calipers from stock calipers is still a major upgrade nonetheless..Matched with a good set of brake pads and you'll notice a huge improvement!!

And going back on topic, so far what ekoo did seems to be the "easiest" option as far as running bigger rear rotors...All you have to do is find a good local fabricator who can mod the relocation bracket that comes with the kit, and voila!

yeah i'm looking for a single 17" wheel for my spare now. no way the 15 will fit over. small price to pay

[F22HB]

Look on vancouver accords .com Amazing rear big brake setup I saw on there. IMO with upgraded pads/rotors it will be more than enough for standard street tires. I can lock up my brakes on the freeway going 70 (not that this is such an awesome thing,lol) with 215 falken's. All I did was flush the brake fluid and replace it with high temp racing fluid and swap out the stock setup for AEM pads and drilled rotors.

Ronald I am running a super stock BB6 setup. The OEM "BBK". I meant not stock as in not the puny CB non wagon setup. I have the BBK setup just chilling at bruno2787's house; he has to re thread one of the adapter brackets. Once that's done I'm putting them up for sale to someone who will hopefully really enjoy + use them.

In any case, money spent on the front brakes is prob invaluable to ur safety and the car's overall performance. Like strong springs and shitty stock shocks, what good is a built H22 when you can't stop? I'd be afraid to unleash the dragon lol. A good car is about having the full package.

well at least you beat on your car man. im just talking about the ones who just drive their car as DD. lol.

but yeah. ill look around here and see what good fabricator i can find in my area. one of the other managers at my job is in school for welding. ive seen some of his work and it looks pretty good.

but i may just stick with my current set up and upgrade the front rotors to the wagon's.

lmao. why do you call it "puny"? is the Prelude rotors and/or calipers bigger?

[gloryaccordy]

Stock rotors are like 10". Prelude ones are like 11". More importantly though the Prelude calipers are like 2x as big as the stock ones. Even w/stock pads and rotors I have yet to experience brake fade, and I def. use my brakes more intensely than the average Joe.

[93F22A6]

I know with stock pads and EX brakes you get fade after about a good 2 miles of 60-100-70-60-35-80 driving. Kinda scary sometimes.
