So shiny

Handed discs. Must get right way around!

Wow. No instructions and many you tubes that contradict !!

Most say slots sloping to rear of car.
Some say slots facing forward to cut into the pad in direction of travel !!


Anyone have definitive answer please?
From a completely unscientific, uneducated, uniformed, but ocd point of view, that looks like it should go on the off side to me. It would appear back to front on the near side I reckon.

So according to supplier they should be as red stripes. So the one in the photo is fitted wrong.

If I understand the majority replies above, this would mean the opposite to the views presented.

Am I understanding correctly??

Seems they want it facing the front of the car... beats me as to why, but I'd go with what they say, they manufacture them after all, not me 😂
 
New vented, grooved discs fitted. Ceramic grease where needed. All brake dust cleaned out. Wheels cleaned too !!

See how it goes. Was quiet on test drive. Need to bed them in for a few hundred miles.
I like drilled and grooved rotors, as the "bite" better than plain rotors.
I've always fitted them to our VW and Audi vehicles, as those always seem to have rather dead brakes. They are noisier than plain rotors, often causing a audible buzzing or fast vibration in the pedal under heavier braking, but that's a small compromise for better brake response.

I can't believe you've fitted the very same ebay special discs as mine this week.
I've had grooved and dimpled discs on another car and, while you can hear the sound they make, it isn't irritating and the brakes feel more "immediate." Which I think will be a good upgrade for the freelander. Although the kit that was on there was in such poor condition that even a return to stock components would have been a massive improvement.
 
Not based on any fact, but my guess would be with grooves slanted towards rear of car, then the inner end hits the pad first & at slightly slower rotational speed. Maybe less pad impact, therefore less noise & pad wear ??

Only real way to tell would to use a Tapley Meter to measure the braking deceleration, and then after a few weeks/months measure the pad wear. Once you have those figures swap them round, do the same tests. You might be the first person with the definitive answer.

Found this site which seems to explain the direction of the vanes is more important. But as you said lots of contradictory info out there.
