Yep, it turns the pedal into a rock. I have never tried the Castrol SRF, but I can't see why I would when the Endless exists.

Adam, you have PCCB? I personally don’t like PCCB because of exactly what you are describing, the pedal really does feel like a rock. It’s too hard in my opinion. You have to really push on the pedal. Don’t get me wrong, they work, but to me its wasted effort. I get tired, so if I don’t have to push the pedal so hard, its my preference.

I have a mate with a 2-RS, and everytime he gets out of his car and drives mine, the first braking, he gives both of us whip lash from stomping on the brakes to hatd. 🤣. Then he screams, jesus your brakes work 🤣. He’s just used to pushing harder initially on PCCB.

Type III rotors give awesome feel and feedback. They are perfect when trail braking.

Nah, on both my 991.1 with the Reds, 350 steel rotors, Endless pads, and now my 991.2 with PCCB. I know what you are talking about with PCCB firmnesss, but this is a different firm. You should try this fluid at least once.

If it works for Sir Lewis and George on Sunday, it's good enough for me.

The pedal is hard as in very short travel, you can brush over the pedal and feel the friction. More sensitive to pedal pressure might be a better term to use. I had much longer travel and less sensitivity with SRF. Part of that is the proper ABS bleed but SRF has always given me a longer pedal when hot

The modulations is also improved and that is what really put a smile on my face.

Not trying to be a brake fluid dealer but you should try it.

This is random. But yes. We cut the cheap metal cats out. Went catless, he completed the tune and it made good power. The cats were clogged. They were barely a month old.

Your doubt is worthless when you don’t read the entire thread to see full details, including pictures.

Try page 11.

But here’s a pic anyway.

Hi Thermal

Brembo GT-R


My GT-R BBK is at the mechanics and is being installed on Tuesday.

Note the deeper annulus of the Hi Thermal rotors. Not all 380mm rotors are equal. They are also thicker for better thermal efficiency.

Those should last maybe 1 or 2 sessions before they go pink-ish yellow 🤣

🤣. I’ve seen the Nickel turn goldish on cup cars. So maybe that will match the new hats that look more gold than black. 🤣

You’ve wandered into the 991 sub and are a little confused maybe?
