1) Lose the all caps, and let's get some punctuation.

2) I'm assuming this is a street car. You don't need anything more than stock rotors or if you want, you can get Brembo replacement rotors.

Anything else is wasting money, unless you want to pay double Brembo prices for Power Slots, just to have a shinier rotor.

Checked on the prices of new plain old rotors, and around here people want 69.99 a piece, so i went for the TPMs from Slowboy racing for 134 for the pair cross drilled and slotted.

I personally wouldn't get them cross-drilled. They tend to form stress cracks. Power slots only if I were doing intense track racing. Even then I'm reluctant to get them that way. I'd stick with the stock rotors.

i just recieved my rotors from slowboy racing about 1 week ago. ill PM you when they are on and tell you how they feel.

Powerslots aren't even worth it for "intense racing".

If you're doing wheel to wheel work, you go get 6 piston AP calipers with some big ole heat sinks, and screw the stock DSM Braking system.

Cross drilled rotors are original equipment on Porsches. Good enoungh for me. I've got 'em and they're great so far, especially in wet conditions.

I'm on the same boat, I need to replace my rotors and don't know if stick with the Stocks or Upgrade to Cross drilled, I've also heard about the Cross Drilled Cracking... but doesn't it help if you get "Good Brand" Brake pads? or that has nothing to do with this...?

Brakes work by converting kinetic energy into heat. The heat comes from the pads rubbing on the discs. That heat is dissipated to the surrounding air, although initially and for most street driving, the pads soak up the greater portion of this heat, and the rotors next in line. The pads pass heat to the calipers and brake fluid. The rotors conduct out to the wheels, wheel bearings/grease, and spindles.
In the olde days of the sixties, when disc brakes finally made their trek from mining equipment to farm tractors to racing and to street cars, they had an odd failing traced to gasses from the overheating pads forming an insulating barrier between the discs and the pads. Drilling and slotting were devised to "sweep" these gasses away: another benefit (for those of you who've experienced the first stop in a Datsun 510, in the rain, with open-slotted aftermarket wheels mounted) was to clear off water much more quickly.
With modern pad compositions, much of the gassing problem has been eliminated- so much so that for street use, slots and holes are as much racey-looking as functional. You'll see much more performance benefit in upgraded pads than you will in slots and holes, although you'll more easily see the slots and holes.
I don't personally know to what extent drilling is or isn't a hazard on the street.

What ever. All I know is there's a definite improvement over stock rotors in wet weather.

Mmmm... Riceboy mentality at work!

We call it the placebo effect.

 

[jtmcinder]

Technically, it's more likely to be due to cognitive dissonance, but it's a similar idea. Placebo effects are when you "feel" better after some change, on the assumption that the change would help. It's plain, old, top-down processing. There's no ego-defense involved. Cognitive dissonance, on the other hand, is when you change your belief to protect self-esteem, often by "proving" to yourself that you really are internally consistent and make good decisions. So, for eample, you make yourself believe that the brakes now work better to "explain" to yourself or justify having spent the extra money.

The US military has long used cognitive dissonance to make soldiers love the Army. Boot camp is hell so that soldiers say to themselves (metaphorically speaking): "I must really love the Army ... why else would I have put myself through this hell?"

Cognitive dissonance is the main reason why you should not take the recommendations of others very seriously, unless they are backed up with some objective data. Very few people have egos strong enough to say: "I just spent a ton of money on these parts and they're crap."

Not that anyone really wanted or needed the Intro Psych lesson. But it's office hours and everyone seems to be out killing deer instead of getting ready for finals. We are Penn State!

WOW!?!?! Big words...... Didnt know id be a ricer when i bought the cross drilled and slotted rotors because i found them cheaper than the plain brembo replacement rotors, and yes im upgrading my pads to ceramic cause my friend whos a mechanic said they work better with the cross drilled and slotted rotors.

Thanks for the info and the insults...

I'm very impressed. Not only are you an expert on automotive braking technology, but an outstanding psychologist. Seeing that PSU could use a new football coach, perhaps you could do that as well.

Oooo. Low.

But thanks for the other kind words.
