what is the best make brake disc on the market to get without change the size?
I like to have dilled or groves.
I dont what to use the oem.
I going to still use the oem calipars, so it will have to be the same size disc

 

I got the same thought as well, a lighter disc ( 2 pcs) for performance improvement.
But there's only 365 mm 2 pcs drilled rotors on the market here.
They're perfectly fit 18" rims and slightly increase the brake torque by 4% though.


Sorry, not answer your question.

 

Only for aesthetics or do you need to improve your braking power ?

If aesthetics, ok, search for something non-OEM .
If you are searching for more power, you have to consider to change the caliper (then the whole brakes), because the problem is that part, not rotors!

 

Master Cylinder might need to be upgraded as well to have enough power to press those big pistons.

 

a quick way of having more stopping power is,

Get black diamond performance cross drilled and grooved brakes discs, they are the same size and improve braking, plus if you get better brake pads, that certainly helps as well,

if you calipers are colored then the discs will look sick trust me, i have them too

and they certainly slow you down especially when doing some high speeds on the highways.

Obviously bigger discs and bigger 4 pots will be better, but if you keep same size disc then its best to do what i done,

i recommend Black Diamond.

 

my rotors are getting low but not my pads so only change rotors for now and the steel pip lines too.
just what a little bit better than the stocks for stoping, not going on the track so no need for big braking power

 

For stopping power, absolutely don't forget metallic lines and new oil (to reduce fading) .

 

I going to get the lines this weekend in HK. but not going to change them until I get the rotor

 

Why not ?
Changing rotors doesn't need to replace oil ...

 

If you like the design, this is the best low cost OEM replacement rotors, ATE PowerDisc, an enhanced version of our stock ATE rotors.
