Thanks for the info. I will email the photos to Alfieboy and he will post them for me. This weekend I'll try to figure that out. Thanks Vinny

I think you have the rotor on the wrong side of the car. Slotted rotors should be installed so that the end of the slot on the outer edge of the rotor enters the brake pad first. Your pic shows that the inner end of the slot is entering the brake pad first. The pic below shows Racing Brakes instructions:

What it the torque for the rotor bolts?

thanks,
Also, thanks for the info above! The front set of my Stillen rotors doesn't have the left right on them!

You mean for the 18mm bolts that hold the caliper on?
I also just edited my above post with a pic.

Also remember to wear in the pads to the rotor as follows:
1. make 6 - 10 stops from aprox 35 mph applying medium pressure
2. make an additional 2 -3 hard stops from aprox 45 mph
3. DO NOT DRAG BRAKES!
4. quickly get back up to speed between stops while doing this procedure so the brakes don't cool off too much
5. allow 15 minutes for brake system to cool down
6. after step 5 you are good to go!

I followed the directions & they were very clear. I will call them to double ck. Thanks

Here's what Brembo also says about slotted rotors, I highlighted in red the rotation:

Brembo Sport Slotted Rotors

Brembo Sport slotted brake rotors are for drivers who want to improve the looks and performance of their vehicle’s original braking system without having to change additional brake components. Brembo Sport slotted brake rotors provide excellent stopping power in everyday traffic, as well as high performance street and track driving.

Brembo Sport slotted brake rotors match the vehicle’s Original Equipment rotor’s dimensions and are fully compatible with its hubs, brake calipers and road wheels. Front and rear Brembo Sport slotted brake rotors are available to provide a matched appearance on all four corners of the vehicle, and employ one-piece vented or solid rotors depending on the vehicle’s Original Equipment specifications.

Starting with select castings, Brembo Sport slotted brake rotors undergo the race-born practice of machining multiple shallow slots into the disc’s front and rear surfaces to provide paths to disperse built-up heat and gasses and assist in refreshing the surface of the brake pads. Compared to cross-drilled rotors, machined slots have been widely adopted for racing and street use because they minimize the cracking caused by repeated, high stress, high temperature brake applications. The slots are angled to use the rotors’ direction of rotation to enhance their performance, which makes the rotors side-specific with left and right side rotors. Brembo Sport slotted brake rotors are sold in axle pairs and the easiest way to verify correct usage is to install the rotors on the side of the vehicle that results in the end of the slot nearest the outer edge of the rotor always contacting the brake pads first.

Brembo Sport slotted brake rotors are coated for corrosion resistance to help eliminate rust and offer a bold, aggressive appearance to enhance the look of the vehicle’s road wheels. NOTE: Light Truck and SUV rotors with studs or bearings are uncoated.

Brembo Sport slotted brake rotors are designed to meet the challenges of high performance street driving while adding an authentic, race-ready look.

NOTE: Brembo Sport slotted brake rotors can be used in conjunction with race compound brake pads on the track for drivers’ schools and lapping days.

IMPORTANT REMINDER: Slotted, drilled or dimpled rotors offered as OEM replacements should not be considered appropriate for high-speed track use.

While grooved, drilled and slotted rotors offer an enhanced appearance and add some resistance to the boundary layer of gasses that can build up between the pad and rotor, they are not designed to withstand the extreme temperatures that are produced on the racetrack. If they are used on the track, it is very important that the rotors be carefully inspected and should not be driven on if even minor signs of deterioration are seen. Note, too, that if any products are used on the track they are not warrantable.

Well, the calipers and the bolts that hold the rotor on the hub (if that's the correct word. Are the bolts holding the rotors 18mm? I assume the caliper bolts are smaller...I'd need the torque for all the parts removed to put the rotors on. I don't see these in the owner's manual.

Thanks,
Michael J.

this pic of a slp zl575 shows the rotors opposite of what post #21 says??, but these are drilled and not slotted.

This is a picture of my rotors straight from Stillen. "L" means driver's side, "R", passenger:

That matches MtcWby's descriptions...

Oh, still need all (but the lug nut) torque values!
Thanks...

[hypurone]

To the OP, thanks for getting the pics posted up. I can now see that they are not chamfered. Still nice looking...

I had these on my RX7 and never had a crack in them thanks to the chamfered holes!! I ran em hard at the track several times too. Good to see that they are making them already for our cars!! Do they have the black zinc coating as an option?

[Michael_Js]

I did not see the black coating as an option - I would have liked that

Thanks,
Michael J.

If you call them, they will coat them black like they did for mine.

[Michael_Js]

Well, I already have them and not going to ship them back

Thanks though...they're goin' on Wed.
