Looking for someone with information about slotted rotors. I am finally ready/ have time to machine up a set and have them installed, but I was wonder if someone with info could help me..........
1) the width of the slot
2) the depth of the slot
3) how many slots are in your rotor

Any answers would help me dearly, thanks again!

Scott,

I apologize about not getting back with you on that information. I'll try to get that information to you. However, if someone has it readily available then that's great too.

why not just buy them off ebay.. check they're feedback score.. and if good... buy them..

He's going to start machining these himself which would be a good thing. Probably get a better rotor and machine job with Scott.

Yes my plan is to run a set on my car and see about wear and what not. Once I have them on my own ride for awhile then I will probably be selling them(cheaper then powerslots and ebay).

Thanks Ken if you or anyone out there that has them could give me the info that would be awesome. I have one of my machinist ready to mill them in just need the specs.

-Scott-

awesome!

let me know ill buy some off ya

Cool!!! I've been meaning to PM you about where ya were with that project. :Beer

Yeah Slag its been too busy in my shop to work on "personal" stuff hopefully with this little down time and soon hopefully measurements from Ken I will be running them through. I'll keep everyone informed.

-Scott-

Ken,

where you able or can you get me those measurements sometime here soon? I want to get them machined up and installed within this week.

-Scott-

Scott,

I haven't forgot you. I've got a friend that has some LS slotted rotors brand new in the box. He's getting me the specs on it. Hopefully I'll have it to you this evening or tomorrow.

Well if i had some rotors here at work i probably could put them on the roamer and give you dimension accurate to .0001" for positional tolerances and hole diameters but needless to say i don't have any.. But i was going to ask you want kind of positional tolerance are on the whole locations on brake rotors, i'm guessing its not very tight tolerance is it?? Lets say someone measure the hole for a vented brake .25 but it was actually .2 or .19 or something, (just throwing out numbers).. will that reduce the strength of the brake.. Cause i read someone posted on here that those will sometimes crack after awhile..

I currently run the cross drilled/slotted rotors and my next set of rotors will NOT have the holes. I've seen and heard too many horror stories about cracks. The holes will definitely weaken the rotor making it susceptible to stress fractures and cracks.

The cross drilled rotors look good but I'm too old now to worry about what looks good on a rotor. I want stopping power!!

Thanks Ken!

I am only making slotted rotors, cross drilled rotors are not test proven enough for me. I have heard and read way too many stories about people having a paid $80k for a 911 and within a month they have it back at dealership with horible braking issues come to find out that the rotors themselves have cracked due to stress. Cross-drilled rotors are awesome for race cars and but not for everyday use especially in cold weather climates.

-Scott-

Scott,

I sent you PM with the slot information. Let me know if you have any other questions.

Ken

Thanks Ken,

I do have one other question and that is what type of brake pads do you use and are they dust-free as they call it? Also would it make sense to order Eibach Pro-fit springs and have them installed while I am having the brakes done?

-Scott-

Scott,

I use the Porterfield RS4 pads and they are virtually dustless. I've never had any problems with them and would replace them with the same thing. However, I'm in receipt of my StopTech Big Brake Kit so I won't be using the Porterfield pad on them. I'll be using their recommended brake pad.

As for the installation of the springs, I had my dealer install my Eibach's and rotors at the same time. They charged me like $250 to install those items with the alignment. You can do it yourself and save some cash but it was worth $250 of my time to have them do it.

Thanks Ken for all your info and help. I just called the Eibach dealer in Dayton and they want $389 for the ProKit, is that a good price? Then I guess I will have my dealership install them while doing the brakes. I am also having a local company powder coat my calipers during this time period.

-Scott-

That seems high. I paid around $270 for mine. There's a set on eBay going for $233 plus shipping.

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7965286402&category=33582&sspagename=WDVW

They show up there from time to time at a good deal. I contacted them quite sometime ago to be a dealer but haven't got set up with them yet.

Well hello to all, the mission is complete I just put the finishing touches on my first set of slotted rotors. Install should be next week when I get my Portfield pads in. Here are a few pics of the final product.

I am very interested in a set of these...

Dealer states I am in need of brakes in roughly 5000 miles. They also want $326 to do the front brakes alone. $100 for parts (pads). Since I can readily get performance rotors and pads for all four corners for $350, I will be going that route. The problem is not being able to find rotors that are not drilled. I drive 80 miles a day in traffic and DO NOT want drilled rotors.

