They do serves a benefit. WEIGHT!!!!!!
Can someone answer my question?

AWR engine mounts generate more than stock vibrations. That info is easily available by search or browsing anywhere in the Protege section.

I know they do. But just want to make sure if anyone here are running them and have the same problem with the rear 3.5 wing

the wing on your car (in sig) is the 03 wing, which is supported in the middle. the 2003.5 is not, and anything that is nearly 4' long is going to shake when vibration is applied.

Lol, ignore my picture. It is not updated. Thanks for the reply. I though mine was defective or something lol....

didn't do too much, drove it around today...getting ready to order the CS downpipe Monday morning if they have any in stock. Then the J spec intake cam and CS exhaust cam next month.

That's the ones I was thinking about getting I saw a set with pads and cross drilled and slotted for 118. How do you like them like you haven't had any problems with them? I'm iffy on some ebay stuf. The other ones I found were the rotorpros for all four 275. On protege garage

I've had two sets on my car. The ones I replaced a couple months ago and the ones I have now. The anti rust coating in the middle and sides is great. The only reason I replaced mine was because I wanted brand new, fresh brakes all around, pads and rotors included. They have been nothing but good to me.

Yea I saw some cross drilled and slotted with pads for 257.80 for all four with free shipping.

I'm not sure about Porsche, but I have read an article interviewing the Chief engineer @ Ferrari, who stated that they only "cross-drill" their rotors for style/aesthetic purposes. NOT function. O and physically drilling into rotors as most after market rotor companies do, structurally weakens the rotor in turn...
BTW, Ferarri doesn't cross-drill their rotors, they are forged with the holes in them, much stronger that way. I would guess that the same is true for Porsche.

pic of meatyness of rubber.
My understanding is that really high end cars that are designed for actual track use (though most never are-i.e. Porsches) employ cross-drilled/slotted/ceramic/whatever rotors for better heat dissipation and air circulation, not weight reduction as some have stated. When cheap-o brands adapt that to pedestrian cars it doesn't always work well. Several years ago, I had a 95 Probe GT that I installed eBay drilled "Brembo" rotors and they warped within a few months of regular driving. Ever since then I have avoided them. Solid rotors work just fine for 90+% of us.

That doesn't have to do with heat dissipation at all. Like I said before, the only reason those rotors have the drilled/slotted design is for weight purpose. The only reason they where ever implemented in a car was when brake pads where made with asbesto. They needed to dissipate the gas created cause of asbesto since it caused brake fade. Formula 1 discs are completely solid. No holes, no slots, why? More surface contact and cause the discs are made with an outstanding cooling system. There is no other way to cool the brakes than just install a canal for the air to get into the discs thus increasing air cooling flow, and increase the pads contact surface. I have raced my RX7 with slotted discs and plain discs. They both performed the same.

I'm sorry, but none of this is really accurate. I'm not saying that one is better than the other (I have no evidence to prove so either way), but the logic you're employing to say so isn't sound. It has nothing to do with pad material, and VERY LITTLE if anything to do with weight.

Neither do I. The thing is that's how it has worked for me. They performed the same. No actual performance gain between them. Brake fade was around the same. So for me they are just for rotational mass reduction. Again, I have used them in racing conditions. Adding the air canal and increasing the pad size with a bigger caliper worked for me better than using slotted discs.

Yes, a vented rotor will always outperform a solid one, and a larger diameter rotor and bigger pad will always help too, but you can't unilaterally say that slotted and drilled rotors don't serve a benefit. Prove it beyond one subjective experience if you're going to make that claim. Also, since you say they were good for weight reduction, what was the saved unsprung mass by going to a drilled rotor?
I dropped 6 lbs switching to a lighter wheel, and it definitely makes a difference, but being able to say that drilling a few holes in a rotor couldn't amount to more than an ounce unless I'm really missing the boat.

They do serve a benefit, like I said, is just weight, in other words, less rotational mass. Nothing more.....

again... how much? quantify it.
and if there is not benefit in brake fade resistance or performance, prove it. EBC claims something directly in conflict with your claim, and their ass is on the line with that statement. Prove it.

Shut up and take it to another thread.
