Brake Rotor Upsizing

My Porsche Cayenne Brembo brakes for my Audi came with 6pt calipers and 365mm rotors. I was able to upsize them to 380mm with just an adapter. Does anyone know if we can do this with these Toyota calipers?

 

could try r1 concepts, but i think i can count on 1 hand the number of people that have done that.

 

The only kits I've seen are full BBKs... I don't believe there is a larger OEM rotor that uses the same caliper on anything

 

I gotta find the manufacturer of the calipers. With Porsche, Brembo makes the rotors and calipers.

 

Are you feeling fade in your current application? A minimally larger rotor may slightly increase brake torque, but nothing leading to a big change... Something along the lines of a 15mm increase in rotor diameter will yield a very minimal torque advantage (even 25mm+ increase in rotor size doesn't yield a huge difference while retaining a non-performance caliper).

You'd feel a bigger difference in fade resistance and torque by switching to a different pad compound.

I'm not sure who makes the 3rd gen brakes, but as per another thread on here the 2nd/2.5 gen brakes OEM supplier was Advics; so that may be somewhere for you to start.

If you want a legitimate upgrade in stopping power, I would suggest looking into full BBK's from either PowerBrake or Alcon

 

Brakes are fine, purely aesthetics. I just bought 24s that will make the brakes look small.

 

The Hybrid brake don't help either if there was an upgrade size. I'd you have a hybrid.
Stop pressing the brakes with only your big toe. Using your whole foot makes a difference in stopping.
