I keep going back and forth on this and just wanting some opinions.I currently have a set of r34 (im pretty sure) sumitomos on my stagea rs4 daily/street hooning car that's mostly stock. They're nice and quiet with decent stopping power but I have felt them fade a bit doing some spirited driving coming down the mountain.

recently I found a full set of z33 brembos with stock pads, rotors, and lines for a really good deal and picked them up.

Is it worth swapping to the brembos or should I sell them and buy slotted rotors, better pads, steel lines and fresh seal kit for the sumitomos? Wanting to get around 450hp with some light track use in the future.

I would start with a complete bleed of the brake system too with fresh brake fluid.

Most fade people get on the street is either from pads not suited to the driving, or old fluid that isn't happy anymore.

The fade only happens going downhill on the togue after a few hairpins. But my pads probably have 2mm left in the front so no matter what I'll be swapping those and doing a fluid change

The Z33 Brembos use a 324mm disc as well, would be much better than the 310mm R34 GT-t Sumitomo setup.

I run the Z33 Brembos on my shit box and it seems to stop well at Sydney Motorsport Park's GP Circuit. I have only 437kW, so not huge power but can happily do 2x hot laps before experiencing any brake degradation. Currently using Intima RS pads (superseded model).

    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
