Maybe you guys could try greasing the edges. I've heard people complain stock S pads were a tad squeeky before and i was a bit surprised by those complaints since mine never make a sound. I know we are all on different pads but cant hurt right?

Also cleaning up those sliding pins may help too. Mine were a tad rusty so i used a wire brush to clean them up and grease them just a tad.

 

And about the SPs stopping 1/2 the distance and feeling like you are going through the windshield, Now you have me wanting to buy them before mine are even worn out

 

Yeah, the Carbotech XP12/10 pads are awesome, but a bit much for the street. After a track day when I drive home I always have to remind myself to take it easy on the brakes so no one rear ends me because I stop so much quicker. Then I switch back to my street pads and it feels like it takes forever to stop.

 

hi, new here.
increased pad area/volume normally means increased heat capacity (pads won’t have same temperature as rotors), decreased specific pressure on the pads (to have same clamping force), reduced risk of heat spot on the rotors, decrease energy per area for the pad (each material has its limits related to energy/area)
i am considering a 6 pot properly adjusted, obviously. As pad pressure distribution, pad slots and so on will have significant effects.

if this will make enough difference for you setup? I have no idea, would need to setup a proper temperature measurement through the sections and verify. Maybe your issue is more related to brake balance (are the rears temp way colder than fronts? Or vice-versa)

 

The brake balance is good in my car with my pad compounds. Ultimately, it comes down to asking a lot of the brakes on track due to the fact that they were originally engineered for the lighter 370Z. The original question was if it makes a bigger difference to have bigger rotors or bigger calipers.

 

I would say, it depend on the situation. Probably, bigger rotor, improved fin design and material that can handle better the temperature changes.
brembo has some new fancy designs that dissipates more than the curved fins.

but if the problem is more related to thermal cracking due to hot spots, simply going to bigger rotor may not solve the issue.

 

That seems to be the consensus that larger rotors are more beneficial. Probably a lot cheaper too in most cases. Or we could just get cars that weigh a lot less. I don't know why car companies won't spend more time trying to make their sports cars lighter. That would solve so many issues. Instead the trend seems to be to just throw more power at everything.

 

Have you ever seem someone throwing a brake bar on that? Or else a brake proportional valve (more likely to fit)? To brake on the most efficient way.

i would like to run some test on your car, if I had a VBox and some thermocouples.


new vehicles are heavy or BRZ/Miata. I didn’t like those, and I don’t know why. That’s why I am looking for a G37 myself

 

No need, the balance is actually pretty good. I take brake temps on the car when I track it.

 

Saw in other post that you run already different friction materials on front and rear. Must be sufficiently balanced.

Sometimes on formula cars they setup a specific balance for each deceleration level, which for sure it’s a overkill for track days.

 

I've experimented with a lot of compounds over the years, but I can't take credit for this one. Spencer at Z1 recommended the last Carbotech set up and it works great.
