Does anyone know if there is a LARGER rotor upgrade for the OEM Brembos? Need something a little more than 12" to fill in the barrel gap on my LMGT4s. Thanks for your help ahead of time.

P.S. For you fire starters, I did search and came up with nothing.

Brembo GT would be considered an "upgrade" to the OEM brembos. Otherwise, you're looking at every other BBK.

It's not a pure rotor replacement, you'd be looking at rotors, calipers, pads, etc.

This^^^^ Think about where your calipers are mounted. Has nothing to do with rotors, so to just "upgrade" to larger rotors, you would have to have special brackets made to mount the calipers wider out (if that makes sense). Which I would NOT recommend doing!

What would a larger rotor accomplish? The pad size would still be the same.

This is a strange question...

I am gonna guess by his statement "Need something a little more than 12" to fill in the barrel gap on my LMGT4s" that it's strictly for looks. Doesn't make a whole lotta sense to me

OP: If you want larger rotors, buy a BBK

Larger rotor? Sure but the position of the caliper is fixed. How does that work out?

That's an easy way to say what I was getting at

larger rotors make it easier to stop, has nothing to do with the size of the pad.

Using this picture as an example, I would guess the pad is using upwards of 80-90% of the rotors surface to stop. But what your saying is putting a larger, heavier rotor with the same caliper pushing the same size pad will stop better while leaving a larger percentage of the rotor surface untouched?

Ok, basically what i want to do is put a 14"-16" rotor(considering the oem rotor i believe is a 12" rotor), to fill in the gap between my caliper and barrel on my wheels. How is that a strange question? I know you'll need to relocate the caliper to accomodate the larger rotor, but going back to my original question does any company make a kit that will allow you to do so? This has noting to do with pad size. Same concept as adding a BBK to any oem vechile that doesn't have one. The OEM Brembo calipers will be sufficient to what i need them for, i basically want a larger rotor to fill in gap, no need to spend 3k+ just for that. I have a front bbk set of 14" wilwood rotors and wilwood 4 Pot Calipers, but would like to keep using my brembos because of the rear set-up.

Why not just powder coat the rear Brembos you already have to match the Wilwood front 14" BBK and be done with it??? It should work fine if not better then the stock set up and get you the look that you are after at the same time..

I think it is a win win...

The bigger rotor won't fit, don't even bother trying.

the increased radius of the rotor creates more leverage to stop. imagine your steering wheel was half the size, it would be more difficult to turn. now imagine it being twice the size.

You'll need a bbk....if you want to increase the rotor size and leave the oem caliper/pads you'll only be hurting yourself (hopefully not literally) since the pad will only cover a portion of the rotor

people do this all the time in the VW community. they have special made brackets that lets you mount the caliper out. Creating more stopping power. Once again the pad size doesnt matter.

Pic/info on that ?

Not to be an *** but Zs aren't VW and I've never heard of ppl doing that

trusovici

info on what? its common sense. you ever try and stop a small rotating part with your hand? like a drill etc.? its very difficult. Now imagine stopping a larger diameter rotating part spinning at the same speed. its easier.

And Can i Ask you what the manufacturer has anything to do with physics? Yes the Z isnt a VW....

eh just 14-16, no big deal.

i recommend selling the brembos and getting a set of g37/370z akebonos. large calipers, large pads, and upgrade to a better pad and your good to go. on the plus side they're fairly cheap too. all you need is the caliper adapter brackets

Makes sense. Never thought of that. But what about the added unsprung weight?
