I'm inclined to agree J. You can look through the Wheel Gallery here on CF and see them both ways. I think it's a manufactureing thing. All they are basicly for from what I understand is to help remove brake pad dust. And looks of coarse.

Nothing to do with brake dust - the grooves are supposed to help aid the dissipation of gases when the pads are under extreme heat conditions, reducing the chances of brake fade. They also help 'cut' the surface of the pads removing any residues that get baked on under high heat.
The holes are also supposed to also help dissipate the gases, but the downside is you get a reduced surface area and possible weakening of the disk (cracks can form between them)
Then again some people just put em on for show
Looks very nice!

So as far as the grooves go you think it's a manufacture's choice there?
Thanks Eakster
I'd be in the show category. Not a tracker.

Proper slot direction.
ZumZum was correct....... if you're planning on giving your brakes hell. Hopefully the ones I have will be fine for a weekend car. Learn something new everyday!

Yup, CE's are special...does anyone know if the calipers are actually any different? As in better performing? I wouldn't think so, but you never know...

I have the CE calipers (front & rear) on mine as well...of course, I had to add them later as they are not standard on all '96's. I think one of the reasons they went w/ the lettered calipers was because of the open wheel design of the CE's which, unlike the sawblades, allowed for the calipers to actually be seen. Now, w/ the open wheels on most cars being standard, more attention seems to be given to the "looks" of the brakes.
FWIW, I've heard that the CE calipers (fronts only - the rears are the same on all 96's) offer a slight benefit over the stock J55's but I have no idea what that really implies.

How do you keep your car so clean? How many miles you have on it?
I clean my car regularly myself and i am very picky. I spend a few hours on it everytime i wash it. I even get under the car and scrub my exhaust and scrub the brake calipers and everything. Ive even had it detailed at a nice car wash a few times when i havent had the time to do it myself but yours seems to be clean it every little crack and line! lol
Whats the secret??

I have 87k on mine. I guess it is just the location that makes the difference. A complete detail for evey little piece on the car is $200 here. Maybe i should just get it done one time and keep up with it myself after that...

You may be right, I don't know to honest. The fronts were marked right and left. I checked the center cooling fins to make sure they like the OEM. And they were the way the rotors were marked. I just assumed that was from the drivers view. There I go again assuming........Maybe someone else can chime in on this. I can't see how it would matter really. Perhaps it differs from manufacture to manufacture.
