i had just purchased slotted brake rotors from ebc. i heard they have had the need to be turned before installation because of runout. anyone in wisconsin know where i can get them turned? i have tried everywhere in green bay and cannot find anyone
 
where did you hear that?

if you have to correct them before mounting - I wouldn't buy them

I do not believe you can turn slotted rotors.

Whoever told you that does not know what they are talking about. EBC rotors come ready to be installed. I know this for a fact because we sell them.
 
it is placing the rotors on a brake lathe and 'grinding' them true. the older rotors (iron) would warp under the braking heat - so you would straighten them out by grinding them (while spinning) flat.
 
"Turning" a rotor is milling off the top few thousandths of an inch of the steel on both sides of the swept area of the rotor to make sure that the two faces are flat and parallel and that the rotor is a uniform thickness.

If the rotor is warped, you basically knock the high areas down to the level of the low areas; if you're turning new rotors, you're essentially removing any surface imperfections. I've never run into any new rotors that needed to be turned before installation; I'd agree with Quik--if you have to turn new rotors, you should just return them for a refund.
 
i'm not trying to jack the thread, but what are the best brand of rotors/ pads to get fir drilled and slotted? I was looking at the r1concepts pads and rotors and also the rotorpros.com rotors. Which are the better choice? or is there a better choice that i am missing? I'm looking to spend the least amount possible, hopefully between 2 and 300 for all 4 rotors and pads.
 
i had read it on the lincoln of distinction website. the person on there said that they caused the car to shake when he installed them, and after they were "turned" the problem went away

First, DO NOT get drilled rotors. Lets think about this; do you EVER see drilled rotors on REAL performance cars? NOPE Why? There are a lot of reasons... I'll just give you a couple. All of those holes drilled in that rotor decrease the surface area which does two things; makes for less friction (meaning stopping that isn't as good) and it allows for stress fissures (tiny hairline cracks) to find great places to start and terminate at (think Grenade without the boom) And of course, one of the final reasons; less surface area means less heat dissipation and a decrease in overall strength.

Go with standard or slotted rotors (very minimal material removal but still provides better cooling/cleaning of the pads as well as allows for gassing). Check out crygenicly treated (frozen) rotors; they've been proven to increase rotor life 100-300% over their untreated counterparts. They also provide better braking and cooling. Read up on it if you like... just google it. I know for a fact that www.frozenrotors.com carries PowerSlot rotors for our cars.

Pads... EBC ceramics, Axis and Hawk are all good names but remember that even the best semi-metalic will make SOME noise. I put Axis pads on my parent's volvo for them about a year ago and they work great; I run Hawk heavy duty pads on my truck (they make some noise though) and I've got EBC Red Ceramic for my LS.

This is all just my take on it... it's your car and your money
 
Well I Received The Ebc Rotors On Tuesday. I Finally Got The Chance To Install Them Tonight. I Took A Reading To See How Much Of A Runout There Was On The Rotors. On The Right Side, It Was .09. The Max Suggested Was .003. Then I Decided To Open The Other One And It Was Cracked Through. I Am Getting My Money Back After Complaining To The Person On The Phone And Computer. Car-stuff.com Does Not Have The Best Customer Service. Looks Like I Will Be Getting Something Else
 
Get solid rotors. They're stronger, dissipate heat BETTER, they DON'T eat the hell out of your pads and insure dirty wheels 100 percent of the time, and best of all, you stop alot better.

That cross drill slotted bs is exactly that. BS.

I had crossdrilled and slotted rotors (Baer) on my Mustang. I autocrossed them w/no problems whatsoever. They looked great and performed even
better. While it might be true it you raced SCCA events they might crack and not hold up. If you want them get them.
They look great and I got a lot of compliments at Car Shows as well as awards.

The Baer brakes performed so much better than stock.
Bottom line is get what you want. I wouldn't worry about the cracking, heat dissipation nonsense.

probably going to get the power slot cryo rotors. cheapest i found was 117.88 per side

Dont buy them from autopartswarehouse.com

I tried to purchase the regular powerslot rotors and received the wrong rotors (6 lug). I sent those back and ordered the powerslot cryo instead. Those were out of stock for 6 weeks... I called several times and was assured each time that they would be back in stock within 3-5 business days. Meanwhile I was having to wait on the refund from my first purchase. So all I got for my time (2 months in all) was 2 charges to my credit card and 2 refunds (6 and 8 weeks later). I will not be doing business with them again.

I'm still in the market for a set of front rotors, let me know what you find.

i found deals on these rotors for as low as 117.88. the only problem all of the websites seem to link back up to autopartswarehouse or car-stuff.com. guess ill have to pay a little more, but at least i know what i will be getting

Perhaps your right but my Slant Nose Widebody Porsche came with cross drilled rotors and the last few passes thru the pits at road races I saw NOTHING BUT CROSS DRILLED ROTORS, some are slotted too.

Do as you please but by stock rotors will be swapped out for slotted and cross drilled rotors.

BTW - Anyone want ot buy a front and rear set of rotors off my 2006 LS ? Less than 8,000 miles.
I'll let them go cheep.
 
Just to add to the mix....

I've had the same Brembo drilled/slotted rotors on my '03 LS and '06 LS for a total of 30,000 miles and have no problems with them what so ever. We drive hard and the rotors are still straight, true, crack and noise free. High quality rotors, properly machined are the key.

Those cheap rotors you see all over Ebay are stock units drilled on a CNC machine and mass produced with poor workmanship. That's why they are so inexpensive. So stay away from them because.....

You get what you pay for.
 
I need to see proof that a solid rotor dissapates heat better, since I don't believe it for a second. I do understand that a solid rotor "of the same size" will 'absorb' heat better due to the extra mass, however I find it impossible to conceive that all that extra surface of a cross drilled rotor won't cool more effectively.

Buying crossdrilled rotors in your stock size is risky when it comes to rotor life, due to this lower mass issue, however on a BBK (Big Brake kit) the mass issue is well, no longer an issue. If you like cross drilled rotors, get a BBK and lose the talk, the grief, the arguements and find yourself loving the cross drilled rotors.......I have them (BBK's) on two different cars and know the facts.....

Where did you get the Wilwoos set for your LS ? I don't see any Lincolns listed on there web site ? Cost ?
 
On that other thread you can contact the guy that did the conversion, he shouldn't have any issues doing others now......he can give you a quote.
