Need new rotors [Archive]

I've done some research on s2ki on new rotors as I blew mine out at LT. There's only about $100 difference between all the options for a set of rotors, so that's not a major factor.

I was pretty sure I wanted drilled and slotted to keep the rotor temp down when I do track/xcross, but that weakens the rotor. I hit the brakes hard at the track, ask Joe. Plus you lose braking surface area with drilled/slotted, something that doesn't make sense to me.

Drilled/slotted is supposed to allow brake pad gases to escape, but how important is that? I bought ceramic pads that we put in so I could get home. I read some posts that say the newer pads don't put off these gases anymore. Is that true? I'm of the opinion that drilled/slotted is just for the bling-bling of it all.

Starts to make more sense to do what Modifry did, put in cooling ducts and run stock rotors.

And then what's this stuff on cryo treated rotors? I like the idea and will probably do that.

So right now I'm leaning towards cryo treated OEM or OE equivalents (G3000s from Cobalt) and put in cooling ducts if and when I decide to do that. What do you guys think?

i think slotted would be good. there are also dimplied, they look like drilled but no weaking effect. check out www.tirerack.com for some ideas

IMO the stock rotors are good enough for anything you can dish out & while you're at it upgrade to a higher spec pad. I wouldn't even bother with cryo treating.

www.stoptech.com has some good tech articles & FAQ's.

Cryo treating has been proven time after time to reduce or eliminate warping and extend the life of the rotor. That's why I purchased a set that was cryo treated.

Agreed that having them drilled and/or slotted isn't needed but they look great. I still believe that the holes/slots decrease rotor temperature by adding a cooling effect but every driver is different so it's difficult to measure w/o doing your own experiments. I believe that the cooling effect of the holes/slots at least offsets the loss of material in the rotor.

If you want cooler brakes then adding ducts will help without a doubt. Stock rotors are good, if you get a set that are cryo treated they will also last longer. I got mine from Jcarlton on S2ki, call and talk to him, they know an awful lot about brake rotors.

Just don't pay any more for a stock rotor than you have to, I belive H&A Accessories had good prices. Also, if you want my old set your welcome to them. They've been turned once and probably are good for at least another couple track days.

I love my Willwood setup. No fade at all during the track day Friday. Still had plenty of pad left after both Jeremy and I were finished. No gas left, but plenty of brake pad.

jcarlton's profile doesn't show a number. I'll try a pm. Appreciate the offer on your rotors, but I want newbies. Thanks anyway!

Ask for Sherwin. He is on S2ki from time to time.

Tom, I think with the braking style you have, you would be happy with a nice set of Brembos from Comptech:D

Why, they're only $3999 and the look nice to boot!

Careful with Brembo's (or any drilled and slotted rotor) using ceramic pads. I had a set and warped them the first time I hit the brakes hard. I called Brembo and asked why a set of $350 rotors would warp so quickly. They told me the drilled and or slotted rotors could not handle the high heat the ceramic pads generated. 3 different brake places would not turn drilled or slotted rotors. They went into the garbage. I put on the cheapest OEM rotor I could find at Advanced Auto Parts. They were still on the car 50k miles later when I sold it. I found the cheapest way sometimes is the best way. Use them and abuse them, then replace. If you can get stock rotors/pads and that stops you ok then go the cheapest route. I consider brakes a wearable item and abuse them. I would rather use my brakes then down shift. Its much cheaper and easier to change a set of brakes then a clutch.

Hey Tom, you might want to check out the new site I posted under the for sale forum:

They have a good selection of brake kits and stuff for the S.

Tom, you don't need flashy brakes for any thing that you do. If you had a race car then maybe things would be different. All you need, even for track days, are some aggressive pads. Get OE rotors and forget about all the holes and slots. That's just for show anyway... at least on OE sized rotors with OE calipers.

I had some Hawk HP+ that worked pretty well. I would also just look around in the S2ki racing forum. I think alot of people are happy with carbotech pads. I think for the next auto-x season I'm going to run some mean pads.

... unless you want bling.

Lee,

Do you use Axxis pads? Which one do you recommend?

At little Talladega I used the Cobalt GTS pads from the Go Fast Lab. I like them but they can be a little noisy on the street.

We put on those Morse ceramic pads at LT. Here's what Tire Rack says: According to durability tests, ceramic compounds extend brake life compared to most other semi-metallic and organic materials and outlast other premium pad materials by a significant margin – with no sacrifice in noise control, pad life or braking performance.

Will see how they do at Xcross Sunday. So far they seem fine but have less bite than my OEMs, but I think that's because of the new circular slotting on my rotors.http://www.s2katlanta.com/%7Es2katl/forum/images/smilies/laughing-smiley-007.gif Thinking of getting them turned after Xcross.
