At what point do you replace your rotors?

Dave:

I guess this will be elemental to folks here, but as I understood from a fabricator I talked to, the big expense was the custom hats. After that you were replacing only the floating rotors at about $120 each, which if they weren't drilled lasted a good bit longer. So maybe $600 (for the hats) going in isn't so bad.

Since your in Cumming, drop your rotors off at Cryo-Rem for the cryo treatment. Very reasonable and I've had good rotor wear with compared to stock 993TT rotors.

Steve can also get you the rotor hats to convert to slotted rotors. Just make sure the rotors they are machined for are reasonable and easy to get. That seems to be the big investment as mentioned.

For us stock class guys, will these rotors give us any problems with the scrutes? I hate these stock rotors but have not really found any other choice unlike my RSA brethren...

The AP & Alcon rotors are quite a bit more expensive than $120 ea.

Dave,

I'm late to this game... toss the rotors. Your thread brings back memories of why I got away from the OEM vented rotors.

Go slotted and eat the cost up front of a 2 piece design and never look back!

I am planning to go to slotted rotors after my current set. I have tried the cryo stuff, but they don't seem to last any longer than straight out of the box.

I used slotted on my previous car and they were great until the slots almost disappeared. They were readily available for an SC, as discussed not as easy to find for later models.

As far as the scruits, I have never heard of anyone called out for different rotors, as long as they work with the stock calipers.

Any other feed back on Cryo Treated?

Some like it, some hate it. I have never seen the benefit.

I've used FrozenRotors for years. I can't say how much longer they last other than yes they do last longer.

I have since switched to slotted rotors (still cryo) and have not replaced a set yet. I believe they are manufactured by Coleman. These last infinitely longer than Porsche.

The problem is the Porsche rotors are made out of some alloy of cheese. It takes nothing for them to crack. I was cracking them with hardly any wear. On the other hand they are cheap considering they are from Porsche. Switching to a better quality rotor makes all the difference.

I know these are available from frozentors.com and also from KVR Performance in Canada.

I've seen cars have notes in the log books for running aftermarket rotors in stock classes. They were all ones with aluminum hats though which are a weight advantage.

The problem for us heavy 993 pigs are no alternatives. The 964 guys have several solid disk options. I wish there was just a solid disk option.

There is for the 993 Turbo. The Brembo GTP brakes I run on my 930 use a standard 993TT rotor. You can get the slotted Coleman version from FrozenRotors. I'm sure Coleman must make them for the 993NA as well.
