@newbie69@Roscio Dear Tuning Guru's, As a brake upgrade to golf 7 7.5 clubsport brakes (5Q0615301C) which way should they be fitted on the vehicle.  I have looked at youtube videos and also on the net with people giving different suggestions? Is it depending if the vanes are straight or angled?

My understanding is that if the internal vanes are directional/curved you'd need to install the rotor so that the outter tip of the vanes is pointing/exiting to the rear of the car, so that dust is expelled easier with the centrifugal force during rotation. The other way round the vanes would just suck in dust and overall cooling would be inhibited over time.

If the internal vanes are straight, orientation makes no difference obviously.

I believe the Clubsport S rotors have directional internal vanes but the issue with those rotors, as with other VAG OEM rotors is that as there is only one p/n, not a Left and Right one which means one rotor will always end up being installed in the wrong direction.
That's the reason probably some Cupra owners with the optional Brembo setup that have really pushed their cars on the track have reported one side (rotor) being bent and going wrong over time (i'm guessing the one with vanes pointing to the front).

I haven't done brakes on the Superb but for the money the CSS rotors cost, and the lack of a proper Left and Right item, I'd choose another aftermarket solution. Even if typical road use is not enough to showcase the lack of orientation my OCD would hit hard seeing one side being installed the wrong way

Thanks, knew I could get some sense from you guys. But you haven't changed the rotors on your car, with all the modification I am surprised!  Do you not think that for me with only a Steinbauer box it's actually not a modification that is value for money?

Not really. The 280/272 has already 340mm vented rotors as stock so the benefits of the Clubsports discs are mainly aesthetic (drilled is not my cup of tea tbh), and the 900gr weight saving is not worth it alone. Maybe as a OEM+ replacement if they needed replacement but it's not that time yet and at 400EUR I'd be looking elsewhere. Definitely not going to improve performance alone.

As a cheap and effective approach that would provide better bite and reasonable endurance you should be looking for: pads, fluid, lines, leaving rotors for the end.

Even a proper big brake kit might not have that much of a dramatic improvement in braking distance, but it would provide better feel and most importantly: consistent performance hard brake after hard brake where the OEM or half-upgraded setup would start to fade. This is not a scenario that I'm encountering at the moment though so I've kept the OEM setup.

Really appreciate your in-depth knowledge and fully explained reasoning whether to up-grade or not and the route to go.  Thanks again.