Send em an email and I will gladly buy a set from you if they are working out for you alright.

Thanks!!!

Powerslot makes great cadmium coated slotted rotors for everyday use and without structural integrity problems associated with cross drilled rotors. Even big names like BREMBO had issues to their ls lineup.pn#s as follows :8160psl and r for right,these are fronts.8161psl and psr are rears and retail for $115.99 each.

Tyler,

Actually tomorrow my LS will have the brakes installed and the Eibach Spring Kit also installed. I will let everyone now how they perform as of wednesday afternoon. I am quite excited to see how well she respondes. I will also post pics of the brakes actually on the car too. Until then thanks!

Well boys and girls,
The slotted brake rotors, portfield pads and the Eibach springs are installed. I love it, looks good brakes feel like they are stopping compared to my old set. I am waiting to put it thru its paces once I get the recomened 100 miles on them. Here are some pics of the finished product.

Looks great! Now you just need to put in some braided stainless steel brake lines and you'll definitely feel a harder brake pedal. I put the Stoptech lines in mine and it made a tremendous amount of difference.

that makes me want to lower mine. That looks awsome and once you decide to start selling these please post.

- is it me - or do they look like the rotors are on backwards...?

- is it me - or do they look like the rotors are on backwards...?
No, that picture is of the right rear wheel. The slots are going in the right direction.

my rear calipers are straight up and down - that looks like a front wheel.

That's the left front wheel. The caliper is on the "rear" of the rotor.

so that means it would be on backwards (on the wrong side).

Mike, are you sure?

Ken - here's a pic of your front wheel

I guess you're right. The rotor is on backwards then.

THAT ROTOR IS BACKWARDS. WILL IT AFFECT? MAYBE :monkey:

common problem - it tends to wipe the brake dust down into the hub. Not a disaster but should swap them.

sorry dude - didn't mean to pick out an issue on this thread.

I bought mine well over a year ago off of eBay from CC Rotorworks. Paid like $270 or so plus shipping. They've been great. I'm getting ready to take the complete brake system off and put my new StopTech Big Brake system on. I'm just waiting to get shocks so I can do the whole job at once.

Great Scott they are on backwards I either labeled them wrong or the techs installed them wrong. SH*T no big deal have them swapped out to right side in no time thanks for the pick up QuikLS. But all in all the effect is the same, I dont see it causing a major problem. Will change soon, have Jaguar issues now to deal with, so soon they will get flipped around.

same setup I am running.

I was always shown and told how he had them on was proper if they were also cross drilled... it helped for better cooling of the rotor itself.

Check this link out

http://www.baer.com/support/TechTips.aspx?TechTipID=2

I've seen a lot of cars with this rotation (including mine now).

As far as i remember unless you have a curved vane (slot) is when it only matters what direction they're in... straight or plane vanes are non-directional. But as far as the rotor cooling itself internally as it moves I was always shown and told the above link is how you want to do it. Brake dust isn't likely to be a problem either way based on the rotation (nothing incredibly noticable) but the point of the drills and slots are for cooling and less brake fade.


Any opinions?

Forgot to add to the post above -^

http://www.stoptech.com/tech_info/faqs.shtml#16


The reason i hear most people saying they cracked or warped on them using cross drilled / slotted is likely due to the incorrect installation of the rotational direction needed... the rotation allows air to pull in better and reduce smear...

Refer to the StopTech link above for further information.

You are right! I have seen tech articles that advocate both directions. I think if it were me, I would go with what ever the rotor Mfg. suggested. Quik's way is how I always thought that slots were supposed to go, but now I would go with the Mfg.

Speaking of brakes, has anyone weighed the stock brake/caliper setup and compared them with a quality big brake/caliper setup? Are the big brake and custom calipers significantly heavier or are the custom setups actually lighter?

Looks good have u ever thought about making dimpled/slotted they are not drilled they work pretty good had some on my 99 camaro they were great.
got them from http://rotorpros.com/index.htm. thinking about buying some next week will post pics when i get them.

Ken, would you weigh your new big brake kit and compare it to a stock setup when you install the Stop Tech kit?

Ken, would you weigh your new big brake kit and compare it to a stock setup when you install the Stop Tech kit?
I didn't do a weight comparison when I installed the StopTech system. Considering the size of the calipers and rotors I'd have to say the StopTech system weighs more but in the big scheme of things the weight difference would be unnoticed.
