I bought a car with many many aftermarket parts and one of the upgrades are upgraded brembo cross drilled and slotted brakes rotors with T2 calipers...Does anyone know what size the rotors are? Also would anyone know if I can buy 1 stainless steel line from for the drivers side rear?

 

the brembo rotors shoud be the same size as the oem rotors, thus allowing you to use the factory calipers.

the shop manual lists them at 276mm x 22mm or 10.87in x 0.87in

as for the brake line, i haven't seen any where selling them individually. why do you need just one? if you change just one brake line to an ss line i fear you may imbalance your braking (ie make one side stop harder than the other) and your car will pull to a side when slowing.

 

yeah they are I just bought some and they where the same exact size.

 

Cross-drilled is not an upgrade.

Ted elaborate please

I am glad my brembo's are OE style

 

Thanks Ted but i didn't need a science lesson on brake rotors...I merely asked how big the rotors were compared to the stock size.

 

I don't understand your logic. You can't just bolt larger (or smaller) diameter rotors onto the stock set-up without running into fitment problems. Are you smoking crack or something?

Stock replacement has to fit stock specifications.

you beat me to it Ted. I was going to explain a little about the cross-drilling.

 

Not that i know anything, but how come the new Porsche CarreaS4 has xdrilled-slotted rotors?

Im glad i found this thread so i dont waste money on them.

 

so x-drilled = bad, but slotted = ok?

 

Porsche rotors are not cross-drilled but rather cast with the holes in the mold. I think this significantly reduces the potential of the holes being a stress riser. In addition, Porsche uses a very large rotor. I suspect that the large rotor is used for increased leverage, not necessarily heat soaking mass. The rotor is then large enough and "mass"ive enough that there is plenty of heat absorbing ability despite the holes. Without the holes, they would likely be prohibitively heavy.

 

The only rotors brembo sells for the FC are OE style.. other companies do the cross drilling/slotting afterwards...

At least that's what Brembo told me...

 

Everyone seems to want cross drilled or slotted rotors, but they don't seem to realize they don't have any real use for them. There are about two people on this forum who are actually fading out their brakes.

Note bikes and high-end race cars have drilled rotors so there are obviously applications where they work.

 

Ya it does, because then the grains in the metal form around the holes. In a regular rotor where they "drill" the holes, the grains are broken up and theres a loss of continuity within the cellular structure of the metal.
Its the same reason forged anything is better than the oem stuff.

 

hey gtudrifter you send my freaking pipe yet?
