2-piece stock size rotors?

[jm1681]

As the title says, I'm just wondering if anyone has seen or knows of any stock size 2-piece rotors available for these cars.

DBA 5000 series rotors

Kind of digging this up. Is there no other choice ?
Racing Brake has a reference but I read less than stellar reviews on their rotors' durability on Nasioc.

You will gain more performance by just getting the right brake pad setup for your application. There are a few reasons why 2-piece rotors aren't exactly the best way to go in stock sized applications.

Well I already run Carbotech XP10s (even with the Porsche brake spoilers http://www.ft86club.com/forums/showp...2&postcount=31 ) and I still have nasty vibrations after trackdays. My understanding is that I overheat them and thus a 2-piece rotor would help dissipate heat thanks to its aluminium hat.

You might want to give this a read.

Thanks. So ...

The contribution of the conductive mechanism is also dependent on the mass of the disc and the attachment designs, with disc used for racecars being typically lower in mass and fixed by mechanism that are restrictive to conduction.

This means an aluminium hat reduces heat transfers? Good to know!

I would pick CSG Dave or Mike's brain about why they feels 2 piece rotors aren't good on stock and additionally would also stop being a **** on the internet

Huh?

Calum is trying to help you. You indeed don't understand what's happening to your rotors and he's trying to point you in the right direction.

Refer to this about your warped disk from heat

The pulsation may also be pad deposits, not the rotors "warping".

[Tenament05]

^^ again, refer to http://www.stoptech.com/technical-su...nd-other-myths

"
Depending upon the friction compound, easy use of the brakes for an extended period may lead to the removal of the transfer layer on the discs by the abrasive action of the pads. When we are going to exercise a car that has seen easy brake use for a while, a partial re-bedding process will prevent uneven pick up.

The driver can feel a 0.0004" deposit or TV on the disc. 0.001" is annoying. More than that becomes a real pain. When deposit are present, by having isolated regions that are proud of the surface and running much hotter than their neighbors, cementite inevitably forms and the local wear characteristics change which results in ever increasing TV and roughness."

Yeah I got the d*ck (so to speak), thanks.

I do know discs don't wrap, I did read Carroll Smith back in the day too. My point is exactly to increase heat transfer to keep the rotors as cool as possible. As a matter of fact, aluminium is indeed more conductive than any steel alloy; which led me to believe an Al hat would help.

Turns out it doesn't according to StopTech, I was wrong and I thanked Calum. I don't see how I am being a d*ck here. There was no sarcasm in my post.

Sorry, sarcasm (or non sarcasm, in this case) doesn't travel well over text.

But definitely give Stoptech's white papers a thorough read though. I saved those long ago and they've saved my bacon more than once. Especially the myths one to ease my mind/set me in the right direction.
