Where can I find slotted rotos?

[PeteBrown]

My near new front rotors are hot spotted and therefore I need new rotors. I'm thinking of slotted rotors because they offer the ability to let gas pass and many have said the cross drilled (even cast) are more prone to cracking.

However I have not been able to find slotted rotors for an '87 911. Does anyone have any suggestions where to find slotted rotors? Am I waisting my time with all this?

The car is a fair weather car driven on the street about 3,000 mi per year with about 5-6 DE days per year. Should I just stick with stock rotors or would cast crossed drilled rotors be better?

What are your thoughts on putting new pads in with new rotors? Should new parts be installed separately (e.g., new rotors/old pads or new pads/old rotors)?

Given my mix of street driving and 5-6 DEs I think Pagid blue pads would be a good selection. Any thoughts?

Hi

My usage is very similar to yours, biased a little more toward track use and less toward road use.
I switched from stock to Zimmerman cast cross drilled rotors, put on the AJ usa cooling kit, removed the rear dust shields, and used Hawk blue pads, all changes done last year.

As a result, I dropped my front rotor temps quite a bit, and never had soft pedal at the track.

Th hawk pads were tough on the rotors. this year, I am trying out Carbon - kevlar pads (KFP gold) to see if rotor life is better. The hawk are carbon metallic.

ATE makes slotted rotors, i think they call them powerlots or something, I know of one vendor that sells them, possibly pelican does as well, but I havent checked the catalog. There kinda cheap as well $120 for the front pair

Frozen Rotors

That's who I'd use...but that's just me.

I use plain jane Zimmermans on my 87 911. I do some number of DEs per year. I currently use PFC 90 pads for track and have also used Hawk Blues as well. I switch to Metal Masters for the street. The PFCs and Hawks don't work as well as the MM when cold plus the MMs are much cheaper. My 0.02.

'where can I find slotted rotors' ............try taking off the front wheel for starters!

To be quite honest, and I've been involved in motorsort for a while, I really don't think many drivers will feel a difference between slotted, drilled and std discs....but sorting out brakes and handling is the cheapest way of making a car lap faster.

Here's where I got mine.
