Slotted Rotors
Time to do the brakes and want to install slotted rotors. Who sells decent ones. I want to stay away from the "China" stuff!
|
Powerslots seem nice. I have a set but haven't run them yet.
|
Powerslots are nice so are Wilwood and Baer. I had powerslots and Wilwood on my mustang a couple years ago and both were great (wilwood was better but also more expensive). Right now on my ta i have the cheap ones from ws6store and they arent as good as the other ones but half the price and they are holding up well
|
keep in mind slots are just for looks. dont do anything to help you stop better.

yeah I thought drilled rotors were good. They kept cooler and are lighter than OE. Guess I was told wrong? lol

drilled and slotted are both useless for actual stopping. read up on the stickies on tech. years ago, 10 or more, pads were made differently, and produced gasses when under heave braking. the gas would actually build up between the pad and rotor like a cushion, called outgassing. thats when drilled/slotted rotors worked. now, pads, ALL pads (at least high performance ones) are made completely different. they dont make the same gasses which produce outgassing. now, all holes/slots do is take away from the surface area that you need for maximum braking.
the holes are prone to cracking, unless the holes are actually cast into the rotor, as apposed to just drilled through. the slots take away from surface area, hence reducing the effectiveness of the pads. the most youll see in actual race cars are some very slight, very shallow slots, or a wave pattern around the circumferance of the rotor. this is only to help clean the pad/rotor, or something to that effect. case in point: when i went to the IROC auction, they had rotors on shelves. the short track rotors, made for constant braking from 100mph down to 40, over and over again, were solid, blank rotors. carbon fiber, yeah, but solid blanks. |
so what kind of brakes would you recommend once I start my road racing project?
edit: sorry 426 Wedge I kinda took over without realizing. lol |
High quality solid blanks....Brembo makes 'em for a pretty good price.

you could get brembos, with ducts, and be done with it. or; you could get cheap rotors, with or without ducts. use them once or twice (per road course day) and toss them. you may end up with a warped rotor....never know. if you warp a brembo, youre out a decent amout of money. if you warp an autozone special, youre out alot less, and get brand new rotors with each swap. dont forget the pads also, theyre more important then the rotors. if you want one pad for driving/track, go with either hawk HPS or HPS+. if you dont mind swapping pads, bleeding brakes for every track day, then get a dedicated racing pad, like ferodos or the like. check out FRRAX and the roadrace section of ls1tech for more info. |
I ran powerslots for a few years and loved em. Never had a problem with them.
With the drilled rotors, the holes have a tendency to crack and brake over time. Good for a race car where you see limited use and you change them often. They keep the brakes cooler when racing, but no need on the street. |
If drilled is not good then how come I see a lot of Mercedes coming stock with them. How are they different?
I ran powerslots on my old truck they were good but dont have them resurfaced when its brake time. I resurfaced them when I worked at the dealer and only took off a minimal amount and after a little bit of driving they warped and I had to replace them with new ones. |

I have the TrackBrackets and its a very nice setup, there are 2 or 3 other suppliers that provide brackets for C5 conversion. Here's a link to get you started http://www.ls1tech.com/forums/showthread.php?t=353903 To give you an idea of the kind of temps you can see on a track day, the previous owner of my car 2MCHPWR (on this board, maybe he will chime in) melted the WS6 center caps out of the front wheels on my car at Pocono when he first started doing track days, that was prior to the C5 upgrade.....That's a lot of heat.

that is an excellent read. thanks 1qwikbird!

china rotors should only be used on cheap cars. I'm installing them on my sisters Chevy Malibu. You can't even get those rotors shaved off if they warp; they'll just crack.

I am told that some rotors have the holes cast and some are drilled, and that makes a difference, with drilled being prone to cracks. I cannot confirm that.

I heard that slotted rotors actually held brake dust and what not and cause the rotor to crack.
