Sport/nismo brembo GT front caliper upgrade

fryzia23

Thinking about swapping out nismo front calipers to brembo GT caliper upgrade over my z1 2 piece rotors. Does anyone know what pads available and where can be purchased? Specially looking at carbotech brake pads. Also its been a while since last thread so if anyone has extended period of time tracking with these calipers, is it worth the upgrade?

You should probably tell us what sort of driving you're doing, what mods you have, and what tire set up

Well the car is mostly for track use, it has GTM supercharger with over 515whp and 390wtrq, fortune auto 500 suspension coil overs with 16k/12k springs and running re71r at the moment. Z1 2 piece rotors with Carbotech 10/8 XP pads. Also running brake cooling ducts. My issue is that I get brake pulsation after ~2 days of use from front rotors. I assume is just pad deposits from excessive heat. It only happens at low brake application. Full braking is smooth. Rebedding does not help. Was going to go up to XP20/XP12 next on stock calipers but wanted to know if brembo caliper upgrade would be worth before spending tons of money on full bbk setup.

Have you considered buying temp stickers to stick on your stock calipers, see how hot you are toasting them?

If it’s over oem size rotors, the benefits I can see would be the GT calipers are bigger heat sinks, and may provide better/finer brake modulations at threshold.

To be honest, especially at your power level, I would do full setup (calipers and bigger rotors) for higher heat capacity.

I have never tried the temp stickers. Have a event coming up end of July so might give a look. Obviously I would love to get full BBK but I'm shopping for a house and spending 7k+ on the car right now it wouldn't be a wise choice. So just looking a good alternative at the moment that wouldn't break the bank. Another issue is that I can't seem to find where to purchase pads for the brembo calipers.

I used to get the same thing and tried many ways to prevent it when I switched to Frozen Rotors blanks seems to have solved the problem. I don't think changing the calipers will do much to change that. Add another minute to your cool down before you chock your car in the paddoc.

Light weight rotors (2 piece) are great and have a lot of benefits. But they do have drawbacks. Dump X amount of energy into half the mass of steel the temp change will double. Making warping or other damage much easier, but for race teams swapping rotors out daily is just the cost of doing business. I don't have the funds to do that so I'll stick with my cheap heavy rotors that last a few weekends.

There is a guy in the track section who had similar issues with the z rotor kit. I would replace the rotors first before getting a full bbk.
Racing Brake, DBA, and stop-tech offer two piece, bolt-on solutions that seem to hold up better to track abuse than the z1 rotors. Interestingly, they are all a pound or two heavier than the z1 rotors. Could be something to that...

Since its my 2nd set of z1 rotors and had the same problem the first time, it did cross my mind.. why are they half the cost of the other reputable brands? Possibly that's the way to go in my case.

If you’re overpowering the z1 two piece rotors its time to go more than a caliper upgrade

Its prolly time for some AP racing radicals

I saw on FB that one of the GridLife time attack guys was having issues where his Z1 2-piece rotors would separate; if I recall correctly it happened on more than one set as well. However, I'm not sure how hard his driving is compared to yours but it's still something to be aware of.

Instead of stickers- I use infrared temp reader. It will show if temperature is an issue and helped me to pick correct pads.
It can be bought for $40 or something...can be used to take tire temps too.

I've had no problems with Racing Brake 2 piece rotors.

If I read their website correctly, the racing brakes are 3mm thicker than stock? So even more mass to dissipate heat, but not the weight savings of z1

rb is twice the price tho!

Less weight, more problems. More weight, no problems. Want do you want?

I've reading up and I think I am going to pull the trigger on racing brake rotors. Which pads are you running on the track? thinking going XP20/12
