Slotted and Drilled Brakes

[JSTATL]

Has anyone used slotted and drilled rotors on their G? If so what type of performance differences did you see if any.

i have slotted and dimpled, if you don't mind that.

Or just slotted here...I don't know about differences because I also swapped out my factory pads for high performance pads sorry. The slots are supposedly able to help the pads bite though.

I'm not sure...I'm sure they probably have a difference when it comes to heat dissapation but the benefits are probably lost when you consider how much faster you will eat up your regular pads (slotting = shaving the pad). Like I said before they are probably good for autocrossing/racing but hummin up and down 95 and driving in the city, I personally don't know the benefit other than the eye candy factor

Listen to this guy. Cross-drilling is basically worthless other than to look good. I mean it really does look good and all, but its invention came about in high-performance racing back in the day. Basically it allows the burnt up gases, which are much more abundant in high performance, higher friction brake pads, to escape from between the brake pad and the rotor. Back in the days of solid rotors, braking power was drastically reduced as the pads and rotors heated up, due to the fact that the pad would actually "hydroplane" itself away from the rotor on a cushion of burnt pad material. However, you have to remember that these were designed for RACE CARS, who push braking to the limit almost every time they turn. Drilling rotors severley reduces their structural integrity, and even though they may heat up less, thereby reducing rotor warpage, they will crack much easier than solid rotors. You will also go through brake pads like a mofo. Just imagine a cross-drilled rotor like a cheese grater for your brake pads, and you'll see what I mean.
Now slotted is a different story. If you plan on doing any form of autocross or road racing, these are the shit. They expel burnt gases just fine for your limited use of the brakes, will resist brake "hydroplaning" by an incredible amount (even though the effect is barely noticeable until the brake pads heat up significantly), and will not warp or crack (if you get a decent set).

Given the choice between solid, slotted, drilled, or slotted and drilled, I would have to go with slotted, because they are sturdy, hold your braking capacity very well without chewing up your pads, and look better than stock rotors.

Just my 2 cents though, do what you want.

That's what I read too

I was in the car with one of my friends when he cracked a cross-drilled rotor. It was loud as hell. Thing heated up, then he drove througha puddle CRACK BANG! got out, looked at the driver's side rotor, had cracks spidering out from the center. However, the rear rotors, still solid, still pretty damn hot, and still went through the same puddle, were just fine.

I have cross drilled and like them. They haven't cracked and the gold anodized finish is still in tact (1.5 years). They solved my warping problem and really "grab" when you need to stop. I only changed out my fronts because they were the ones warping. I guess it depends on which manufacturer made the brakes as to the integrity of the part. Good Luck on your choice....

Or, if you're like me, buy super brake pads. My brake pads are eating up my slotted rotors way faster than the slotted rotors can scrape back It's a war down there!

I'm happy with the slotted and dimpled rotors, I dont think the dimples do much except add a look to the rotor. I think the slots are gonna eat up pads pretty quick, only time will tell. Thanks to Wood at raceconcepts you too can have these for a very reasonable price.

Yep I have the exact same ones from Wood. Dimples eliminate the integrity issues from drilling, and so far I'm still on the original set of Axxis pads roughly 10 months later.

Passing by here...

I'll agree with the long post above but with one statement;

Cross drillled are more for the street than the track. Only those who are looknkig for a weight savings and are 'up' on maintenance of a race car run them under most conditions. Myself included.

The 'look' for street is fine, where you won't see the higher stress of use on them. Take them to the track often and you're asking for trouble however.

In today's word; Track solid or slotted. Street; whatever floats your boat.

This is true, remember that brakes for most racing cars, from Le Mans to F1 to NASCAR are rebuilt every race. Hell in Le Mans, they swap out calipers or pads 5 or 6 times during the race, at least.

I have the Cross-Drilled and Slotted rotors and the way the wife drives the Galant to and from work let me just say im glad i aint a set of brakes she is hell on them and no complaients as of yet and they have been on from 6 months now and probally have 15,000 miles on them now.
