plus one rear brakes

[fityamaha]

So i need new rear rotors to pass inspection this year and i have been shopping around for a little while. I found a set of rear rotors that were technically a BBK but they just came with an adapter plate to move the stock caliper back so it will accommodate the new larger rotor. i could of swore it was on enjuku but i can no longer find it. I decided on this setup because i know i will never need the stopping power of a traditional 13" rotor BBK in the rear. if someone could please let me know where to find them, it wuold be greatly appreciated. Other suggestions are welcome. Thanks

i dont understand that.

you want a larger rear rotor but you will use the stock caliper?

a larger rotor really wouldnt affect your stopping power. you need more pad surface on the rotor to make a difference.it will fill up the wheel a lil bit more... so it doesnt look like you have tiny brakes.. i would think thats all it does.. i would get braided lines if anything..

[numbnuts240]

i'm not exactly understanding either. if this is just for inspection, just get oem replacement rotors. i've never heard of a bracket that will allow you to utilize the oem calipers with a larger dia. rotor.

also, with a larger rotor, you have to worry about wheel clearance. i don't remember how much space was available between the caliper and the stock wheels (only applies if you still have stock wheels).

[fityamaha]

you are both right. the larger rotor wouldn't particularly help too much with stopping power, only slightly. It is about filling the wheel and heat dissipation. braided lines are getting done with the rotors along with quality pads. I didnt know they made something like this either until i found it and it is exactly what i'm looking for. it enables you to use stock caliper along with the e-brake. and for basically the same price as new standard rotors, there is no downside.

This is for the front, using 350Z track rotors with Z32 brakes, but there is pad overhang.

[bersh240]

why not just stay with oem rotors you can buy at any advance auto/pepboys? now whenever you need new rotors you have to order them.seems like wayy to much of a hassel for something that wont help you at all anyway.but whatever floats your boat sir.

Phase2 use to sell the STK adapters and larger rotors that will allow you to use stock calipers.

^ This also accomplish what you want.

Also, you can use z31 rear rotors with stock calipers, but requires a little more work.

[slow40]

Has anybody tried this or knows of anyone who has done this? Because it seems to me that you would get more stopping power in the rear with moving the caliper out due to increasing the leverage or "moment arm". Kind of like breaking a stuck bolt loose using a cheater bar.

[numbnuts240]

wtf are you talking about? you're trying to compare physical leverage to a hydraulic system. the only thing you would potentially gain with a larger rotor is less chance of that rotor warping due to excessive heat. it would also wick heat away from the pads/calipers. you wouldn't be gaining any additional braking power, just reducing the chance of brake fade.

[OutToWinPAHC]

Using a larger diameter rotor with a pad designed for a smaller rotor leads to pad overhang, so heating is better, clamping surface is reduced.

He said he was wanting to find a bracket to move the caliper out so he could mount a larger diameter rotor right? Giving the actual point of force applied a longer distance away from the actual point of movement will give it a greater force according to physics. And as long as he gets a rotor that will match up right, his clamping surface will be the same as it is stock, only further away, which will cause it to be stronger.

And whether or not it is hydraulic or not has nothing to do with what he is asking.

This isn't uncommon on Miata's and some other cars but on an S chassis I'd stay stock and just wait to go Z brakes all around.

I believe this is correct.

The larger the rotors, the more brake torque they can generate when the brakes are applied. Up front, that’s a good feature to have. But in the rear, too much brake torque can upset the vehicle’s brake bias and cause the rear brakes to feel grabby and lockup prematurely.

Also: http://www.wheelsnext.com/cont....html

Braking torque is measured in the units of pounds-feet. To calculate braking torque on a single wheel, take the effective disc radius in inches multiplied by the clamping force multiplied by the coefficient of friction of the pad against the disc. That figure is then taken and divided by 12.

Sounds like you're playing with fire if you don't do something to upgrade the front brakes too.

[fityamaha]

front's will most likely be q45's but there is no doubt the fronts will be upgraded to a far superior system. But to tell you the truth, a little bit more braking force to the rear relative to the front would be welcome, meaning i wouldnt mind if the braking force split was closer to 50/50 (but not actually 50/50) because stopping would definitely be much quicker. its like when you are braking hard in a rwd car and you shift down a gear and use engine braking. you will definitely stop quicker because your rear wheels have more braking grip to offer than what the factory gives you.
