Here's the left side of my install of SSBC rotors.

I installed them just like shown here in an article that I found. http://www.carcraft.com/howto/116_0309_brake/index2.html
Again the left side in the article.

Here's another pic from an article in a different magazine, this time the right side.

And my right side.

Sorry for so many pics, but the slots in the two articles are heading in different directions. Which one is correct?

thanks

I r4ally think YOU have it right. But, I'd call the supplier to find out.

You are correct. The purpose of the slotted rotors besides improving heat dissapation is to shed water from the disc. Clearly you want the water to move off the disk working with centripital force hence you are the man! Nice install.

As said, you have it right. The magazine has it backwards... WHY am I not surprised?

The curves should go as you have them to assist in shedding water. The way the magazine shot has it, the water would be pulled back down to the center of the rotor.

Ditto on the nice install. I just put performance rotors on my Honda Odyssey today, very similar looking.

What's all the green goo?

You have it right, but the function of the grooves is more to release gasses that pads produce that can form a boundry layer between the pad and the rotor. The pad one rotation of the rotor with the brakes applied and all the water is gone - grooves or no grooves.

If it makes you feel anybetter....they work backwards just as well as frontwards. I installed them on the wrong side and never changed it.

Here's a reply I got from a guy on a different forum:
Mounting the rotors in the correct direction has nothing to do with the slots on the sides. You mount the rotors so that the cooling vanes inside sweep out when spun in the forward sense. The idea is to fling the air in them toward the outside using centrifugal force, and suck cooler air in with the vacuum created by the exiting air.

Check your vanes, if they are straight, it doesn't matter how they go one, but if they curve, make sure that when the wheel rotates in the forward sense the outer edge of the disk isn't scooping up air.



I verified that the inner cooling vanes are straight, so if this guy is correct, we are both right.

It all depends on the application. The car is the magazine photo is set up for the new SCCA Reverse Challenge Road Course, where cars navigate around the course in reverse at top speeds approaching 38 mph! ::

I would change them.

Think about it... the pads will try to climb the slots as you apply the brakes. This could possibly load the keeper plate that covers the pads and retains them in the caliper.

In reality, it probably will work fine the way you have them. I would turn them around such that the rotation induces the pad to climb inward towards the hub as the brakes are applied and the rotor turns.

Me either. This photo is from a well-known magazine's "How To: Detail A 289 Engine" article. Can you spot the HUGE mistake they made?

Zombie thread- back from the dead. I'll guess on the photo above. Is the fan on backwards?

Bingo. Pretty basic mistake for a nationally well-known magazine. I actually contacted the shop that did the job, and their reaction was "OMG!". Of course, the magazine won't be replacing their archive photo.
