It's time I change my Hawk pads and one of my rotors as a nasty groove in it.
I was wondering if any one has had them resurfaced. (Powerslots w groove )

I tried the search put couldn't find anyone who cut aftermarket rotors.

Thanks, Mike

 

Some said they had slotted rotors cut. They said you had to do it by not going as deep and making more cuts.

 

I've cut many slotted and drilled rotors. Most shops will say you can't but that's just because they are to lazy to take the time. You just have to take more cuts and smaller cuts and it works fine. I even drill my own rotors, works great and everybody who sees them dont' believe me.

 

Don't get me wrong, slotted/drilled/etc. looks hot, but I'd put real money down .001% of people drive in such a way that they help.
On the contrary, reducing the surface material on a rotor may slightly increase stopping distances in most cases.

I guess this isn't really the question, I just get off into a rant about useless mods. Sorry.

 

When rotors get turned you are removing material from the width of the rotor not the diameter. The only thing that might increase is pedal travel but slightly i doubt stopping distance would increase, actually you are creating a better, rougher surface for the pad to grip so stopping distances might decrease.

 

I know that. I'm trying to say slotted/drilled/etc rotors are not helpful to a huge percentage of their users compared to normal vented rotors. A fact unrelated to resurfacing said waste of money.

 

Slotted rotors serve a perpose for anybody. The slotts clean the pads keeping any hard glazed area's to a minimum. This helps keep the pads soft wich helps in braking and keeps noise to a minimum

 

I suspect you have read a lot of sales literature.

I respectfully disagree.

 

I don't really push or sale many slotted or crossdrilled rotors, and yes blanks are fine for most consumers but there is no downfall to upgrading, only gets better. Thanks for your opinion though.

 

I've had powerslot rotors cut 2x. After they were turned I cleaned out the slots (that were now not as deep) with a dremel. (these were on my last car not the max, but it doesn't make a difference)

 

I really dont think slotted rotors do much of anything for performance (I lean towards they hurt it). The only reason I got mine was because I liked the way they looked

I say they may hurt it because of the loss of braking surface, BlackbirdVQ was way happier with his brakes when he dumped the slotted rotors. I really dont push my brakes THAT hard so I think I can get away with the loss of performace for the looks. Either way, my brakes are better than most cars I have driven. The only car that really impressed me with its brakes was my old 9-3 Vector. That thing stops way to easy from 80mph to a dead stop at an unexpected Stop sign.

 

I've had ok luck cutting crossdrilled rotors, but poor luck cutting Saab 9-3 Viggin slotted rotors. Usually the slot causes a slight ridge in the finish on the other side. I was trying to take off .004" from each side. Maybe too much on a slotted rotor.

 

Should I trust a Straus or Pep Boy's to do it?
or find a local garage.

Thanks, Mike

 

I dont know what brand mine were (free), but i cut them with no problem.

Slotted rotor have a better heat dissipation and eliminate the gas that build up between the pad and the rotor.

 

no they don't. modern pads don't expel gasses under hard braking like they used to in the 70s, and the added surface area (i.e. heat dissipation) is a small fraction of 1%. for a street car, slotted rotors don't do anything but look different.

 

I understand what your saying about lots of shops being lazy, but drilling your own rotors? Don't they all have to be equally weighted? PM e with an answer please.

 

Its supposed to say, PM me with an answer.

 

correct!!!!!!slotted rotors are all about show on street cars......

 

Thanks for Hi-Jacking my thread with yet another nobody wins debate on slotted vs blanks rotors.
I already have my slotted rotors and couldn't be happier w/ them.
All I wanted to know was if anyone had success cutting them.

Thanks to all that actually helped. Mike

 

The other obvious choice is to leave them alone. 1 groove in your rotor will not hurt your performance and will eventually wear away. That way you don't have to worry about some goofball f*kin up your rotors.

 

By the way, the slots are supposed to heat the pad up for better bite on the rotor. That's what the guys on the Speed Channel say.

 

Trust me, it wasn't easy...It took a long time to come up with a design that was spaced perfectly even and be able to drill between the fins in the rotor. But ever since I've done this (about 9 months ago) I havn't had a problem with warped rotors. I use to warp my rotors about every 2 months or so. Don't try this at home

 

I had cut one set of slotted rotors, after a track event the rotors cracked on my way to work. There was a stress crack all the way from the outter edge of the rotor to the center of the hub. I am sure if I nailed the brakes harder they would have exploded on me.

I had IRotors 04 Maxima rotors coated in Zinc (still rusted out) and TTZ Calipers with Blehmco brackets along with Hawk HPS pads (my choice of pads on all my cars). Stopping power was worse than my cheap azz chinesse made 20 dollar a pop BLANKS. I hated my big brake kit, I decided to remove it and put back the stock stuff. My car stops better and accelerates better (less rotational mass vs big rotors) with my stock calipers and HPS pads. BTW my Irotors where slotted and drilled, I could have faded them without a problem.

I'm getitng some WedsSport wheels (light weight JDM wheels from TireRack) and possibly the Brembo GranTurismo brake package along with it.

 

Nice! You should love that brake kit, other than the price. I think Kevin (2kse?) is selling his for 1500 in the 5th gen classifieds. I've also been planning on getting the Wed sport wheels for the track, TC-005 16x8 I was thinking. Don't forget to make sure those wheels will fit over the brakes.

 

Blackbird.

Did you consider going for Matt's 2 piece 6th gen rotors? Good weight savings over the one piece OEM stuff. About 5lbs a piece I believe. And they weigh about .75lbs less each than the OEM 5th gen rotors (00/01).

 

In the end either have them cut which is a task or get new ones

i personally have slotted and I am going to replace with blanks cuz they were just for looks and didnt increase or decrease performance in any way
